Question

What is the primary function of an operating system?

• A. To compile source code
• B. To manage hardware and software resources
• C. To design user interfaces
• D. To execute database queries

Hint:

An operating system manages the computer's resources, ensuring the efficient operation of hardware and software.

Answer 1

The Correct Option is B

The core role of an operating system is to orchestrate hardware and software assets. This involves several key operations:

• Resource Assignment: The OS allocates critical resources like CPU cycles, memory, and I/O devices among programs and users.
• Memory Administration: It meticulously tracks every memory byte to manage its allocation and release efficiently.
• Process Synchronization: It governs processes and supervises application execution by ensuring a stable environment with proper assignment and prioritization of all hardware and software resources.
• Peripheral Control: The OS manages external devices through drivers, enabling communication between hardware and software components.
• User Interaction Layer: It offers a bridge between users and the computer's hardware, simplifying interaction and command.

Conversely, activities such as source code compilation, user interface design, and database query execution are typically domain-specific functions of application software or development tools, not primary operating system duties.
