Question: UDP and TCP use ones complement for their checksums. Suppose you have the following three 8-bit bytes: 11011010 10101000 11011011 What is the ones complement

UDP and TCP use ones complement for their checksums. 

Suppose you have the following three 8-bit bytes: 11011010 10101000 11011011 

What is the ones complement of the sum of these 8-bit bytes? 

Compute the ones complement of the sum of 10111011 and 11001100. Compute the ones complement of the sum of 10111011 and 00110101. 

Compute the ones complement of the sum of 11110011 and 11000001. 

Is it possible that a 1-bit error will go undetected with a ones complement checksum? 

Give an example of two separate 1-bit errors that will not be detected with a ones complement checksum.
