About Routers

There are a number of ways to define router. Router can be defined as a device, or in some cases a software in your computer, that forwards data packets from one network to another. Router can also be defined as a network device responsible for determining the next network point to which a packet should be forwarded towards its destination. The role performed by the routers is very important in your home or office networks especially from the security and data transfer point of view. It will not be wrong to say that routers are the heart of your home or office network.
 

Router is an integral device for your home or office network. As stated earlier router is a device responsible for sending data packets from one network to another. In order to decide the best path for forwarding the packets, routers use headers and forwarding tables. In simple words we can say that the existence of your home or office network is simply impossible without a router. In the beginning routers were called gateways mainly because they are located at the places where two or more networks connect.
