What is an Operating System?
The operating system is the software that manages the underlying hardware in the computer. It divides up the amount of time each program gets to utilize the CPU. It also assigns disk space and shields data from unauthorized access. It also provides an interface between the hardware and application programs. It allows the program to work with a variety of hardware devices, including printers, WiFi adapters and disk drives.
In addition to the above features in addition, an OS allows multiple software processes to run concurrently on the same processor. Multitasking is also known as. It also allows the user to communicate directly with a computer through a GUI interface (graphical) or command line interface. The operating system may be a single application that runs in memory, or a collection programs and libraries on the hard drive that are loaded into memory as required.
Other essential functions of an operating system include error detection. The system continuously monitors input and output to detect errors and prevent them from causing additional problems. It is also accountable to manage connections to networks and create security protocols in order to prevent unauthorized access.
The OS also records device drivers in a standardized file format for easy identification. It also installs and configures new drivers if hardware is replaced. The OS can also convert a high-level program into machine code using a compiler and a loader. It can even move data on a disc when it detects bad sectors.
