What is the primary function of an operating system?

The primary function of an operating system is to manage hardware and software resources. This involves overseeing the computer's hardware components such as the CPU, memory, disk drives, and peripherals, as well as facilitating the execution of software applications. The operating system acts as an intermediary between users and the computer hardware, ensuring that all parts of the system work together effectively and efficiently.

By managing these resources, the operating system allocates memory, prioritizes processes, and handles input and output operations, which ensures that applications run smoothly without conflicts or resource contention. This capability is essential for the stability and performance of the entire computing system, allowing users to interact with the software without needing to understand the complexities of the hardware.

In contrast to other functions, like serving web pages, compiling source code, or merely connecting devices to a network, the operating system's resource management is foundational, as it provides the necessary environment for all other functions to operate successfully within a computing system.
