Question Question 1
Assertion. A computer can deliver performance only through an efficient combination of hardware and software.
Reason. While hardware refers to the physical electronics equipment, software are the recorded programs that govern the hardware to perform tasks in a computer.
(a)
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Explanation
If the hardware is inefficient, the best optimized software will also perform poorly on it and a poor software can degrade the performance of the best most efficient hardware. Hence, both need to be efficient for the computer to deliver best performance.
