Operating SystemsMany people use computers without knowing how it works. The main software when using the computer is the operating system. The operating system defines the entire experience when using a computer, manages the hardware and software resources of the computer system, provides applications with a way to manage the hardware without having to know all the details of the hardware, and it is the software that creates all programs. we use work and it organizes and controls our computer hardware. Operating systems are the first software we see when we turn on the computer and the last software we see when the computer is turned off. It is important to know and understand that not all computers have operating systems. For example, the computer that controls the microwave oven in your kitchen doesn't need an operating system, it just has simple tasks to perform, very simple input and output methods (a keyboard and an LCD screen). An operating system would not be necessary for a computer like this; it will only add things that are not necessary. However, the computer in a microwave oven always runs only one program. When using computer systems more complex than a microwave oven, an operating system is required for the computer to function. All desktop computers have operating systems. The most common are the Windows family of operating systems, the UNIX family of operating systems, and the Macintosh operating systems, and hundreds of other operating systems are available for special applications. The operating system plays the role of a good parent, making sure that each application gets the necessary paper system that can be used by businesses and consumers together. Linux, the operating system created and distributed according to open source principles, could have a significant impact on the operating system in general. Most operating systems, drivers, and utilities are written by commercial organizations that distribute executable versions of their software, versions that cannot be studied or modified. Open source requires the distribution of original materials that can be studied, modified and developed, with the results once again distributed freely. The continued growth of the Internet and the proliferation of computers that are not standard desktop or portable machines means that operating systems will change to keep pace, but the core management and interface functions will continue, even as they evolve..
