The operating system is the program that manages the hardware in computers. It splits the amount of time each program gets to run on the CPU. It also allocates disk space and protects data from unauthorised access. It also allows interfacing between the hardware and applications programs. This allows the software to interact with a wide variety of hardware devices such as printers, Wi-Fi adapters and hard disk drives.
In addition to the aforementioned features In addition to the above features, an OS allows multiple software processes to run concurrently on one processor. This is referred to as multitasking. It also allows the user to communicate directly with a computer through a GUI interface (graphical) or command line interface. The operating system can be an individual program that runs in memory, or a set of programs and libraries that reside on the hard drive and are loaded into memory when needed.
Error detection is yet another crucial feature of an operating system. The system constantly monitors all inputs and outputs in order to identify errors and prevent further problems. It is also responsible for managing networks and the creation of security protocols to guard against unauthorized access.
The OS also records driver drivers in a standard format to allow for easy identification. It is also able to install and configure new drivers if the hardware is upgraded. In addition it can OS can translate user programs from high-level language to machine code with the help of a compiler and loader. It can even move the data stored on a hard drive if it detects the presence of a bad sector.
