Network Software

Network software consists of programs that manage the network, provide srevices and allow computers to communicate and share information on the network.
Network Operating System

The Network Operating System (NOS) is the most important software on a network. The network operating system organizes and manages alla the activities on a network. On some networks, one central computer, called a server, is responsible for running the network operating system. Netware, Windows 2000 Server, Linux and LANtastic are examples of popular network operating systems.

Network Driver

A network driver is the software that allows the network inteface card in a computer to communicate with the network. The network driver must be compitable with the network interface card and the operating system on a computer.

Server Software

A server is a computer that makes information and resources available to other computers on a network. Server software enables a server to perform a specific task. For example, e-mail srver software allows a server to process and manage e-mail messages. the server software must be compatible with the network operating system.

Application Software

Application software consists of the programs that run on computers connected to a network. Application software includes productivity programs, such as word processors, spreadsheet and database programs, and customized software, such as programs used for inventory and accounting purposes. Application software can be stored on each computer connected to the network or on a server used only for storing application software.

Management Software

Networks that connect several computers often use management software, which allows network administrators to organize and manage a network more efficiently. Management software can help maintain network performance and alert the network administrator in case problems or errors occur on a network.

Network Hardware

Network hardware includes the physical devices used on a network. All networks require network hardware to function.

Computers

The most important job of a network is to link computers together. When computers are linked, the people using the computers can be work more efficiently. Computers connected to a anetwrok do not have to be the same type. For Example, a network could conatain desktop computers, such as IBM-compatible & Macintosh computers, or portable computers, such as notebooks and Personal Digital Assistants(PDAs).

Resources

Anetwork resource is a device that computers on a network can use. The most common type of network resource is a printer. All of the users on a network can send documents to a printer that is connected to the network. Other examples of netwrok resources include fax machines, tape backup units and file storage devices, such as hard drives.

Cables

Cables are the wire that connect computers and resources on a network. Many different kinds of cables can be used, depending on the type and size of a network. The type of cable used often determines how quickly information will tarnsfer through a network. For some large networks, many miles of cable may be required.

Connectors

A connector is a device that joins network together. When two networks are connected, all of the computers on both networks are can exchange information. The most common types of connectors are bridges and routers.

Network Interface Cards

A Network Interface Card(NIC) is a device that physically connects to a network and controls the flow of information between the network and the computer. NICs are installed inside a computer. The edge of the network inteface card can be seen at the back of the computer. ANIC has a port where the network cable plugs in.

Memory Upgrades for Vista Operating Systems

Now that Vista is officially out, many of you are dying to run out and buy it. I know that many will upgrade without first checking system requirements or system compatibility. This article is for you. When you try to install Vista, you may quickly find out that something will need to be upgraded. Most likely it will be RAM, video or both.

First we will look at memory. I am talking about system memory or RAM. Before we go further, my associate says I need to write about something more important. That is the peripherals, things like mice, cameras, scanners, printers. For most of these, you will find that there are no Vista compatible drivers available. The chain stores are going to be pushing Vista systems, but be patient and wait for the hardware to catch up. Here is where you will do better talking with your small neighborhood tech shops to find out if your computer will work with Vista.

For those who want to upgrade for Vista, additional memory may have to be installed. RAM (Random Access Memory) is used by the system to run applications. You can never have enough RAM. The current standard has been 512megs. But as the software becomes larger, system resources really become an issue. This is true with the new security suites like Norton or McAfee. Today, I would not consider a system with less then 1gig of RAM. You can run Vista on 512megs, but you would not be able to enjoy all the features and your system may perform very poorly.

To speed up your system and upgrade your RAM, you need to know a few details. You need to find out how much RAM you have, what type/speed, and how much your system will support. To find out how much, go to your START button, right click on My Computer, then select Properties. After the dialog box opens, look down to the bottom right. You will see information for the type and speed of the processor. There will also be a number indicating the amount of RAM installed. It will read 265, 512 or 1024 gigs.

On many of the mass produced machines, there may be an odd number like 448. That is because system memory is shared with the video. To find out the type and how much the system will support, check the system documentation. Check the specs in either the printed materials or check online. Sometimes there are stickers on the front. Look for something that reads like DDR XXX, (DDR400 for example), or PCXXX (PC3200 as another example).

If you have never done this, or are not comfortable opening your computer, you may want to get a service technician to install the RAM. They will still need all the above information. Now we can open the computer and install the memory.

