A router is a computing device that receives or forwards packets of data to or from the Internet in a process called routing. Routers are important components of computer networks that ensure that all transmitted data reaches its correct destination.
To illustrate, imagine that the Internet is your world and your computer is your home. Other computers connected to the Internet can be found in homes around the world. Suppose a household sends a letter to another household somewhere in the world. Does your letter have an address? And this address determines where the letter is addressed. But without reading the address, the letter will not reach the correct recipient. Also, without a medium, the letter will not reach its intended recipient. That medium is the courier. And the computer data courier is the router.
A router (broadband router) is also a device that allows two or more computers to receive data packets from the Internet at one of her IP addresses at the same time.
Note that your computer needs a different IP address than all other computers to connect to the Internet. Therefore, every computer connected to the Internet has its own IP address. It's like having your fingerprint or ID as an access card to access the internet. Due to the presence of routers, this "fingerprint" or "identity" can be shared by multiple computers at the same time.
In its simplest form, a router allows two or more computers to use the Internet simultaneously with one access path.

A computer with a cable modem can also be used as a router. Your computer runs the routing process like a regular router. Other computers are then connected to an Internet-connected computer that should be connected to the Internet. A computer with a cable modem has direct access to the Internet, and computers connected to it share the connection.
Why do you need a router?
For households that have more than one computer and require an Internet connection to each computer, subscribing to each computer can be a pain. The solution is to buy a router that allows all the computers in your home to connect to the internet. As defined above, a broadband router acts as a hub to your existing Internet connection. If my router is like a hub, will it affect my internet speed?
Please note that if one Internet connection is split, the connection speed will be affected. However, some broadband routers only minimally reduce internet speed, so the impact may not be significant.
Internet speed also depends on the types of applications used on your router. Some things, like online games, have little impact on speed, while others can make your connection so horribly slow that you can't use the Internet at all.
Offices typically use more sophisticated routers to redirect Internet connections to a large number of computers. These routers offer a better data package compared to common routers used in homes, thus improving internet speeds.
