What is Protocol? How many types of protocols are there?

What is Protocol?

Hello friends, what is a VPN for you? You must know about it, but do you know what is Protocol, and how it works? Or what is it used for? So today we are going to tell you about the protocol.

Friends Protocol is a kind of digital rule, which is used in digital communication. The protocol itself decides how the data will be transmitted over the computer network and how the data is received. Protocol in computing is also called digital language. Without these, we cannot connect to the internet, nor can we transfer data from one computer to another. Any file or mail sent by us on the Internet reaches with the help of this protocol, and we can use the Internet.

How does the protocol work?

Each network protocol operates on rules for how its data packets should be organized. Because protocols such as the Internet Protocol often work together in layers, some of the data embedded inside a packet formatted for one protocol may be in the format of some other related protocol (named encapsulation).

Each protocol has its different methods, with the help of which it is decided what is its work? How will it send and receive information? If there is an error in all this, then how will he manage it? The protocol helps to connect two devices and transmit data, how the data should go from one device and how to receive the data to the other device, decides the protocol itself, and this is how the protocol works.

Connecting different hardware to the network and sharing information and giving instructions between them is a very difficult task, for this, it is necessary that both the sender and the receiver communicate in the same language and this work is possible only by protocol.

How many types of protocols are there?

Have you come to know what is the protocol? But do you know that there are many types of protocols as well? So let us know how many types of protocols are there?

1. TCP- Transmission Control Protocol:–

TCP and IP both follow different processes, but they can also be used together and when any two or more protocols are used for the same task then it is called a stack. Because they have some layer of operation. If seen, both these protocols are used to represent a complete suite and this suite of protocols transmits information about the operation of the web. TCP and IP protocols are also used for many local area networks.

2. FTP- File Transfer Protocol:-

The full form of FTP is File Transfer Protocol. As the name suggests, it is used to transfer files from one computer to another. FTP is a type of protocol that sets some rules for the exchange of files between two systems.

3. HTTP- Hyper Text Transfer Protocol:-

The full name of HTTP is Hyper Text Transfer Protocol which is an application protocol. Any data from the Internet reaches our computer from the server to our browser in the HTTP language itself, which the browser translates into its original language so that we can easily read it in our language.

4. SMTP- Simple Mail Transfer Protocol:-

By using the SMTP protocol, we send our email from one place to another, with SMTP there are two more protocols used, namely “POP (Post Office Protocol)” and “IMAP (Internet Message Access Protocol)”. All these protocols work with the help of TCP / IP and PORT25 works between them.

There are many other protocols, but they are not used much, you can see the list of other protocols below.

• IGRP (Interior Gateway Routing Protocol)
• EIGRP (Enhanced Interior Gateway Routing Protocol)
• RIP (Routing Information Protocol)
• RTMP (Real-Time Messaging Protocol)
• HTTPS (HyperText Transfer Protocol over Secure Socket Layer)
