Suppose you have two 8-bit registers, A and B.
A contains the value 11001100
B contains the value 01001111
What is the decimal value of the two's complement binary sum?

UDP and TCP use 1s complement for their checksum. Suppose you have the following two 8-bit bytes: 0101, 1010. What is the 1s complement of the sum of these 8-bit bytes? Suppose the two bytes are altered during transmission with the checksum as follows: 1001, 0110. Can the checksum be used to detect the alteration?
