For developers and advanced users, most operating systems also offer a command-line interface (CLI) that allows for precise control and automation through text-based commands. This is most commonly a graphical user interface (GUI), featuring windows, icons, menus, and a pointer.

Device Drivers and Hardware Abstraction To communicate with hardware, the OS uses software called device drivers. The OS schedules tasks, ensuring that multiple applications can share the processor efficiently without conflict.
This includes the central processing unit (CPU), memory (RAM), storage drives, and input/output devices like the keyboard and mouse. This layer of abstraction means that software developers do not need to write code for every specific piece of hardware; they can rely on the OS to provide a consistent way to access resources, improving compatibility and stability.

Without this critical layer, a computer would be an inaccessible collection of hardware unable to run the familiar programs we rely on. Process and Memory Management At a technical level, the OS is responsible for process management, which involves creating, scheduling, and terminating processes.
