The main function of an operating system is to manage hardware and software resources. An operating system serves as an intermediary between users and the computer hardware. It maintains a stable environment for applications to run while managing computer resources such as the CPU, memory, storage devices, and input/output devices. This management includes tasks like process scheduling, memory allocation, and facilitating communication between software applications and the hardware. By efficiently managing these resources, the operating system ensures that different programs can run smoothly at the same time, as well as provides a user interface for users to interact with the system.
