WebMar 30, 2024 · Unlike checksum scheme, which is based on addition, CRC is based on binary division. In CRC, a sequence of redundant bits, called cyclic redundancy check bits, are appended to the end of data unit so that the resulting data unit becomes exactly divisible by a second, predetermined binary number. WebSolution-. We apply the above discussed algorithm to calculate the checksum. 1001001110010011 + 1001100001001101 = 10010101111100000. Since, the result consists of 17 bits, so 1 bit is wrapped around and added to the result. 0010101111100000 + 1 = 0010101111100001. Now, result consists of 16 bits.
