Two technicians are discussing the interface between system memory and the motherboard. Technician A says data errors caused by speed mismatches are handled by making the memory run a parity check for every bit accessed. Technician B says those speed mismatch errors are avoided by building time delays into the motherboard to allow the system to catch up to the memory. Which technician is correct? A. Neither B. Only Technician B C. Both
The correct answer is A. Neither.
Technician A's statement about using a parity check for every bit accessed to handle data errors caused by speed mismatches is incorrect. A parity check is a method used to detect errors, not correct them, by adding an extra bit (parity bit) to the data. It can only detect if an error has occurred, but it cannot fix the error.
Technician B's statement about avoiding speed mismatch errors by building time delays into the motherboard is also incorrect. Time delays, or slowing down the motherboard, would not resolve speed mismatch errors between the system memory and motherboard. Additionally, the motherboard's primary purpose is to provide physical connections and pathways for communication between different components of the computer, not specifically to address speed mismatch errors.
Therefore, neither technician is correct, and the correct answer is A. Neither.
