Router is a computer device that receives or sends data packets to and from the Internet to a destination in the call routing process. Router is an essential component of the computer network that allows all data sent to reach the correct destination.

As an example, imagine that the Internet is the world and is a home computer. Other computers connected through the Internet are households around the world. I gave a home address a letter to another house anywhere in the world. The letter is the right direction? And the address to determine the fate of the letter. But without reading the address, the letter did not come to the right receiver. The letter also would not be able to reach the intended recipient, if there is no middle. This medium would be the messenger. And the messenger of computer data is the router.

A router (broadband router) is also a device that allows two or more computers to receive Internet data packets to an IP address simultaneously.

Remember to connect to the Internet, a computer must have a unique IP address of the other teams. Therefore, each computer connected to the Internet has its own IP address. It's like having a fingerprint or ID as an access pass to enter the site. With the presence of the router, this "fingerprint" or "identification" could be shared by two or more computers simultaneously.

In simplest form, a router makes two or more computers using the Internet at the same time with an access pass.

One more thing: a computer with cable modem could also be considered as a router. In this sense, the team would make the process of routing like normal routers. Other devices connect to the computer with an Internet connection that would give access to the Internet. The team with the cable modem has the direct contact with the Internet and connected to it is sharing the connection.

Why would anyone need a router?

For households with two or more teams that want an Internet connection to all computers that are taking subscription for each would be too. The solution is to buy a router allowing every computer in the house to have an Internet connection. In the above definition, the broadband router to act as a hub for existing Internet connection.

If the router is comparable to a hub, which affects internet speed?

Keep in mind that once a single Internet connection is broken, the connection speed is affected. But there are some broadband routers that would bring minimal slowdown to the Internet speed and the effect might not even be big.

High Speed ??Internet also depends on the type of application used in a router. While some would inflict little effect on the speed like online games, other terribly that its slowdown, or even prevent you from using the Internet at all.

Usually, offices use a more sophisticated router to redirect Internet connections to the large number of computers. These routers would give better data packet, compared with a typical router used at home that results to faster Internet speed.
