What is a router? What is the purpose of using a router?
A router is a device which controls the data transmission to and fro in a network. A router is one of the most important devices used in a network. It can be placed at gateways of an existing or new network. The routers keep the computers and other devices connected in a network with Internet. When a data is transmitted within a network or between two networks, router configures the data path. This is achieved by using headers and tables for obtaining the shortest path for data transmission to take place. Router is manufactured by different leading brands. The most leading ones are Linksys and D-Link. Different routers have different configurations. Routers are easy to set up and install. You can choose wired or wireless routers according to your office needs. The router is one of the critical devices in the field of communications and networking.

Using routers, you can encrypt the message sent and received using WEP.
