The operating system is a piece software that manages all of the hardware components of the computer. It divides the time each program needs to use the CPU. It also assigns disk space and shields data from unauthorized access. It also offers an interface between the hardware and applications programs. This allows the software to connect with a wide range of hardware devices, including printers, WiFi adapters and disk drives.

In addition to the previously mentioned features in addition, an OS allows multiple software processes to run concurrently on a single processor. Multitasking is what this is known as. It also allows users to communicate with the computer using a GUI (graphical) or command-line interface. The operating system could be a single application that runs in memory, or a collection of programs and libraries on the hard drive that are loaded into memory as required.

Error detection is another important function of an operating system. The system constantly monitors all inputs and outputs to spot errors and prevent any further issues. It also is responsible for the management of network connections as well as establishing security protocols to protect against access by unauthorized persons.

The OS also stores driver information for devices in a standard format that allows for easy identification. It is also able to install and configure drivers when hardware is changed. The OS can also translate high-level programming into machine code by using loaders and compilers. It can also move data stored on a drive when it detects a bad sector.
