WebChecksum Algorithm. Take 2 binary input strings. Do their binary sum to find out the checksum which will be sent to the destination or to the receiver. In binary sum there are 6 cases:-. If both bits are 0 and carry is 0, sum=0 and carry=0. If both bits are 0 and carry is 1,sum=1 and carry=0. If both bits are 1 and carry is 0,sum=0 and carry=1.

WebQuestion 1. A. To calculate the checksum of the bytes 00110101 and 10101100, we add them in binary, discarding any overflow beyond 8 bits, and then take the complement of the sum. 00110101 + 10101100 = 11100001. Complement (11100001) = 00011110. Therefore, the checksum for the given bytes is 00011110.
