Understanding Common Network Protocols
Network protocols are the backbone of internet communications, facilitating the exchange of data between devices and systems. In this article, we'll delve into eight common network protocols that power the web: HTTP, HTTPS, FTP, TCP, IP, UDP, SMTP, and SSH.
HTTP (HyperText Transfer Protocol)
HTTP is the protocol that powers the web. It enables the transfer of hypertext (HTML files, images, etc.) between a client and a server. HTTP operates over TCP/IP and provides a set of rules for how requests and responses should be formatted and transmitted.

HTTPS (HyperText Transfer Protocol Secure)
HTTPS is an extension of HTTP that adds an extra layer of security by encrypting the data exchanged between the client and server. It is commonly used in online transactions and confidential communications.

FTP (File Transfer Protocol)
FTP is used for transferring files between computers on a network. It operates over TCP/IP and provides a way to move files reliably and efficiently.

TCP (Transmission Control Protocol)
TCP is one of the main protocols within the TCP/IP suite, designed for reliable, ordered, and error-checked delivery of data. It's used by many internet services like HTTP, FTP, and SMTP.

IP (Internet Protocol)
IP is the principal set of rules for sending and receiving data over the Internet. It provides the basic mechanism for routing packets of data from source to destination.

UDP (User Datagram Protocol)
UDP is a simpler, connectionless Internet protocol. Unlike TCP, it does not guarantee delivery, order, or error checking, making it faster but less reliable. It's commonly used in streaming services and online gaming.

SMTP (Simple Mail Transfer Protocol)
SMTP is the protocol used for sending emails. It operates over TCP/IP and provides a reliable mechanism for mail delivery between mail servers.

SSH (Secure Shell)
SSH is used for secure remote login and other secure network services. It provides strong encryption and authentication, replacing less secure access protocols like Telnet.
