A computer operating system manages the software and hardware resources on a computer device. It also allows for a consistent and stable way for applications to deal with hardware without knowing every detail of the hardware.
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.
Since the operating system performs an array of functions, it is a mastermind. Without it, a computer cannot function.
