The type of software that enables you to communicate with the computer and acts as a coordinator between the hardware and all running systems is called an Operating System (OS). An operating system serves as an intermediary between the user and the computer hardware, managing hardware resources such as the CPU, memory, and input/output devices, while also providing a platform for running application software. It controls the execution of programs, manages memory, handles file systems, and coordinates hardware access to ensure efficient and secure operation of the computer
. Key functions of an operating system include:
- Process management: scheduling and managing running programs.
- Memory management: allocating and optimizing memory use.
- File system management: organizing and securing files.
- Device management: controlling input/output devices.
- Providing a user interface, either graphical (GUI) or command-line (CLI).
- Ensuring security and system stability.
Examples of popular operating systems are Microsoft Windows, macOS, Linux, Android, and iOS
. In summary, the operating system is the essential software that acts as a bridge between the user, applications, and the computer hardware, coordinating all system activities.
