Which component of an OS provides basic control over computer peripherals?

• A. Kernel
• B. User Interface
• C. File System
• D. Hardware Abstraction Layer

Answer: (A)

The kernel is the part of the operating system that handles the actual control of hardware devices. It runs with high privileges and coordinates all resource management, including input/output operations. When software needs to talk to a peripheral, it makes a request to the kernel, which then uses device drivers to communicate with the hardware, handles interrupts from devices, and schedules data transfers. This is what gives the OS basic, consistent control over keyboards, disks, network cards, and other peripherals. The user interface is about how a user interacts with the system and doesn’t directly control hardware. The file system focuses on organizing and accessing stored data. The hardware abstraction layer provides a uniform way for software to interact with different hardware platforms, but it relies on the kernel to perform the actual device management and I/O operations.
