Basics Of A Router |
Page 1 of 2 Router is a computer device that receives or forwards data packets to
and from the Internet towards a destination in the process called
routing. Router is the essential component of the computer networking
that enables any sent data to arrive at the right destination.
As an illustration, imagine that the Internet is the world and one
computer is one household. Other computers connected through the
Internet are households around the world. Say one household will send a
letter to another household in any part of the world. The letter has an
address right? And that address would determine the destination of the
letter. But without one reading the address, the letter would not
arrive to the right receiver. The letter also would not be able to
reach the intended receiver if there is not medium. This medium would
be the courier. And the courier of the computer data is the router.A router (broadband router) is also a device that enables two or more computer to receive data packets from the Internet under one IP address at the same time. Remember that to be able to connect to the Internet, a computer must have an IP address unique from the rest of the computers. Therefore, every computer connected to the Internet has it own IP address. It is like having a fingerprint or ID as an access pass to be able to enter the web. With the presence of the router, this “fingerprint” or “ID” could be shared by two or more computer at the same time. In simplest form, a router makes two or more computer use the Internet at the same with one access pass. One more thing: a computer with cable modem could also be considered as a router. In this, the computer would do the process of routing like normal routers do. Other computers are then connected to the computer with Internet connection that would give it with the Internet connection. The computer with cable modem has the direct contact with the Internet and the ones connected to it are sharing the connection. |
