Network Protocol

What are network protocols?

Network protocols are rules for devices to communicate. They enable global connectivity within the same network. In simple terms, they're like a universal language, allowing diverse devices to communicate securely.

How do network protocols work?

Network protocols divide complex operations into smaller tasks and functions, enabling seamless communication among connected devices within a network. These protocols define rules for collaboration across all network levels to ensure effective and secure data exchange. This collaboration follows a structured approach, often adhering to models like the Open Systems Interconnection (OSI) model, which outlines specific aspects of the network communication process within each layer.

What are the most common types of network protocols?

• TCP/IP (Transmission Control Protocol/Internet Protocol) - The foundational suite of protocols that powers the Internet, handling data transmission and routing.
• HTTP (HyperText Transfer Protocol) - Used for transmitting web pages over the Internet.
• HTTPS (HyperText Transfer Protocol Secure) - A secure version of HTTP that encrypts data for secure online transactions.
• FTP (File Transfer Protocol) - Used for transferring files between computers on a network.
• SMTP (Simple Mail Transfer Protocol) - Enables sending and routing emails between mail servers.
• DNS (Domain Name System) - Translates domain names into IP addresses, enabling browsers to load internet resources.
• SSH (Secure Shell) - Provides a secure channel over an unsecured network, typically used for remote login and command execution.
• UDP (User Datagram Protocol) - Facilitates time-sensitive transmissions like video playback or gaming, where speed is prioritized over error correction.
