Work Step by Step

Greater throughput would be achieved by a system running two processes in a multiprogramming environment if one process were I/O-bound and the other were compute-bound. In a multiprogramming environment, the goal is to keep the CPU busy and avoid idle time. When one process is I/O-bound, it frequently needs to wait for input or output operations to complete, during which time the CPU can be utilized by another process. Meanwhile, a compute-bound process requires CPU resources to perform computations. By having one process that utilizes the CPU intensively and another that frequently releases the CPU due to I/O operations, the system can achieve higher overall throughput. This is because the CPU-bound process can fully utilize the CPU during its execution, while the I/O-bound process allows the CPU to be utilized by the other process during its waiting periods, maximizing the overall efficiency of resource utilization.
