Can u do all the question just the answers thank you

3. In the five-layer networking model, data sent to the physical layer consists of the application data, data link layer header, data link layer trailer, network layer header, and transport layer header. In the diagram of data sent to the physical layer below, label each part using one of the terms above. (Order matters.) 4. Which layer of the TCP/IP five layer model does each of the following? a. Uses a MAC address b. Uses an IP address c. Uses a port number to identify a process d. Provides host-to-host communication e. Sends signals through media f. Transmits information across a local area network g. Transmits information through a router between networks h. Provides process-to-process communication i. Interacts with the user 5. What unit is created at each layer? The choices are frame, packet, or segment. a. Layer 2 Data Link layer b. Layer 3-Network layer c. Layer 4 Transport layer 6. Recall that many protocols for layers 3, 4 and 5 of the layered model are called Requests for Comments (RFCs) and are published by the Internet Engineering Task Force. Go to http://www.rfc-editor.org to look at a Requests for Comment and answer the question below. The question is just to make sure you found the RFC - don't worry if you don't completely understand the RFC. Look up RFC 791, Internet Protocol (IP). Go to section 3.1 and look at the diagram of the IP header. List each field in the header. (You do not have to explain them, just list them).
