What term describes the period of time allocated for a process to run in a preemptive multitasking system?

• A. Time-Slice
• B. Time-Quantum
• C. Execution Window
• D. Duration Limit

Answer: (A)

The term that accurately describes the period of time allocated for a process to run in a preemptive multitasking system is known as Time-Quantum. This term refers to the fixed amount of time that a process is allowed to execute before control is returned to the operating system to give other processes a chance to run. In preemptive multitasking systems, the operating system manages process execution by interrupting a currently running process once its time-quantum expires. This ensures that all processes receive a fair share of CPU time, promoting responsiveness and efficient CPU usage. The concept of time-quantum is fundamental to scheduling algorithms like Round Robin, where processes are cyclically given control of the CPU for their specified time-quantum. While "Time-Slice" is sometimes used interchangeably with time-quantum, it is more commonly understood to refer to a specific segment or partition of the time-quantum rather than the total time itself. "Execution Window" and "Duration Limit" are not standard terms used in the context of process scheduling and do not capture the essence of how process time allocation works in preemptive multitasking.
