What is ISP?

ISP: It is a company that provides the Internet connections to the users. There are many ISP companies in each big city of each country of the world. You have to get an Internet connection from any ISP company of your local city to connect to the Internet.


ISPs then connect to larger ISPs, and the largest ISPs maintain fiber-optic “backbones’ for an entire region. Backbones around the world are connected through fiber-optic lines, under Sea cables or satellite links. In this way, every computer on the Internet is connected to every -other computer on the Internet. The figure is shown below that shows how an Internet works.
