What manages hardware and software, supports the computer's basic functions, and runs programs?

• A. Operating system
• B. BIOS
• C. Firmware
• D. CPU

Answer: (A)

The operating system coordinates hardware resources and runs software, providing the environment and services that let programs operate. It manages memory, schedules multiple programs to run without conflicts, handles input and output devices, and offers interfaces for users and applications. In short, it sits between applications and the hardware, enabling programs to start, run, and interact with the computer’s components. BIOS is firmware that runs at startup to initialize hardware and perform basic tests; it doesn’t manage plural programs or provide the ongoing environment needed for day-to-day software tasks. Firmware refers to embedded software stored in hardware components, not the broad system that runs applications. The CPU is the processor that executes instructions, but it needs the operating system to organize and manage how programs share time and resources.
