Chapter 4, Problem 17RTB

If 2 bits of a byte are in error when the byte is read from ECC memory, can ECC detect the error? Can it fix the error?

Explanation of Solution

Given:

2 bits of a byte are in error, when the byte is being read from an ECC memory.

To find:If an ECC can detect the error when the byte is being read from an ECC memory and a solution to fix it.

Solution:

The technology used for checking the errors is called as Error Correction Code which is used to identify and correct the internal computer data.

Yes, an ECC can detect the error in 2 bits of a byte, but the ECC cannot rectify it.