1) Unplug the power on the computer. Most motherboards still are powered, even with the power switch off. So remove the plug completely. Ok, pull the power and unplug everything that is attached to the tower. Mark them if you need to, so you can put them back.

2) Lay the tower on the right side and remove the left side cover. Inside you will see many colored wires and cables. Carefully part these until you can get to the memory slots. They are called DIMM slots. There can be two or more depending on the motherboard. They will be located close to the processor (big metal fins with the fan motor). You will also see the existing memory stick.

3) On each end of the DIMM slots there is a white clip. Make sure they are pushed back to the opened position. Look at your new stick of RAM. You will see 1 or 2 notches. These will match up with dimples in the memory slot. Carefully line up the stick and firmly press it into the slot until you hear it snap into place. Now, secure the two locking clips and you are done.

4) Stand the system back up (leaving the cover off at this point). Plug in the mouse, keyboard and monitor. Plug in the power and fire the system up. One of 2 things will happen. If everything is alright, the system will boot like normal and you can watch the new amount of RAM count up on the screen. If this happens, then you are finished installing the RAM.

The second thing that could happen is the machine starts beeping and will not boot. Do not panic, all this means is that the RAM is not seated correctly. Simply shut it down and unplug the power. Remove the new stick of RAM and reseat it again making sure it snaps firmly into place. You may need to press a little harder than you think. Test the system again by rebooting. Once you are done, replace the cover, put the tower back, and attach all the accessories.

Let me just say again, if you are not comfortable opening and working on your computer then you will be better off letting a technician help you.

Types of Networks

There are many types of networks used by businesses and organizations. Since each business and organization has its own needs, each network is unique.

Network Size

The size of a network can often determine which type of network a business or organization should use. Different ways. For example, a network with over 1,000 users is organized differently and requires a variety of components not found on a network with only five users.

Network Cost

The Size and type of a network determine its cost. The larger the network, the more costly the network is to build, set up and maintain. In addition to needing extra hardware and cables, a larger network also requires specialized cabling and computers to link users and devices that are far apart.

Local Area Networks (LAN)

A Local Area Network (LAN) is the most common type of network found in businesses. Local Area Networks connect computers and devices located close to each other, such as in one building. Local Area Networks connect from as few as two computers to usually no more than 100 computers.

Metropolitan Area Networks (MAN)

A Metropolitan Area Network (MAN) is collection of LANs. Metropolitan Area Networks connect computers located in the same geographic area, such as a city or town. For example, a college may use a Metropolitan Area Network that connects the LAN on each campus throughout a city.

Wide Area Networks (WAN)

A Wide Area Network (WAN) connects Area Networks and Metropolitan Area Networks together. The networks that make up a Wide Area Network may be located throughout a country or even around the world. When a single company owns and controls a Wide Area Network, the Wide Area Network is often referred to as an enterprise network. The Internet is the largest Wide Area Network.

What is a Network?

A network is a group of connected computers that allow users to share information and equipment.

Network Size
A network can be any size. For Example, connecting two home computers so they can share data creates a simple network. Companies can have networks consisting of a few dozen computers or hundreds of computers. The Internet is the world,s largest network and connects millions of computers all over the world.

Logging On

Network users are usually required to identify themselves before they can gain access to the information on a network. This is known as logging on. Each user must enter a personalized user name and password to access a network. By keeping this information secret, users can prevent unauthorized people from accessing the network.

Sharing Information
You can use a network to share information with other people. Information can be ant form of data, such as a document created in a word processing program, a picture drawn in an imaging application or information from a database. Before networks, people often used floppy disks or any other storage device to exchange information between computers, which was a slow and unreliable process. With networks, exchanging information between computers is quick and easy.

Sharing Resources

Computers connected to a network can share equipment and devices, called resources. The ability to share resources the cost of buying computer hardware. For example, instead of having to buy a printer for each person on a network, everyone can share one central printer.

Sharing Programs

Networks allow people to access programs stored on a central computer, such a s a spreadsheet or word processing program. Individuals can use their own computers to access and work with the programs. By sharing a program, a company can avoid having to install a copy of the program on each person's computer.

Searching For The Free Software Directory

If you are constantly browsing the internet in order to find Download free software, you will have to take your time because its finding is not likely to be an easy task. Most business companies are likely to consider thus type of free payroll software as the perfect tool in order to increase their selling opportunities. This software should be regarded in a whole new light because it is not the perfect solution when there are some businesses involved along the process. The payroll software is used in order to process all the employee payrolls in an e3asier manner without having to worry about too many details. The software will also help the company in order to track the vacation time and tax withholding; there are plenty of benefits when it comes to using the Free software directory on a regular basis.

