A network consists of two or more computers that are
linked in order to share resources (such as printers and CDs), exchange files,
or allow electronic communications. Two very common types of networks include:
Local Area Network (LAN) Wide
Area Network (WAN).
Basic computer network components. Computer networks share common
devices, functions, and features including servers, clients, transmission
media, shared data, shared printers and other hardware and software resources, network interface card(NIC), local operating system(LOS), and
the network operating
system (NOS).
A computer networking
is a digital telecommunications network for sharing resources between nodes,
which are computing devices that use a common telecommunications technology.
Data transmission between nodes is supported over data links consisting of
physical cable media, such as twisted pair or fibre-optic cables, or by
wireless methods, such as Wi-Fi, microwave transmission, or free-space optical
communication.
Computer networks are
the basis of communication in IT. They are used in a huge variety of ways and
can include many different types of network. A computer network is a set of
computers that are connected together so that they can share information.
