- A set of rules governing communication between computers on a network to ensure compatibility and data exchange.
- Network protocols and standards are essential for reliable communication between devices.
Types of Network Protocols
- FTP (File Transfer Protocol): enables file uploading and downloading between computers over the Internet.
- HTTP (Hyper Text Transfer Protocol): defines how web pages transfer information like documents, files, images, or videos between computers over the Internet.
- HTTPS (Hyper Text Transfer Protocol Secure): a secure version of HTTP, converting information into code to prevent unauthorized access; widely used by websites.
- TCP/IP (Transmission Control Protocol/Internet Protocol): routes information or messages from one end of a network to the other.
- SMTP (Simple Mail Transfer Protocol): an e-mail protocol for sending e-mail messages across the Internet.
- POP3 (Post Office Protocol Version 3): an Internet-standard protocol allowing e-mail clients to retrieve e-mail messages from an e-mail server.
- IMAP (Internet Message Access Protocol): an e-mail protocol storing e-mail messages on a mail server, allowing users to view, access, and manipulate messages on the mail server from their computer.