But if you are interested in finding a Download free software just for your personal use, you should be aware that this finding can be transformed into a daunting task in case that you do not provide yourself with all the available resource that are to be found on the internet. You will also have to make sure that you can rely on a particular program without being scared by the potential viruses that can be brought along when downloading a particular program.

For instance, you may search for the so called open source software that can provide you with all the programs you need for your personal computer; this software is normally free when it comes to its usage and all the source codes will also be available for you. These codes are available for every user who is interested in redistributing, modifying or using them for his personal needs. The user can also take advantage of the unlimited freedom when it comes to using these open sources; but they are plenty of people who remain quite reluctant to using the online open sources on a regular basis. The Free software directory is not to be regarded as a menace anymore; on the contrary, you should become fully aware of all its opportunities.

The traditional idea that states that a value of every piece of software is likely to depend on the price you pay in order to get it is totally wrong; this is simply not the case when it comes to the modern techniques that can be provided by the internet. The Download free software is to be use without having to worry about its value; it is going to work for sure because it is especially designed in order to provide quality services for every user who is confident enough in order to use it. The Free software directory is not likely to come along with inferior quality; on the contrary, the open source is to be trusted for its quality services because they can be even better than the ones being provided by the paid sources.

The open sources will allow the constant sharing of information as well; the computing community will be able to stay in close contact to everything that is likely to happen in the virtual world because it will take advantage of real freedom when it comes to customizing the already existing source codes. These changes will be performed according to the user’s preferences and every user should be aware that free does not stand for inferior. The Free software directory is to be used relied on because it can provide you with all the information you need.

The open source is also blamed for the opportunities that can be provided thanks to its services; people are not familiar with the concept of free usage. On the contrary, they are used to pay for all the intellectual rights n order to use a particular program. They are not likely to rely on an open source that is free because they do not trust this type of service that can actually spare their time and money if properly used. But sometimes the open source is not as free as you might think in the beginning; there are some cases when this source will have to advertise a certain company in order for the users to be able to take advantage of all its programs and source codes. The open source can also advertise a particular product in order to sell it to the visitors who are accessing the Free software directory on a regular basis.

Actually, nothing is likely to come completely free of any charge; even the simplest articles that are used in order to create the web content are not totally free because a company is likely to use them in order to advertise its services or products. However, you will have to learn to appreciate the quality things and you will not have to stay away from a particular directory that can be very helpful for you just because it is free of charge. You will have to learn how to trust the free directories that are offering downloads in order to enjoy things that are not likely to be available forever.

An Introduction To Storage Software

All businesses face the challenge of storing their data easily, inexpensively and in a timely fashion. Initially, companies used tape-based systems to store data. There is now a rapid change to disk-based systems. At the same time, there has been a change in the software that supports this function and manages the stored data.

With rising numbers of branch offices, servers and amounts of data, storage needs are continually increasing. Organisations need to invest in systems that will save and back up data. This is where storage software comes in. It performs a threefold task:

• It simplifies control and management of hardware resources (devices and networks).

• It assures backup, archival and recovery of data.

• It takes care of replication and copying of data as it is created or downloaded.

While older systems of storage were more time intensive, the newer ones are more investment intensive. Many new storage software tools aim to reduce the cost of disk-based storage to encourage adoption of the newer technology by all sizes of organisation. Some providers also offer hosted services that are more scalable and affordable for small and medium-sized businesses.

Most storage software solutions rely heavily on hardware options. The ideal combination is a system where the software and hardware work together for an optimal performance and high level of flexibility. Many software storage providers partner with hardware manufacturers such as Dell, IBM, Fujitsu and HP to offer solutions like this. Larger players have acquired storage specialists such as Veritas and StorageTek so that they can offer these services.

This consolidation is not necessarily a bad thing. It means that more established players will offer bundled products that include additional features such as content management systems within the storage software to allow integrated retrieval and archival processes.

Wireless Networking: Do You Need It?

There has been so much hype about wireless networking that it is sometimes hard to get to the important question: do you need it? To determine whether your notebook computer needs to have wireless networking capabilities, you need to understand what it is first.

