What is computer networking

In the world of computers networking is the process of sharing data resources (document, printers) through linking certain computers devices together. It allows various computers or electronic communication. The connection can be through cables, telephones lines, radio waves, satellites or infrared light beans computers hardware and computer software both collaborate to create a network.

In several different ways network are categorized. One of those copes is described according to geographic area it is confined to:

Local Area Networking

A local area network (LAN) Is a network that generally span for small and limited area e.g. Single home, writing lab, small office building.

Wide area network

It confined relatively larges geographical areas. It connects and reaches to the networks across the cities, states or even across the globe. The world is largest public WAN is internet.

Servers

The connections of computers to a network are broadly categorized as serves or work- station. For providing services to other computers (and human users) server run continuously but generally they are not used directly by human. Services that servers provide include printing, software hosting, faxing, data storage, security for the networks resources and a lot more.

Basic servers

Networks vary due to their designs too. Basic two forms of network designs too. Basic two forms of networks design are termed as client/ server and peer to peer.

Client/server networks

in that kind of servers centralized server computers have the authority to store emails, web pages, files etc.

Peer to peer

those networks are in contrary to client server networks as each of pc in the network can communicate to the other without any centralized controlling pc.

Network topology

The layout and structure in terms of data flow is labeled as network topology. The flow of data varies in different networks. As in star networks all data flow through the centralized devices, whereas in bus network the communication and sharing of all computers is through one common conduit. Network topologies are categorized in common types that are bus, star, ring network and mesh networks.

Network protocol

Network protocol represents communication languages used by computer devices. This is another way of classification of computer networks. Each protocol supports specific application and networks usually implement multiple protocols. The most common protocols found on internet and home networks include TCP/IP.

Networks play crucial role in communication and data transmission and sharing organizations today. For the efficient usage of technology, computer networks are necessary. Furthermore computer networks assist computer users to access remote programmes and remote database. Those networks can accelerate the learning rate of any organization. So the importance of computer networks cannot be denied.
