Which component of an Operating System is responsible for managing the allocation of CPU time to different processes?
Memory Manager
File System
Scheduler
Device Driver
Scheduler
The Scheduler is the specific Operating System component responsible for process management by deciding which process in the ready queue is allocated to the CPU. It manages the transition of processes between various states such as Ready, Running, and Blocked to ensure optimal system performance.

The scheduler utilizes scheduling algorithms (like First-Come-First-Served, Round Robin, or Shortest Job First) to decide execution order. It maintains a ready queue and context switches between processes, saving the state of the current process in its Process Control Block (PCB) before loading the next one.
The scheduler acts as the brain of the CPU management sub-system.
Short-term schedulers manage the selection of processes from the ready queue for execution.
Context switching is the primary overhead associated with CPU scheduling.
Ensures fair distribution of CPU time among competing processes.
Maximizes system throughput and minimizes waiting time.
Excessive scheduling overhead can decrease overall system efficiency.
Complex algorithms increase the complexity of the kernel code.
General Purpose Operating Systems (Windows, Linux).
Real-time systems requiring deterministic scheduling (e.g., RTOS).
Option A (Memory Manager) handles RAM allocation and virtual memory mapping.
Option B (File System) manages data storage, retrieval, and organization on disks.
Option D (Device Driver) acts as a translator between the OS and hardware devices.
C is correct тАФ The Scheduler is the dedicated component responsible for CPU time allocation to processes.
Remember the hierarchy: Long-term scheduler manages process admission, Medium-term manages swapping, and Short-term (CPU scheduler) manages actual execution.
