If you've ever wondered about DOS, then this article will help you understand what it is.
Operating systems are the key to any computer. Without these operating systems, computers are just machines that take up electricity. In order to do anything with computers, an operating system is needed as a conjunction for hardware, software, and human interaction.
One such operating system used to be DOS, commonly known as MS-DOS. It was all the buzz back in the 80s and early 90s when UI wasn't a thing. But, more than 40 years later, DOS is rarely heard of. So, what exactly was or is it? And, how was it different from the operating systems we use today? Let's find out.
DOS or MS-DOS is the shortened name for Microsoft Disk Operating System. Usually seen as words on a black screen, MS-DOS looked a lot like your common command prompt on the computer today. As you can guess, the operating system requires written commands to operate.
However, DOS wasn't always "MS-DOS," as it started out in the IBM computers of the early days. Later, the rebranded Microsoft version became the primary DOS we know today. However, earlier on, it was licensed as PC DOS 1.0, owned and patented by Microsoft.
Later on, it went to Microsoft and became the primary operating system offered by the software giant after 1988—particularly after the release of the x86 framework. However, all MS-DOS production stopped in 2000, marketing the end of a remarkable 29-year run.
However, this was the very operating system that catapulted Microsoft into becoming the software-development giant we know today. But, before the introduction of GUI, DOS went through many upgrades, such as:
But by Windows 2000, Microsoft had ceased working on all the upgrades as command-based operating systems were running out of fuel. Besides that, Microsoft's own GUI operating system (Windows) had seen immense success. This marked the end of DOS' continued reign and development of over 30-32 years.
The basics of DOS are as simple as it was to use it. Granted, modern OS users may not have a clue about it, but it requires only a specific and exclusive set of things to work correctly. But how exactly did it work?
It used ROM (Read-Only Memory) to read the MBR (Master Boot Record). Then it passed the control through bootstrap leader to MBR>. However, the boot record laded the DOS into memory, allowing it to control it entirely. Then, an array of operations happen, such as:
These are some of the main ways DOS works. However, it works through two main features: CLI (command-line interface) and management. The former handles keyboard input, as DOS didn't have GUI to take mouse input. Whereas the latter handles managing files, OS, system memory, etc.
The question of advantages or disadvantages is asked of something relevant and used frequently. DOS is an outdated technology employed only in a few cases today. So, it does make it relevant to various disadvantages and advantages, which are as follows:
Advantages:
Disadvantages:
While you can still find DOS in computers in some capacity, it's still outdated a little bit. And, there are seldom any uses for it besides troubleshooting, formatting, etc.
If you got any more questions, then here are some frequently asked ones:
The DOS was used for transferring data to the disk using typed-in command lines in a computer. It allowed the user to operate various devices connected to the computer, such as printers, video screens, and other external devices.
While DOS is severely outdated, it's still used in some capacity. In every Windows-based computer, there's a PowerShell or command prompt today. It allows them to use the same commands as DOS to work around troubles or solve issues with hardware.
While they do share the same attributes, they are a bit different. As opposed to MS-DOS, a command prompt is GUI-based, so it accepts mouse input.
