___ is a function of the UDP checksum fieldSelect one:a. Error detectionb. Congestion avoidancec. Flow controld. Fragmentation

For which fields is the UDP checksum calculated? Why?

The Internet checksum, used by IP, TCP and UDP, is formed by taking the ________ of the 16-bit words of the message:Question 14Select one:a.two’s complement sumb.one’s complement sumc.logical XORd.logical ORe.logical AND

Assume that the UDP system on your computer received a datagram whose header contains Source Port #9568, Dest Port #21932, Length of 12, and a payload containing 0x9CBD 0x0085. What value should be in the checksum field?Group of answer choices0001100001011011100111010100001011100111101001000001100001011011

The UDP 16-bit Internet checksum on the data can be disabled by setting the checksum field to:Question 19Select one:a.all 0 bitsb.-1c.0xffffd.65535

Given the segment header below of a transport protocol along with the following checksum definition that is computed and then stored before every segment is sent to a receiver: Treat the Source_port, Destination_port and Length fields as 8 bit numbersAdd the Source port to the Destination port to obtain Result_1Add Result_1 to the Length field to obtain Result_2Take the 1’s complement of Result_2 and put the 8 bit value in the Checksum field   <----1 byte---->   <----1 byte---->Source_port Destination_portLength Checksum Compute the value that will be put in the Checksum file for the segment below. Show your work and the final Checksum value. 0011 01000110 10000001 0010
