Networks

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices pass data to each other along network links (data connections). Data is transferred in the form of packets. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.

There are many companies which design, manufacture and sell networking equipment i.e. Cisco systems, Juniper Networks, HP, D-Link, Netgear etc. But we are going to cover Cisco devices in our website because Cisco is the leader in network equipment manufacturing and they have a very huge customer base all over the world. Cisco offers best equipment ranging from small business to enterprise class.
