An operating system is kind of like the brain of a computer. You have a bunch of hardware like the CPU tower, the monitor, and the keyboard, but without a CPU, they cant do anything but power up and turn on. The operating system organizes files and lets the hardware know what it should do.

In the early days of computers, there was just one operating system. As computers progressed, the OS turned into MS-DOS, but computers really werent capable of doing much without software.

The operating system is the most important program that runs on a computer. Without an operating system, your computer would not work. It would not be able to process requests for print, simple calculations, or any other function. It is really the brain that runs the equipment.
