parts of the computer system and also helps users understand

the results produced by the computer. Some of the most Operating Systems

Apple macOS and Linux.

Without an operating system, a computer cannot function and users will not be able
to run programs because the operating system controls and coordinates the activities

of both software and hardware. The operating system acts as an interface between
the computer and the user, facilitating communication in both directions. It ensures
that tasks are performed effectively and without unnecessary delay by managing

interactions between the various components of the computer.
