What is Protocol?


The best way to describe a protocol is by comparing it to the way humans communicate. We have many languages in this world. If we did not have languages or a common way to speak how would we communicate?

A protocol is similar in that it is there to decide how data is transferred over the network, how it is formatted and so on so computers and servers have a standardised way to communicate with each other.

So you can see protocols like a set of rules that determine how clients and servers will communicate with each other.

One of the most common and known protocol example is HTTP, that is used over the world wide web. HTTP is an application-layer protocol used for transferring files on the internet. It is used by web browsers and servers to communicate.
