Computer operating systems are computer software or software that is tasked to perform control and management of hardware and basic system operations, including run 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 your computer is a first layer that is placed on computer memory, (computer memory in this case there are hard drive, not the ram memory) when the computer starts up. While other software is run after the computer running the Operating System and Operating System will perform the core public service for softwares that. 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 core duties of the public, because it can be served and performed by the Operating System. Section of code that perform core tasks and the general is called with an Operating System kernel.
Operating System serves as a liaison between the hardware layer and software layer. in addition, the computer Operating System do all the commands are also important in the computer, and ensure that different applications can run smoothly functions simultaneously without a hitch. Computer Operating System to ensure other software applications can use the memory, perform input and output to other equipment, and have access to the file system. If several applications running concurrently, then the Computer Operating System would set a proper schedule, so that as much as possible all the processes running on computers that have enough time to use the CPU and not mutually interfere with other devices.
Examples of such computer operating system is Windows, Linux, MacOS, etc.
