Microsoft DOS: A Friendly Guide to the Original Command Line Hero
When you think of modern operating systems, names like Windows, macOS, or Linux might pop into your mind. But long before the fancy graphical interfaces, there was a simple, powerful, and text-only hero called MS-DOS.
Yes, we're talking about Microsoft Disk Operating System, the foundation that made modern Windows possible. If you're curious about old-school computing, retro tech, or just want to explore the roots of your Windows PC, buckle up—we’re going back to the 1980s!
🕰️ What is MS-DOS?
MS-DOS stands for Microsoft Disk Operating System, first introduced in 1981. It was the dominant OS for IBM PCs and compatibles until Windows started taking over in the 1990s.
Here’s the kicker: there’s no mouse, no windows, no icons—just text commands typed into a black screen. It may sound scary, but MS-DOS is surprisingly easy to use once you get the hang of it.
Think of it like texting your computer what to do… one line at a time.
