Web Protocols
The proper operation of the Internet depends on a verity of protocols. Simply said, a protocol is a set rules that allows two locations on a network to connect, communicate, and transfer data. Several of the most important internet data transfer protocols are listed here.
TCP/IP
The Traffic Control, or TCP/IP, protocols are used to manage Internet transmission. It enables communication between various computer and computer types over networks. Many computers of every size and shape are connected by an Internet that uses TCP/IP as a single. Internally, the internet is a network of separate physical network (like LANs). Joined by network connector hardware. The topology of a potential Internet is seen in the illustration. The letters A, B, C, and others here stand in for stations. A computer is a station in TCP/IP. Routers gateways are shown in the figure by the solid circles with the numbers 1, 2, 3, etc. Roman numerals I, II, III, and so forth are represented by larger race tracks that stand in for various physical networks.
HTTP
Data on the web is mostly accessed using the Hyper Text Transfer Protocol. A collection of rules for creating and transferring webpage data (text, photos, videos, and multimedia files) over the internet is known as HTTP, which is a server and client communication protocol that enables communication between web servers and users of the internet. The TCP/IP protocol series is built on top of HTTP, an application layer protocol.
HTTPS
Hyper transfer Protocol over secure Socket Layer is known as HTTPS. Consider it an HTTP version with security. Most websites that request sensitive or personal data do so via HTTPS (such as a password or your credit card details). SSL is used when yow view a website using HTTPS (Secure Socket Layer). An SSL
Certificate must be loaded on the server for a website to use HTTPS. These are typically issued by a certificate Authority, which is a reputable third party (CA).

FTP
Files Transfer Protocol is known to as FTP. It is used for online file transfers. Web developers frequently use FTP to upload updates to a website (i.e. to upload a new version of the website). FTP is used to simply transmit the file from one computer to a specific location on another computer, as opposed to HTTP which uses it to display the file in your browser. The files can be sent using FTP from your computer to a distant computer (like a web server) or from the distant computer to your local computer.
SMTP
Simple Mail Transfer Protocol is known as SMTP. It describes how computers exchange electronic mail using the TCP/IP protocol. It complies with postal rules (POP). Only computers that are constantly connected to the internet, such as Internet Service Providers (ISP), can use SMTP to receive mail. SMTP is used to upload message straight from the client to an intermediate server. After that, the users to whom they offer Internet access receive the message from the ISP servers.