WLAN

WLAN stands for Wireless Local Area Network or Wireless LAN. Wireless network cards use the IEEE 802.11 standard of wireless transmission. There are other wireless networking standards, such as Bluetooth, but the 802.11 standard is the preferred networking solution. The Wireless Network interface was developed originally for interfacing among computers connected through a local area network, but it is now also being used for Voice over Internet Protocol (VoIP) and internet access, just like the standard Local Area Network interface.

A Wireless Networking environment has no need for complicated wiring to accommodate data sharing and internet access. The wireless network uses one or more Wireless Access Points or Wireless Routers to transmit the signal. An Access Point has an antenna and an Ethernet port, which must be connected to a broadband modem for internet connectivity. A Wireless Router adds several more Ethernet ports to allow a combination of wired and wireless connections. The Access Point or Router acts as the radio frequency transmitter and receiver (radio frequency electromagnetic waves are the medium through which data packets are sent and received). This Access Point interfaces with devices (computers, PDAs, IP Phones, and other Access Points) which use 802.11 wireless adapters.

Wherever there is an 802.11 wireless access point, a wireless networking-capable device can access that network and, generally, the internet.

Do You Need Wireless Networking in Your Notebook Computer?

Whether you need wireless networking depends entirely on you. Wireless networking capability is always a wonderful feature to have in a notebook computer, but there are scenarios where wireless networking is definitely necessary.

If you want to have a tidy office or home network, wireless networking is for you. Moreover, if there are many users in your local network or if the number of users is expected to increase, a wireless router is not limited by the number of Ethernet ports on the router. Please note, however, that a wireless network connection is not as reliable as traditional Ethernet connections, and wireless connections are susceptible to radio wave and electromagnetic interference.

If you are a freelancer, a reporter, or in another position where you frequently travel, Wireless Networking is invaluable. Wireless Networking is the most widely used form of public internet access all over the world. With a wireless networking card, you are guaranteed an internet connection, as long as you can find a wireless hotspot.

For interfacing with personal devices like PDAs and cellular phones, Bluetooth is a more common option, but Wireless Networking is absolutely necessary for wireless internet connections.

Wise Steps To Buy Laptops And Other Electronic Products

In 2008, it will be very normal if you buy electronic products in the internet world. I think it’s not modern anymore if you go to a mall and review each product there. If you want to buy a new PC or notebook, try to find the review in the internet. There are plenty of full reviews there so I think you will learn much more than if you go to a mall or electronic dealers in real world. What more interesting is, you don’t need to go out from your home. You can read about different products, different brands in front of your computer.

I always went to electronic malls when I had time to check new products. I checked their prices and performances but I realized I was just wasting my precious time. Start from early 2007, I always buy everything online, start from games to new notebooks. Even if you do not want to buy electronic products online, you could at least try to find out what you want with your internet browser.

If five years ago new PCs or other electronic products are designed for children and nerds, these days it is easy to find new computers for your need. Many companies like HP or Dell produced their own business laptops. With cheap prices, you could get the best performance from new notebooks. It is the same with PCs. You do not need to search for old PCs if you have a tight budget, you can expect PCs which specially designed for people like you.

Computer companies know people have different objectives. There are people who buy new computers for games but there are also people who buy new computers for their jobs. However, there are too many products released every day so I think the best option for you is to search in the internet what suits you most. It will be pretty hard and very time consuming for you if you try “traditional way” (i.e.: go to mall and search for new computer, etc.). Buying new electronic products online is the most effective way at the moment.

The Features And Benefits Of Pc Cables

For all those individuals who have a personal computer, or what is called a PC, you know that you have to have cables for your computer to work. It seems like everything in this world is run off cables right? A PC is no different. When it comes to PC cables, is can get pretty complicated because technology is constantly changing and new cables are always popping up out of nowhere. Even though PC cables are changing at a rapid pace, there are still those cables that every PC needs.
Every personal computer is different. Some are newer than others and some are just simply better than others as well. Whatever personal computer you have, one thing that they all share in common is that they all use coaxial cables, twisted cables, and the optic fiber cables. Coaxial cables come in two forms. Regular coaxial cables and thick coaxial cables. The twisted cables usually connect your PC to a phone line. They come in different forms as well. Twisted cables come either in an unshielded or shielded form. The shielded cable protects the cable better than the unshielded. The optic fiber cable is probably the most important cable out of these three and it is the most expensive as well. This cable has the ability to send information at a 100 Mbps or 1 Gbps speed. This cable is vital to your computer working well and properly.
There are several cables that make your PC function at full capacity. The three explained above are just to name a few of the number of cables that connect your PC and make it work great.

