What is a Computer Network?
A computer network consists of two or more computing devices connected to each other to share resources and information.
The network becomes a powerful tool when computers communicate and share resources (files, Peripherals such as printers, CD ROMS, Modems, Tape Backup drivers) with other computers on the same network or entirely distinct networks. At multiple places are connected with network people can send e-mail, share links to the global Internet, or video conferences to remote users.

Understanding Networking
Network - A set of computers connected together in a way that allows information to be exchanged between the computers.
Node – Any devices that is connected to the network. While a node is typically a computer, it can also be something like a printer…
Segment - Any section of a network that is divided, by a switch, bridge or router, from other section of the network.
Backbone - The major cabling of a network that all of the segments connect to. Typically, the backbone is capable of carrying more information than the individual segments. For example, each segment may have a transfer rate of 100 Mbps (megabits per second: 1 million bits a second), while the backbone may operate at 1 Gbps.
Topology - The way that each node is physically connected to the network.
Basic Networking Components
Most networks consist of at least two computers, network interface cards,Cabling, network operating system software, and a hub or switch.
