 3.(a) What is minimum hamming distance? Why are redundant bits added by the sender? Name two error detecting methods.

3. (b) 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.

(b) A sender needs to send the four data items 0x1236, OXABCC, OX03BC, and 0XEEEE. To avoid confusion, Ox is written in the prefix to denote that the data is in Hexadecimal. For example, Ox3456 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.
