A sender needs to send the four data items 0x1236, 0xABCC, 0x03BC, and 0xEEEE. To avoid confusion, 0x is written in the prefix to denote that the data is in Hexadecimal. For example, 0x3456 is 3456 in hexadecimal. Now answer the following: i. Find the checksum at the sender site. ii. Find the checksum at the receiver site if there is no error . iii. Find the checksum at the receiver site if the second data item is changed to 0xABCE and the third data item is changed to 0x02BA.
