Network Protocol

 Network Protocol

A network protocol is a set of rules that governs the interconnection, communication, and exchange of data between computers and other devices on a network.

NCP (Network Control Protocol) was the first network protocol used for communication between computers on early computer networks. Later, it was replaced by TCP/IP, which is now the standard protocol used on the Internet.

1. TCP/IP (Transmission Control Protocol/Internet Protocol)

TCP/IP is the standard network protocol used for communication over the Internet. It ensures that data is transmitted reliably and reaches the correct destination.

2. HTTP (HyperText Transfer Protocol)

HTTP is a network protocol used to transfer web pages and other web resources between a web server and a web browser on the World Wide Web (WWW).

3. HTTPS (HyperText Transfer Protocol Secure)

HTTPS is the secure version of HTTP that encrypts data exchanged between a web browser and a web server to provide safe and secure communication.

4. DHCP (Dynamic Host Configuration Protocol)

DHCP is a network protocol that automatically assigns IP addresses and other network configuration settings to devices connected to a network.

5. SMTP (Simple Mail Transfer Protocol)

SMTP is a network protocol used to send e-mails over the Internet.

6. FTP (File Transfer Protocol)

FTP is a network protocol used to transfer files between computers over a network or the Internet.

Example: Uploading website files to a web server.

POP (Post Office Protocol)

POP is a network protocol used to receive and download e-mails from a mail server to a user's device.
