What Is an Operating System?
The operating system (OS) is an integrated set of software that manages the overall computer operations and resources. The OS is inaccessible to the user, but it provides services that applications programs can utilize to make hardware and software more user-friendly.
Access to data stored on disks is an essential function of the operating system. It requires the OS to be able to provide a method of organizing the contents of each file to improve speed, reliability, and storage efficiency. This type of structure, referred to as a file-system, allows files to have attributes and names. They can also be arranged into directories or folders to create an a directory tree.
The majority of computers are equipped with a range of hardware devices, including printers, keyboards, mice and other peripherals. These devices depend on the driver software of the device to communicate with the operating system. The operating system installs, configures and manages these drivers to provide the right service to the applications. It also hides the hardware information from the users, so they can use the system without knowing about the exact configuration of the hardware.
Process Management
An OS keeps all the programs running on the computer and determines the amount of time to be allocated to each one in a multitasking system. It also handles interruptions that applications cause to divert processors’ focus and ensures there sufficient memory to allow the application to complete its task without interfering with myopendatablog.com other processes.
Operating systems also perform other tasks connected to the overall performance of the computer. For example, they maintain the primary memory, which is comprised of large arrays of words or bytes with an address for each. The OS monitors how many of these bytes are utilized by different applications and is able to move, delete or arrange them to free up space.
