Which of the following are broad functions of an operating system in computers?

Broad operating system functions include Statement 1 managing files and folders, Statement 3 acting as the interface between the user and the hardware, and Statement 4 helping application software run.

Statement 2 is not an operating system job because converting high-level language into low-level code is the work of a compiler or assembler.

The operating system organises storage into files and folders and controls access to them.

It sits between the user and the hardware, turning commands into hardware operations.

It also loads applications and allocates them memory and processor time.

Managing memory, processes, devices and security are further core duties of an operating system.
