The operating system controls the overall resources and operation of a computer through controlling access to the central processing unit (CPU) as well as computer memory, file storage, and input and output devices. It manages tasks such as scheduling resource usage to prevent conflicts and interference among processes, managing the content and structure of files stored on non-primary media and determining which applications require hardware components like disc drives or WiFi adapters. It also permits users to connect to the system via a Graphical User Interface or Command-Line Interface.

Process Management

The operating systems handles the start, stop and resumption of programs. It decides which applications will be first executed, for how long the CPU can be used, and when to stop. It is also able to split programs into multiple threads, allowing it to run simultaneously on multiple processors. Each of these actions is controlled by an operating system program called the process control block.

File management

Operating systems monitor the structure and contents of files stored in non-primary storage. They can transfer data between storage and memory in the event of need. They can also map a virtual memory page into a physical memory page to make it easier to access data, a process called demand paging.

It also interacts directly with the hardware on the computer via drivers and other interface software. If, for instance, an application needs to make use of specific hardware, like a WiFi adaptor, then the operating system will provide the driver, and then permit it to connect to the hardware. This allows the programmer to avoid writing a piece code for every Wi-Fi adapter disk drive, or any other hardware of the same type.
