Question
Multiprogramming -------------------- idle time of CPU and --------------------- throughput of the systemSelect one:a. decreases, decreasesb. increases, increasesc. increases, decreasesd. decreases, increases
Solution
The correct answer is d. decreases, increases.
Multiprogramming is a method used to execute multiple programs on a single processor machine. It decreases the idle time of CPU because while one program is waiting for I/O processing, the CPU can switch to another program. This ensures that the CPU is always busy and not sitting idle.
On the other hand, it increases the throughput of the system. Throughput refers to the number of processes that are completed in a given amount of time. Since multiple programs are being executed simultaneously, more processes are completed in less time, thereby increasing the throughput.
