Definition Of Computer Networking


June 21, 2018

A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.

An excellent example of a network is the Internet, which connects millions of people all over the world.The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. Two very common types of networks include: Local Area Network (LAN) Wide Area Network (WAN)

The term network topology describes the relationship of connected devices in terms of a geometric graph. Devices are represented as vertices, and their connections are represented as edges on the graph. It describes how many connections each device has, in what order, and it what sort of hierarchy.

Typical network configurations include the bus topology, mesh topology, ring topology, star topology, tree topology and hybrid topology.

Most home networks are configured in a tree topology that is connected to the Internet. Corporate networks often use tree topologies, but they typically incorporate star topologies and an Intranet.

First computer network

One of the first computer networks to use packet switching, ARPANET was developed in the mid-1960s and is considered to be the direct predecessor of the modern Internet. The first ARPANET message was sent on October 29, 1969.
