Question 1
|
For the 8 – bit word 00111001, the check bits stored with it would be 0111. Suppose when the word is read from memory, the check bits are calculated to be 1101. What is the data word that was read from memory?

Question 1 Explanation:
Here, the check bits stored along with data are 0111 and the check bits calculated at receiver side are 1101. Both check bits are not same is the indication of error bit in data whose position can be calculated by performing the EX-OR operation.
So data bits are:
00011001
So data bits are:
00011001
Correct Answer: B