How Important Is A Cpu Fan

The computer may look like a very powerful and intelligent device but without the help of the various parts, the computer is absolutely nothing. We all know about the hardware and software parts of a computer but among them also there are such minute things which do not comes in our notice easily but are something very indispensable. These are very small and useful objects which sometimes prove to be very important for even performing the major tasks. In this context, variety of things being used in the PC can be uttered like the RAM, hard disk, CD ROM, motherboard, CPU fan etc. Let us pick up one object from among these and discuss widely how important even the minute parts of the computer are.
The use of the CPU fan perhaps could have been denied but that is not possible. CPU is the most important organ of the computer without which the operating system can not be run. It is the CPU that makes the computer operator to write, store, send, download and make project etc. very easy. What does it take to make your tasks happen? Stating them is the first step towards its realisation, the realisation of the importance of the CPU. For the CPU to run what is vital is the CPU fan.The CPU fan is the most simple and ultimate thing that keeps the CPU cool and workable. Due to the excessive pressures and heat, the CPU becomes very hot and under such circumstances it is the CPU fan that makes the CPU capable of working properly. This small part is fixed in the inner part of the CPU and starts working as soon as the CPU is started.The CPU is a combination of a number of parts namely the motherboard, memory, the arithmetic and logical components etc. the task that is performed by these components of the CPU are no doubt the very important ones. Therefore when all these will work continuously and together, it is very natural that these will get a high temperature. Probability is also there of these components being burned due to extreme heat and work load. In order to keep them cool and to give them sufficient air to cope up with the situation, the CPU fan is a must. The price of the CPU fan, if bought alone and not altogether as a CPU, will be less. Based on the function and size though it is very important, but still there are facilities of availing these in reasonable prices. The used CPU fan is also another thing that can be had in very low prices and that too in workable conditions.For a computer user the importance of the CPU fan is not at all a new thing to describe and he also is well aware of the utilities of this hardware part. Therefore from now onwards you too can lower the price of your computer parts to make your computer purchase in a reasonable rate.

What Is Ethical Hacking?

An Ethical Hacker is an expert hired by a company to attempt to attack their network and computer system the same way a hacker would. Ethical Hackers use the same techniques and tactics as those used by illegal hackers to breach corporate security systems. The end result is the company’s ability to prevent an intrusion before it ever occurs. A company can’t know if their security system is solid unless they test it. It’s hard, though, for a company’s IT team to thoroughly ring out the system. Try as they might, the techs can’t go at the system with all the malicious or mischievous motives of a true illegal hacker. To thoroughly uncover vulnerabilities, the theory goes; you must examine your security system through the eyes of an illegal hacker.

The word hacking has strongly negative connotations, and, for the most part, rightly so. But ethical hacking is much different. It takes place with the explicit permission of the company whose system is being attacked. In fact, their “good guy” role is underscored by the nickname “white hat” Ethical Hackers have been given. The nickname is a throwback to old Westerns where the good cowboys could be identified by their white hats.The company and the Ethical Hacker enter into a legally binding contract. The contract, sometimes called a “get out of jail free card,” sets forth the parameters of the testing. It’s called the “get out of jail free card” because it’s what harbors the Ethical Hacker from prosecution. Hacking is a felony, and a serious one at that. The terms of the agreement are what transform illegal behavior into a legal and legitimate occupation. Once the hacker has exhausted his attempts, he reports back to the company with a list of the vulnerabilities he uncovered. The list in and of itself, however, is not particularly useful. What’s most valuable is the instructions for eliminating the vulnerabilities that the Ethical Hacker provides.An Ethical Hacker works to uncover three key pieces of information. First, he determines what information an illegal hacker can gain access to. Next, he explores what an illegal hacker could do with that information once gained. Last, the Ethical Hacker ascertains whether an employee or staff member would be alerted to the break-in, successful or not.At first it might sound strange that a company would pay someone to try to break into their system. Ethical hacking, though, makes a lot of sense, and it is a concept companies have been employing for years. To test the effectiveness and quality of product, we subject it to the worst case scenario. The safety testing performed by car manufacturers is a good example. Current regulatory requirements including HIPAA, Sarbanes Oxley, and SB-1386 and BS 799 require a trusted third party to check that systems are secure.In order to get the most out of the assessment, a company should decide in advance the nature of the vulnerabilities they’re most concerned with. Specifically, the company should determine which information they want to keep protected and what they’re concerned would happen if the information was retrieved by an illegal hacker.Companies should thoroughly assess the qualifications and background of any Ethical Hacker they are considering hiring. This individual will be privy to highly sensitive information. Total honesty and integrity is of the utmost importance.

