The internet is still quite a new development in technology, however it is impossible to think about life without it. It works in a very simple way. It takes information and sends it from one computer to another. It is not a difficult job, but it is a very big one. There are hundreds of millions of computers connected to the internet at the same time. However, they don’t all do the same thing. Some computers are like a digital box that store information, (like videos or music files) that people see, read or listen to. These stores of information are called servers, and there are three categories.
|
. The first type is a file server, which holds, ordinary documents. The second is a mail server for sending and receiving emails. The third is a web server for web pages. We know these servers store information but how do people find this information or send it to each other? For this, you need a client.
|
. A client is a computer that gets information from a server and delivers it to another computer. When you go online on your smartphone, you are using it as a client. When two computers on the internet exchange information, they are known as peers.
|
|
. Peer-to-peer (P2P) communication is when you send someone a photo on your smartphone. When that person sees this photo, your smartphone is working as the server. It stores the photo and the other person‘s device is the client, which searches for your information.
It then displays the photo on the other person's screen.
