What is process interleaving?

Process interleaving is a technique used in multitasking operating systems where multiple processes are executed in overlapping time periods. Instead of executing one process to completion before starting another, the CPU switches between processes, allowing each to run intermittently. This approach enhances system responsiveness and resource utilization, as it enables the system to handle multiple tasks simultaneously, even if only one process is actively using the CPU at any given moment. Interleaving is essential for managing concurrent processes effectively, particularly in environments with limited resources.
