Which of the following are the main functions of an operating system? (Choose two.)

Text processing is a function of specific application software (e.g., word processors), not a core function of the operating system itself.

Program compilation is handled by compilers, which are development tools, not a direct function of the operating system.

Web browsing is performed by web browser applications, not the operating system's core function.

Operating systems are responsible for managing the execution of applications, including loading them into memory, scheduling their execution, and allocating resources, ensuring they run efficiently and without conflicts. This is known as process or application management.

Flowchart editing is a function of specialized design software, not a fundamental operating system task.

Operating systems provide an abstraction layer between hardware and applications, controlling and mediating access to resources like CPU, memory, storage, and peripherals. This hardware access control ensures fair usage, prevents conflicts, and protects system integrity.
