Computer network

systems of several computers which are connected to one another by cables

Computer networks may be classified according to the network layer at which they operate according to some basic reference models that are considered to be standards in the industry such as the seven layer OSI reference model and the four layer  Internet Protocol Suite model. In practice, the great majority of networks use the Internet Protocol (IP) as their network layer. Some networks, however, are using IP Version 6 IPv6, usually in coexistence with IPv4. IPv6 use is often experimental. It is an interconnection of a group of computers in other words.
