What is MS-DOS?
DOS stands for Operating System, and MS-DOS, like many computer operating systems, takes its name from the manufacturer of its processor, the MS-DOS logo or simply, just “DOS”. It was Microsoft’s first commercial operating system, and began development on January 30, 1975. After months of designing and implementing new features, the first commercial copies of MS-DOS were made available on August 20, 1975 to Tandy/Radio Shack computers. In 1975 the first portable computer with a cassette interface, the Tandy-Macintosh Portable 512K, was released to the public. It used a single-drive cassette storage device, along with a TRS-80 model 100 keyboard.
How does MS-DOS work?
Much like Windows, Linux, Android, and macOS, MS-DOS uses a hierarchical file system for storage and retrieval of data. This means that the file system consists of several levels, with each being more complex than the one below it. Here’s an MS-DOS structure chart. You’ll notice that the top level of the hierarchy is almost like a “virtual file system,” which is a pretty fancy name for the hierarchical structure, where every file and folder is a child of every other one: In this hierarchical structure, the least complex is the first directory on the top level, which contains the Files (folders) directory. The Finder in MacOS is a “direct” instance of a file in this same top level: (This is also what MacOS refers to as “..

The same MS-DOS system can run on different operating systems based on the same architecture, such as x86, PowerPC, and ARM architectures. Franchise MS-DOS, along with Windows and Microsoft Windows, are registered trademarks of Microsoft.
We all had to deal with the venerable MS-DOS on our computers for years. They were elegant yet cumbersome. People even made jokes about it, like it being a fancy vegetable called “Mushroom”. But all of that ended when people embraced the newer Windows. So let’s take a look at the history of DOS, why it has given way to Windows, and how we used to do just about everything on our computers with MS-DOS.Microsoft first started to develop MS-DOS in 1979 with the advent of the Altair 8800 microcomputer. At the time, people wanted to create and make programs for these new computers, but this new market was complex and confusing. The Altair, for example, was a low cost computer which could be powered by 4 AA batteries.
