What is the primary function of an operating system?

The primary function of an operating system is to manage computer resources and provide a user interface. This includes coordinating between the hardware and software of a computer, allowing for effective utilization of its components, such as the CPU, memory, and storage devices. The operating system acts as an intermediary, ensuring that different applications can operate efficiently without interfering with one another or the hardware.

Additionally, the operating system offers a user interface that enables users to interact with the computer easily. This can include graphical user interfaces (GUIs) that utilize windows, icons, and menus, as well as command-line interfaces. By providing these access points, the operating system makes it easier for users to launch applications, manage files, and customize settings to suit their needs.

While protecting against malware and developing applications are important tasks associated with computing, they are not the primary functions of an operating system. The OS's main role is focused on resource management and user interaction.
