Hello, I need help with two Tasks for Data Communication

Task 1:

Task 2:

Note: In Task 1, Figure 2, point (1) can be skipped, so only (3), (4) and (6).

I already got an answer to this question, but forgot to mention that in Task 1, Figure 2 point (1) needed to be skipped as my Lecturer said we don't have to do i

I have to submit this via PDF or Word file.

Looking forward to your reply. I will need to scan it afterwards and attach it in Word. So, I hope you can help me and do those 2 Tasks for me and please read the 'Note' I've written above about Task 1, Figure 2 where you can skip point (1) and only do the other three, (3), (4) and (6).

Thank you for your help!!!

Assessment Task 1 Task 1: Link Layer (and network layer) addressing and forwarding a) Consider the figures below. The IP and MAC addresses are shown for nodes A, B, C and D, as well as for the router's interfaces.

Give the source and destination Ethernet addresses, as well as the source and destination addresses of the IP datagram encapsulated within the Ethernet frame at points (1), (3),(4), and (6) in the figure above. Task 2: Error Detection and Correction: Cyclic Redundancy Check Consider the Cyclic Redundancy Check (CRC) example shown in your lecture. Suppose that the 4-bit generator (G) is 1001, that the data payload (D) is 10011111 and that r=3. a) What are the CRC bits (R) associated with the data payload of D = 10011111, given that r=3? b) Add the obtained CRC bits with the payload and check whether the receiver has detected an error or not?
