8 Bit Bytes Complement in TCP and UDP Connections

Question

UDP and TCP use the 1s complement for their check sums. Suppose you have the following three 8-bit bytes: 10011001, 01010010, and 01011001.
a. What is the 1s complement of the sum of these 8-bit bytes? Show all your work.
b. Why is it that UDP takes the 1s complement of the sum; that is, why not just use the sum?
c. With the 1s complement scheme, how does the receiver detect errors?
d. Is it possible that a l-bit error will go undetected? How about a two-bit error? (Note that although UDP and TCP use 16-bit words to compute the checksum, for this problem you are being asked to consider 8-bit summands.)

Summary

The question belongs to Computer Science, particularly to Networking and it is about 8-bit bytes complement in TCP and UDP. The difference in complement of the sums has been given in the solution.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes

The tutors at HelpwithAssignment.com are totally in sync with what is required by me. So we are in a good place

I was having problem completing my economics assignment submission on the concept of demand and supply for my mid terms. That is when one of my friends suggested HelpwithAssignment.com and they got back to me as soon as I contacted them. I was very impressed by their expert econ tutors and they have been my guides since that time. The professors are happy with the crisp and relevant assignment work and I am happy with their indepth understanding and research for each assignment and timely delivery of assignments. Thank you HelpwithAssignment.!!!

Automata were definitely my problem area as far as computer science and programming assignments are concerned. However, after consulting the experts here everything was sorted out and my grades also improved. I will definitely thank the wonderful team of HwA to help me out during my crunch time.

Ben Bartlett Student

My dream of becoming a software engineer was made real by the programming assignment help experts of HwA. I completed by B. Tech last year from an university in Auckland and the experts knew exactly on how to proceed with all the programming solutions.

Sean Taylor Student

I needed a PowerPoint presentation with speaker notes to be submitted along with the assignment essay for my MBA Marketing class. I was facing a huge time crunch and desperately needed help with making an engaging PowerPoint presentation that would highlight the key aspects of my assignment essay and speaker notes that would help me open up the possibility of direct communication with the audience. When I sent the request to HwA with the requirements they assigned me a PowerPoint presentation expert with years of actual experience in preparing marketing presentations for his job. Needless to say I got an A in my assignment and topped the class.
