Question

Which of the following is not a valid address in an internet employing the TCP/IP protocols ?

• A. Frame address
• B. Physical address
• C. Logical address
• D. Port address

Hint:

Remember the layers: MAC = Hardware (Link), IP = Logical (Network), Port = Software (Transport). "Frame" describes the container, not the address itself.

Answer 1

The Correct Option is A

In the TCP/IP protocol suite, several types of addresses are used to ensure data reaches the correct destination across different layers of the OSI and TCP/IP models. 1. Recognized Addresses in TCP/IP:
• Physical Address: Also known as the MAC (Media Access Control) address, it operates at the Data Link Layer to identify a specific network interface on a local segment.
• Logical Address: This refers to the IP (Internet Protocol) address (IPv4 or IPv6) used at the Network Layer to identify a host globally across the internet.
• Port Address: Used at the Transport Layer (TCP/UDP) to identify a specific process or service running on a host (e.g., port 80 for HTTP). 2. Identifying the Invalid Address: A "Frame address" is not a standard term for an address type in the TCP/IP suite. While data at the Data Link Layer is encapsulated into "frames," the addressing used within those frames is the Physical (MAC) address. 3. Conclusion: Because Physical, Logical, and Port addresses are the three fundamental tiers of addressing in an internet environment, "Frame address" is the odd one out and not a valid classification.
