Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol.Ĭomputer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanisms, and organizational intent. Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment.

They are identified by network addresses and may have hostnames.

The nodes of a computer network can include personal computers, servers, networking hardware, or other specialized or general-purpose hosts. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. Computers use common communication protocols over digital interconnections to communicate with each other. A computer network is a set of computers sharing resources located on or provided by network nodes.
