HTTP, FTP, and SMTP are three different network protocols used to transfer information over the internet:



What I mean by HTTP

HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting data between a web server and a web browser. It is the foundation of data communication for the World Wide Web and is used to retrieve resources such as HTML documents, images, and other files from web servers. It works on the application layer of the OSI (Open Systems Interconnection) model and typically uses TCP/IP (Transmission Control Protocol/Internet Protocol) as its transport layer.


Let's have a look at FTP

FTP (File Transfer Protocol) is a protocol used for transferring files over the internet. It allows users to upload and download files from an FTP server using an FTP client software. It is commonly used to exchange files between computers, such as transferring files from a personal computer to a web server. FTP works on the application layer of the OSI model and uses TCP/IP as its transport layer.


What's SMTP mean

SMTP (Simple Mail Transfer Protocol) is the protocol used for sending email messages over the internet. It is responsible for transferring email messages between servers, as well as between a server and a client email program. SMTP works on the application layer of the OSI model and uses TCP/IP as its transport layer.
