CNetwork or internet

DTransport

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 believe the correct answer is C) Network or internet, but I might be mixing it up with the OSI model terminology.

I’m a bit confused; I thought the Application layer dealt with protocols like HTTP, but I can’t recall where IP fits in.

I remember practicing a question about the layers of the TCP/IP model, and I think IP is definitely in the Network layer.

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