Broadband: What Next For Next-gen?

Broadband has been a huge success in the UK, with half of all UK homes now with access to a connection.But with a consumer call for a faster and more reliable service, and connection speeds falling behind countries like Japan and Sweden, suggested changes raised in a recent summit in London to discuss the future of broadband in the UK are still dividing opinion.

Plans for a future download speed of 24Mbps may seem fast for us, but with other countries around the world offering broadband deals, with connection speeds ranging from 40Mbps to even 100Mbps, could a change in infrastructure prove a turning point for broadband in the UK?

With the current broadband network based mostly on ADSL - a copper wire network designed to handle telephone calls – the demand for an increase in broadband speed could push the hardware to its limits. Other issues include noise on the line and falling connection speeds – causes for such disruption can include distance from the exchange and an increase in traffic on the network.
One of the issues facing any future plans for a fibre network in the UK would be ensuring that it would be open to all ISPs in much the same way as with LLU (Local Loop Unbundling) – which allows other cheap broadband providers the chance to put their services in BT telephone exchanges. But even getting to that stage has been a long and complicated process, and with the demand for more cheap broadband increasing each year – a change in infrastructure could been seen as a way forward and ensure that the UK is compatible with the ever-changing Internet. A new method of unbundling – known as sub-loop unbundling – could be necessary to the introduction of a fibre network, but would require operators to share space in street cabinets, which some believe to be unfeasible. There are also concerns that fibre networks would create another digital divide - much like the current scenario when it comes to rural broadband technology.Wireless solutions such as Wimax could be seen to be a temporary solution, but there has been a widespread call for more government funding to help the progression of UK broadband, particularly to those in remote areas of the UK. Fibre connections would provide opportunities for a faster connection that would be welcomed by online gamers, networks which share video content, as well as the chance of delivering high-definition content – such as HDTV – via a broadband connection.But with a number of problems still to be sorted within the existing broadband network – such as complications with ISP migration and actual connection speeds promised in broadband deals – the future of broadband in the UK remains an area of uncertainty.

Dial-up Internet Versus Dsl Internet -- A No-brainer When The Facts Are Known

Introducing The Twisted Pair

What's the difference between dial-up Internet service and DSL Internet service? While both systems use the telephone to access the Internet, that is where the similarities end. The differences include: utilization of capacity, speed and cost. Please continue reading as we explore in greater depth the differences between Dial-Up and DSL Internet.
To get a handle on the differences, it is important first to understand a little bit more about how the telephone system works. It all begins with a pair of copper wires or as is often called in the industry "twisted pairs", since the pair of wires are twisted around each other.

Each telephone connection requires one "twisted pair". The twisted pair handles all voice going out and coming into a handset. The twisted pair can also handle data, so long as the line is good and does not have any static or interference.

A standard dial-up Internet Service Provider (ISP) can provide their customers an access point to the Internet, but they have to rely on their customer's telephone service provider as the corridor to get the signal from the customer's computer to the ISP's modem (bridge to the Internet).

Most people who have ever used dial-up Internet have come to the conclusion that they can use their telephone for Voice as a telephone OR Data as a computer/fax line, but one cannot do both at the same time. A dial-up ISP can give their customers access to the Internet, but they do not have the equipment or capability to extend the use of the telephone line beyond this one kind of connection.

As a result, consumers who use dial-up Internet services have one line for the Internet connection, and if they are serious about keeping a line open for those who may wish to call them, they also have a second phone number installed to capture those incoming calls.

Introducing DSL Internet Services

DSL stands for Digital Subscriber Line. This means that digital packets of information are sent over one single channel and the voice information is sent over another channel, both of which "share" a single pair of wires. With DSL Internet services, one can actually use the telephone while using the Internet!

The key difference here is that the DSL Internet companies utilize a different kind of modem to connect their users to the Internet. You may have heard that DSL is not available in all areas, and this is true. The service relies on clear and strong signals from the client's computer to the local phone company's main access point to the Internet.

Once inside a client's home or office, the telephone system is still using the standard twisted pairs to carry the voice and data signals. But, the line that is intended to carry data signals has a filter on the line to reduce static noise in the line. Then, the line is connected to a DSL modem that intuitively knows how to distinguish the voice and data signals from each other.

