Explanation:
Detailed explanation-1: -A message 1001 1100 1010 0011 is transmitted using the Internet Checksum (using 4-bit words). What is the value of the checksum? Answer: Adding the 4-bit words yields 1001 + 1100 + 1010 + 0011 = 100010.
Detailed explanation-2: -A checksum is a value that represents the number of bits in a transmission message and is used by IT professionals to detect high-level errors within data transmissions. Prior to transmission, every piece of data or file can be assigned a checksum value after running a cryptographic hash function.
