When referring to technical terms related to computers, the operating system is one of them. It is important to be knowledgeable about the operating system since it is actually the program which is responsible for running a computer. In order to run other programs on a computer, any computer, it must have an operating system. Without the operating system a computer would be incapable of recognizing the keyboard’s input. Without the operating system a computer wouldn’t be able to send information to the display screen. All the important tasks performed on a computer are done so through the operating system. Keeping track of directories, files and controlling the various drives, these are all tasks performed by the computer’s operating system. In larger computer systems, the operating system is even more imperative perhaps since it is responsible for security, making sure unauthorized users cannot gain access to the computer. In a large system the operating system keeps everything organized and ensures that users and or programs which are in use at the same time do not interrupt each other. Basically without an operating system a computer would be useless.
There are several specific types of operating systems, each with a particular purpose. A multi-user operating system would be beneficial in a college or university since its purpose is to allow more than two users to access programs at the same time. There are multi-user operating systems designed to accommodate hundreds and even thousands of users. There is also an operating system referred to as multiprocessing. This operating system makes it possible for a particular program to be running on more than one PC. A multi-tasking operating system works exactly as it sounds. It permits the user to run several programs at the same time. Another operating system is called multithreading and its purpose is to help different parts of a specific program to run at the same time. Finally there is an operating system known as real time. The real time operating system is designed to instantly pick up any incoming data. It is obvious that without the operating system, the computing world would certainly be in trouble.
