Expert Solution

Introduction:

Checksum is a technique used to verify the integrity of data transmitted over a network. The Internet Checksum Algorithm is a widely used algorithm to compute the checksum for a given set of data. It works by calculating the sum of all the 16-bit words in the data, and then taking the one's complement of the sum.

To compute the internet checksum of a sequence of 16-bit words, we follow these steps:

Add up all the 16-bit words, discarding any overflow bits.
Take the one's complement of the result obtained in step 1.
The result obtained in step 2 is the checksum.
