Computer Network Accessories

A network is two or more computers connected together. Computers in a network can communicate with each other. The Internet is also a type of network. A computer needs a network interface card to connect to a network.

            They usually need the following hardware in order to operate:

• A Network File Server is a dedicated computer that runs the software needed by the network and stores the files that users have created.
• Terminals are individual workstations that give access to the network. Using a terminal gives access to the network’s software and files.
• If a group of terminals share use of a printer then the system needs a Print Server. If two or more documents are sent to the printer at the same time the print server will put them into a queue. Users can then carry on with other work whilst waiting for the document to be printed.
• For the network to operate data needs to be sent to and from all parts of the network.