DSL modems actually employ a trick to get the job done and it is very effective. A standard copper twisted pair of wires can carry up to 100 megabytes of data per second, but in order to be able to access the full potential of the twisted pair, one must have the correct hardware attached to the phone line.

A twisted pair is also able to carry signals of multiple frequencies at the same time. This is the trick of DSL Internet services. DSL services actually send voice through one frequency and data through another frequency (or channel). It is through this manipulation of frequencies that DSL Internet services are able to send two kinds of content over the same single twisted pair, thereby "sharing" one phone line between two tasks.

Put The Petal To The Metal

Dial-Up Internet Service Providers have hit a technological ceiling, preventing them from giving their users access to high-speed Internet access.

Dial-Up ISP's are limited by their technology. They are using the telephone lines to push an analog signal from their client's computer to their computer to gain access to the Internet. Analog's final frontier is the 56-kilobyte per second connection.

DSL Internet connections begin at 768-kilobyte per second (21 times faster than dial-up) and climb from there based on the consumer's willingness to pay for more speed and bandwidth.

56-kbps versus 768-kbps could mean the difference of downloading a music file or video in two minutes as opposed to forty-two minutes or longer. In some cases, files that take 24 hours to download on dial-up can be downloaded in just over an hour on DSL (think NetFlix movie downloads).

In Conclusion

For the average person on dial-up, they will generally have two phone lines, plus the $10-$20 per month subscription fee to their local ISP. DSL providers can provide DSL Internet for as little as $14.99 per month, plus the cost of one phone line.

When one considers the speed factor, DSL is a no-brainer. But when one also looks at cost, one has to ask themselves why they have been throwing money away all of these years on dial-up ISP's.

Beating Adware, The Sneakiest Software

Promoters of adware, software that shows advertising on a user`s computer, use some cunning tricks to get you to install their software on your machine. Here`s what to look out for.Adware is, by definition, something reasonable people don`t want on their computers. That`s why malware can`t just come out and ask people to install it. Often, the computer owner is completely unaware of it being installed. But not always.When adware doesn`t want to sneak in through an open window, it will try to trick you into letting it in through the front door. Don`t think you could be tricked? Don`t be so sure until you`ve checked out these most common ways people have been tricked into allowing malware to be installed on their machines.Adware Installation Trick 1: Piggybacking• How it works: malware may come bundled with a legitimate piece of software the user actually wants, such as a game or emoticon. The malware is merely labeled `companion software,` without any indication of what it will do.• How to fight it: be very suspicious of any software that comes bundled with other software. Don`t installed software that comes bundled with other software unless you know everything that the bundled software does. After all, if the bundled program has anything to do with the program you actually want, why couldn`t the software developer just get both programs` functionalities into a single piece of software? Software developers are now very sensitive to malware concerns and will provide a lengthy explanation of just why the bundled software is necessary, in the cases when they actually do need to use bundled software.Adware Installation Trick 2: Bait and Switch• How it works: since people are getting more and more suspicious of bundled software, the malware`s developers may simply label it as valuable software, for instance, a browser plugin that supposedly accelerates web browsing (but in reality only shows ads).• How to fight it: again, a suspicious mind is useful in avoiding malware. Ask yourself some questions:o What will this software actually do? Malware often comes with very fuzzy claims attached. Sure, it says it will improve your browsing experience, but how? Often, this improved browsing experience just means a browsing experience with more advertising.o If the software is so great, why is it being given away free? Most commonly, software is only given out free in two cases: if it`s OpenSource (designed by a community of developers and not proprietary--OpenSource software is always clearly labeled as such); or simply a come-on for a fuller-featured version of the software. If neither case is true, there`s a real chance the software is financed by adware.Adware Installation Trick 3: Outright Lying• How it works: malware may even be labeled as something else entirely, such as a well-known piece of software or a crucial component of the computer operating system.• How to fight it: this is the trickiest malware of all, and requires extreme caution. You don`t want to start deleting any of your program files, much less your system registry entries, unless you`re absolutely sure it`s malware. Plenty of overzealous parasite hunters have shot their own machines to bits this way. This is one case where you want to be using an anti-spyware program, and preferably a second anti-spyware program to provide a second opinion.Getting Rid of AdwareAdware is so tricky that trying to uninstall it by yourself could be like a trip into the Matrix. Luckily, there are good anti-spyware programs that tackle adware as well--after all many adware programs are also spyware since they monitor your internet usage.True, it may feel like adding insult to injury to have to install more software to get rid of software you never meant to install in the first place. But sometimes you just have to fight fire with fire.

