Show Suggested Answer

Suggested Answer: C

The Network or Internet layer of the TCP/IP model is responsible for addressing, routing, and delivering packets across networks. The Internet Protocol (IP) operates at this layer, ensuring that data is correctly routed from the source to the destination.

Physical or network access layer deals with hardware transmission (e.g., Ethernet, Wi-Fi).

Application layer includes end-user services (e.g., HTTP, FTP).

Transport layer manages data flow using protocols like TCP and UDP but does not handle IP addressing.

I think the Internet Protocol is part of the Network layer, but I'm not entirely sure if it's called the Internet layer in the TCP/IP model.
