Computer network • It is possible to connect a number of computers and other electronic devices to form what is called a computer network. • The computers and devices which are part of the network can "talk" to each other and exchange information. In addition to the computers and devices which are connected, other devices are often needed for the network to operate properly. • Examples for such devices include hubs and switches. A network using one ...
