What Is an Operating System?

The operating system (OS) is an integrated set www.myopendatablog.com/virtual-board-room-for-tech-and-business-leaders/ of specialized programs that manage overall computer operations and resources. From the perspective of a user’s viewpoint, the OS is inaccessible — however, it offers applications with services they can use to make hardware and software more useful.

This is an essential operation system feature. The OS must be capable of organizing the contents of files in order to increase speed, reliability and storage efficiency. This structure, called the file-system, allows files to have attributes and names. They can also be arranged into folders or directories to create an a directory tree.

The majority of computers come with a variety of hardware devices, like keyboards, printers, mice, as well as other peripherals. These devices depend on driver software for the device to communicate with the operating system. The operating system installs, configures and manages these drivers in order to offer the correct service to applications. It also hides details about the hardware to users so that they can interact with their system without having to know the exact configuration of their hardware.

Process Management

OSs track the running applications on a computer. They also determine the amount of time each application should receive in a multitasking environment. It also controls the interruptions that programs create to keep a processor’s focus and ensures there is enough memory to allow an application to finish its work without interfering other processes.

Operating systems perform other functions related to the overall performance of the computer. For instance they maintain the primary memory that contains large word or bytes arrays with an address for each. The OS can track how many bytes are used by different applications and move, delete, or reorganize these bytes to free up space.
