Network Design and Management

1.3. Overview of Network Protocols and Standards

Definition:
Protocols are rules governing data transmission in a network, while standards ensure interoperability among devices.

Key Protocols:

• Transmission Control Protocol/Internet Protocol (TCP/IP): Core protocols for internet communication.
• Hypertext Transfer Protocol (HTTP/HTTPS): Web browsing and secure data transfer.
• Simple Mail Transfer Protocol (SMTP): Email communication.
• File Transfer Protocol (FTP): File sharing.
• Domain Name System (DNS): Converts domain names into IP addresses.

Standards Organizations:

• Institute of Electrical and Electronics Engineers (IEEE): Defines hardware and software standards, e.g., IEEE 802.11 for Wi-Fi.
• International Organization for Standardization (ISO): Sets global standards like the OSI model.
• Internet Engineering Task Force (IETF): Develops internet standards and protocols.
