a) Consider the following small 4-byte header. Determine what the sender would enter in the 8-bit checksum field. Provide your answer in hex notation. Clearly show your work. 1 A8 10101000 10110011 11111 11 0x8A 0xB5 checksum 0x93 b) Provide your thoughts (briefly) on how accurate checksum is and why we would use this scheme based on your accuracy comments.

Step 1
A checksum is a simple error-detecting code designed to detect errors in data transmission or storage. An 8-bit checksum is calculated by summing the values of all bytes in a packet or data block, then taking the complement (inverting all the bits) of the final Show more…
