Network Hardware

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