Types of Network Hardware

Computer networks allow multiple computers to communicate with each other, share files and use a common Internet connection. Networks are common in businesses-- where a common set of files must be maintained--and are popular in homes with high-speed Internet connections. To function properly, networks need many different pieces of hardware.

Method

Networks can be set up as wireless, wired or hybrid. Hybrid networks utilize wireless radio transmission and Cat5 cables to transfer data.

Routers

Most networks use a router, which is a central piece of hardware that directs traffic on the network and routes it to the appropriate computer. Ad hoc (peer-to-peer) networks don't use routers.

Network Interface Card

Computers must have a network interface card, or NIC, to connect to the network. The NIC is responsible for sending data from the computer to the rest of the network.

Range Extenders

Wireless networks often require a range extender to increase the transmitting range of a wireless router.

Modem

To share a high-speed Internet connection, a router must be connected to a modem. The modem is usually provided by the ISP but can be purchased with other network hardware.
