The Transport layer in the TCP/IP model includes the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). UDP is a connectionless protocol used for fast, lightweight data transmission where reliability is not the priority (e.g., video streaming, VoIP).
Application layer handles end-user services but not transport mechanisms.
Network or internet layer deals with IP addressing and routing, not UDP.
Physical or network access layer concerns hardware transmission methods.

I was torn between A and D, but D makes more sense.

I think it's D) Transport. UDP is part of that layer.

I definitely recall that UDP is not in the Physical layer, so it must be either Application or Transport.

I’m a bit confused; I thought UDP was in the Application layer, but now I’m leaning towards Transport.

I remember practicing a question about TCP and UDP, and I think both are in the same layer.

I think UDP is part of the Transport layer, but I’m not completely sure.
