What is done by the industry to reduce buffer delay in streaming media. Please discuss 3 ways how minimizing buffer delay can be achieved.
UDP uses 1's complement for its checksums. Suppose you have the following three 16-bit words0100010001000100, 0101010101010101, 0011001100110011. What is the 1's complement of the sum of these 16-bit words? Why is it that UDP takes 1's complement of the sum; that is why not just use the sum? With 1's complement scheme, how does

Several techniques (typically referred to as forward error correction) can be used to add redundant bits to a message in order to help a receiver correct bits that have been damaged in transmission. One simple technique combines row-based (character) parity with column-based (longitudinal) parity to help detect and correct s
