Calculate the checksum for the following input. Show your work.

1 1 0 0 1 1 0 0 1 1 0 0 1 1 0

1 0 1 0 1 0 1 0 1 0 1 0 1 0 1

Answer 1

Steps to calculate checksum

1. The data is divided into 8-bit segment

2. All the segments are added to get a result

3.If the result consists of extra bits more than 8-bit then extra bits are removed following steps 1 and 2.

4. Now take the the 1's complement to get checksum value

now we got checksum values for

1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 = 0 0 1 1 0 0 1 1

1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 = 0 1 0 1 0 1 0 1

the calculations are shown in page below
