NETWORKING    

Basics of Networking : 

Network:    The Interconnection of two or more devices is called network.

Networking :   To enable the communication between two or more devices is called 

                         networking.

Need of Networking:-  

Ø  Speed:  We can retrieve the date from one system to another without wasting the time.

Ø  Resource sharing:  We can minimize the cost spent on resources by sharing the resources such as Printers, Fax, and Email Services etc.

Ø  Communication:  It helps in sending and receiving email messages which contains voice picture video and teleconferencing.

Ø  Backup fail over: It provides additional means of backup which are used if the original data is lost or corrupted.

Ø  It provides an improved communication between user ensuring that information is available to users.

Different types of Networking:-

LAN:   Local Area Network.

             A network which is established within a defined area is called LAN network.

              It operates within a limited geographical location and provides fulltime

              Connectivity to local services.

MAN:  Metropolitan Area Network.

              A Network which is established within the city only connecting different LAN’s.

              It provides full time and part-time connectivity.

WAN:   Wide Area Network.

                A Network which is established without any defined area like city – to – city,

                 State – state, country – country .It operates over a large geographical location

                  and provides fulltime and part-time connectivity.
