UDP and TCP use 1's complement for their checksums. Suppose you have the following three 8-bit bytes: 01010101, 01110000, 01001100. What is the 1's complement of the sum of these 8-bit bytes? (Note that although UDP and TCP use I6 bit words in computing the checksum, for this problem you are being asked to consider 8-bit summands). Show all work. Why it is that UDP takes the 1's complement of the sum; that is, why not just use the sum? With the 1's complement scheme, how does the receiver detect errors? Is it possible that a one-bit error will go undetected? How about a two-bit error?

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
