Computer Network Accessories, often simply referred to as a network, is a collection of computers and devices interconnected by communications channels that facilitate communications among users and allows users to share resources. Networks may be classified according to a wide variety of characteristics. A computer network allows sharing of resources and information among interconnected devices.
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.
