One Small Memoir

There is the operating system. The interface between a person and a system is known as the operating system. There are different operating systems like Windows, solarix, and Unix. Thus Dos is known as a disk operating system my dear friends. This is a command-based operating system, my dear friends. Also, MS-DOS comes from Microsoft, my dear friends. Also, there is a run prompt when we open windows Windows is not command-based, windows have a nice English language interface. Thank you dear all for motivating me to read and write.
