Which layer of the TCP/IP model includes the Internet Protocol (IP)?

APhysical or network access

BApplication

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.

Haha, who would even consider B) Application? That's like saying the internet runs on cat videos and memes. C) is the way to go.

C) Network or internet. Easy peasy. Now, if only the rest of the exam questions were this straightforward.

Definitely C. I can't believe anyone would think IP is in the physical or application layer. That's just silly.

C) Network or internet is the correct answer. The Internet Protocol (IP) is part of the network layer in the TCP/IP model.

I feel like I’ve seen this before, but I’m torn between C and D. I just can’t recall if IP is specifically mentioned in the Network layer.

I’m a bit confused because I thought the Transport layer dealt with protocols like TCP and UDP. Does that mean IP is definitely in the Network layer?

I remember practicing a question like this, and I think the correct answer is C) Network or internet. It makes sense since IP is all about routing.

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.

Ah, the TCP/IP layers - I remember learning about this. Let me think it through... IP has to do with routing and addressing, so it makes sense that it would be in the network layer. I'll go with C.

This is a straightforward question if you know the TCP/IP model well. The network layer is where IP resides, so I'm confidently selecting C) Network or internet.

The network layer is where I'd expect to find IP, so that's my best guess. But I'm not 100% certain, so I'll double-check my notes before answering.

Hmm, I'm a bit confused on this one. I know IP is a key protocol, but I'm not sure which layer it's part of. I'll have to think this through carefully.
