What is the protocol? A few important protocols!


Did you heard the name of the protocol? Of course you have not heard the name of the protocol but you have used the internet and even still browsing the internet and reading this post but you don’t know about the protocol that connects you to the internet, no problem. In today’s article we will try to know more about the protocol and after that you will know about the protocol. There will be no problem.

Constantly we visit various websites starting from various websites to online news etc. through mobile phone connection and collect necessary information.

Protocol, which is used in digital communication. The protocol determines how data will be received and transmitted in the computer network. What connects your device to a browser through an internet connection can be simply called a protocol.

What is the protocol?

For digital communication, the process by which communication is carried out from one device to another over a network is called a protocol. You can call protocol the communication rules of data exchange that perform the process of web browser communicating with web server.

If the Internet has thousands of such protocols, one of the most popular protocols is https

Without protocol we cannot communicate over network. This is why the protocol is also called a digital language.

A few important protocol

  1. TCP: It stands for Transmission Control Protocol.

This protocol is called the mother of all protocols since it was first discovered.

TCP (Transmission Control Protocol) is the trusted medium for data transfer. The speed of data transfer in this medium is slower than UDP. TCP uses protocols that require high reliability.

TCP transfers data using three-label handshaking. The protocols used in this medium are HTTP, SSH, TELNET, FTP, HTTPS etc.

Transmission Control Protocol (TCP) is a standard that defines how a network communicates and maintains relationships through which applications can exchange data.

TCP works with Internet Protocol (IP), which tells us how computers send packets of data to each other. Together, TCP and IP are the basic rules that define the Internet. The Internet Engineering Task Force (IETF) defines TCP in Request for Comments (RFC) standards document number 793.

TCP performs the following functions:

  1. Determines how application data is fragmented into packets that networks can deliver. 2.Sends packets and receives packets from the network layer.
  2. Controls and directs flow.
  3. Accepts all incoming packets. In the Open Systems Interconnection (OSI) communication model, TCP covers part of Layer 4, the transport layer, and part of Layer 5, the session layer. When a web server sends an HTML file to a client, it uses Hypertext Transfer Protocol (HTTP) to do so. The HTTP program layer tells the TCP layer to set up the connection and send the file. The TCP stack divides the file into data packets, renumbers them, and then forwards them separately to the IP layer for delivery. Although each packet in a transmission has the same source and destination IP address, packets may be sent along multiple routes. The TCP program layer on the client computer waits until all packets have arrived. It then acknowledges what it receives and asks to retransmit what it doesn’t, based on the missing packet numbers. The TCP layer then assembles the packets into a file and delivers the file to the receiving application.

2. HTTPS is the photocopy that helps us to access a website https

The full form of https is Typertext Transfer Protocol Security (Hypertext Transfer Protocol Security). The secure version of http is https. HTTPS encrypts data transfer between websites to increase security. As a result, no one can read the data between the client and the server. Especially bank account email secure more important information https.

The https protocol uses an advanced SSL (secure sockets layer) certificate to transfer data between the browser and the server in an encrypted form.

3. FTP is a very popular protocol used for file transformation.

FTP stands for File Transfer Protocol. FTP is a standard protocol used to transfer files between computers and servers. Here you can have other devices like – mobile, tab, laptop, etc.

All these devices can download and upload files from an FTP server over a network using the FTP protocol.

FTP is a network protocol for transferring files between computers over a Transmission Control Protocol/Internet Protocol (TCP/IP) connection. Within the TCP/IP suite, FTP is considered an application layer protocol.

In an FTP transaction, the end user’s computer is usually called the Host. The second computer involved in FTP is a remote host, usually a server. Transferring files via FTP requires both computers to be connected via a network and properly configured.

Servers must be set up to run FTP services, and clients must have FTP software installed to access these services.

Although many files can be transferred using Hypertext Transfer Protocol (HTTP), another protocol in the TCP/IP suite, FTP is still used to transfer files behind the scenes for other applications such as banking services.

It is sometimes used to download new applications through a web browser.

4. SMTP: This protocol used for mail transfer stands for Simple Mail Transfer Protocol which is used to send mail.

SMTP (Simple Mail Transfer Protocol) is a network protocol (a set of rules for sending messages within a network) used to send and receive text-based messages or email messages between one server and another.

SMTP was first defined in 1982 by RFC 821, it was last updated by RFC 2008 with the Extended SMTP Addendum.

Some more SMTP full forms:

Small Mail Transfer Protocol

Send Mail to People

Simple Message Transmission Protocol (computing)

Source-Model Technique Package

Sub Manifest Transshipment Permit (India)