Antivirus Software – Get The Bugs Before They Get You!

You turn on your computer, and it doesn’t look quite right. Maybe your icons have changed, or the background picture is wrong. Some options are disabled. Even worse, you may not be able to boot your computer up at all. Guess what – it’s probably got a virus.In today’s online world, protecting your computer from all the nasty things online is vital. Viruses can cause obvious issues, as described above, but they can also run silently in the background, propagating themselves across your computer and transferring on to the computers of people you know. Mostly, you only know you have a virus when substantial damage has already been done.Some common signs of a virus include:-Programs working erratically-Computer locks up-Greyed out options-The browser home page has changed-Icons have changed-Difficulties starting up the computerThere is a solution! Antivirus software is readily available, and the good ones are very efficient at dealing with viruses in all their many and varied mutations. Basically, if you’re online, you need this type of software.So which one do you choose? For starters, be careful of using something free off the internet, particularly if it’s one you’ve never heard of. Sometimes these programs are a way of implanting more viruses on your computer. Some of the better known brands give you the option of doing a free scan online, which is useful, but not a long term solution.It’s really important to choose well-known antivirus software. Ask friends, or someone computer savvy, for their recommendations. It may be worth visiting a computer store and buying it there, rather than online – after all, if they’ve gone to the trouble of stocking it, it’s most likely an established and trusted product.There are plenty of good brands available, far too numerous to list here, but some of the best known are from McAfee, Norton and Trend. Check out the support available to you – can you contact someone if you have trouble installing the software?Most importantly, make sure there’s an easy way to update the software on a regular basis (preferably as part of the purchase cost!). For example, my antivirus software pops up a little box every time an upgrade is available. I click okay, and it’s automatically downloaded to my computer. Viruses change and develop at an alarming rate, so it’s vital to keep your antivirus software up to date.Finally, the all-important backup! The word “backup” tends to produce the same glassy eyed response as the word “budget”, but it really is an essential part of being online. Regularly backup your important files to CD or DVD. If you’re a business user, an automated and frequent backup process is vital. Once a virus has destroyed your computer, it’s too late.Being online is wonderful, but don’t let it become a nightmare. Antivirus software will play a vital role in keeping your online experience a positive one.

Three Ways To Get Listed In Google

In this article I show you three ways to get listed in Google, including one method that is virtually guaranteed to work.
I'm constantly surprised by what I find when dealing with search engine optimization clients.
One of those "surprises" is coming across sites that aren't listed by Google, even though they have been live for many months.
For most Web sites, Google refers more traffic than any other search engine. So it's imperative that your site is indexed in Google.
As of September 09, 2003, Google claims to index Searching 3,307,998,701 web pages. Yet somehow sites still fail to make it into the Google index!
There are three simple methods to getting listed in Google, but only one of these is guaranteed... well almost. ;o)

1. Submit Direct To Google

The first method is to submit your web site via Google's free submit your site form. Just submit your home page and Google's crawler, Googlebot, will crawl the rest.
However, Google does not add all submitted URLs to their index, and there is no guarantee as to when, or if, your site will be indexed.

2. Get Linked From A Site That Google Crawls

The second method is to get a site that Google already crawls to link to your site. So when Google recrawls the web site, it will find the link to your site and crawl and index it as well.
This is Google's preferred method of finding sites to index.
To get another site to link to yours, simply look for a site that links to your competitors and ask them to link to yours. You may have to offer a link back to their site in exchange.
You may like to read my link popularity article, "How To Quickly Improve Your Link Popularity." In this article I show you how to find link exchange partners.

3. Submit Your Site To The Yahoo! Directory & The Open Directory Project Index

The third method is to submit your web site to the Yahoo! Directory and/or Open Directory Project index, which is owned by Netscape.
As far as I know, this is the only guaranteed method of getting into the Google index.
Google has agreements with Yahoo! and Netscape to include the sites indexed in their directories in the Google index. So submit your site to either, or both (recommended), of these directories.
For more information, visit Yahoo!'s How to Suggest Your Site page and the Open Directory Project's How to add a site to the Open Directory page.
Once your site is included in either of these directories, it will appear in the Google index in about 4 to 8 weeks.
So now you have no excuse for not getting indexed by Google.
