Definition of Computer Operating System

Understanding Operating Systems

Understanding Computer operating system is computer software or software that served to make the control and management of hardware and basic system operations, including running software applications such as data processing programs that can be used to facilitate human activity. Operating system in English is called the Operating System, or commonly abbreviated with the OS.

Operating system software on the computer is the first layer that is placed on a computer's memory, (computer memory in this case is no hard drive, no memory ram) when the computer is turned on. While other software run after run Computer Operating Systems and Operating System will conduct a common core services for the software. Common core services such as access to the disk, memory management, task scheduling, and user interface. So that each of the software no longer need to perform the duties of the common core, as it can be served and performed by the operating system. Section of code that perform tasks and common core is called the kernel an Operating System.

The operating system serves as a liaison between the layers of hardware and software layers. Additionally, the computer's operating system is important to make all the commands to the computer and make sure that different applications can simultaneously run smoothly without problems. Computer operating system to ensure other software applications can use the memory, input and output of the other equipment, and has access to the file system. If multiple applications are running at the same time, the computer operating system will set a precise timetable, as far as possible all the processes on a computer that has enough time to get the CPU usage and does not interfere with other devices.
