Operating System software

Usually, the term often Operating System software is addressed to all who enter in one package with the computer system before the software applications installed. In computer science, operating system or in English: the operating system or OS is a software system that served to make the control and management of hardware and basic system operations, including the software applications like word processing programs and web browsers.

In general, the Operating System software on the first layer is placed on computer memory when the computer starts up. While other software is run after the Operating System is running, and operating systems will perform the core public service to the software. Core public services such as access to the disk, memory management, task scheduling, and user interface. So that each software does not need to perform tasks common core, as can be managed and conducted by the Operating System. The code of tasks and common core is called the "kernel" of a Operating System

If the computer system divided into layers, then the Operating System is the liaison between the layers of hardware and software layers. More than the Operating System to perform all tasks necessary in the computer, and ensure that different applications can run simultaneously with the current. Operating System ensure other software applications can use the memory, perform input and output of other equipment, and have access to the file system. When running several applications simultaneously, then the Operating System skedule the right, so far as possible all running processes get enough time to use the processor (CPU) and do not interfere with each other.
