What are the functions of the computer operating system

A computer operating system performs countless functions. However, its primary goal is to provide an interface between the hardware and user. Additionally, an operating system acts as a resource manager. It manages all resources, such as disk space, memory and processors, attached to a system. An operating system handles storage management by controlling the storage operations of a computer. The system manages how files or data are stored in a computer.
File management is another function of an operating system. It is responsible for the organizing and tracking of directories and files that are saved or retrieved from a disk. This function also enables a user to perform various tasks, such as creating directories and files, copying and moving files, renaming files and deleting files. This system keeps track of the exact location of files on a hard drive through a specific type of file system. The two types of file systems are the New Technology File System or File Allocation table.
System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk formatters, file managers, display managers, text editors, user authentication (login) and management tools, and networking and device control software.
