When I say computer operating system, the first that comes to mind will be Windows, the most used operating system on the planet. Nowadays, everybody has a personal computer that, thanks to the user-friendly operating systems out there, they can easily use without any special training or experience. However, things have not been so simple in the past; let us look at the operating systems from the beginning until now.
Computers without operating systems are impossible to picture, but that is really how it was. The role of an operating system is to make the machine work; it binds the hardware to the programs. In the past, to make the machine run, each program had to have the codes necessary; as computers became more sophisticated, so did the various operations. As an operating system and an application, it became inconvenient for any program to run; a need for an operating system emerged.
In 1956, the first operating system to operate an IBM mainframe computer was developed by IBM, a well-known computer company; other mainframe owners did the same and created their own operating systems. For all computers, there was not a single operating system; programs also had to be updated to run on various operating systems.
Microsoft is known for Windows today, but Windows wasn't their first operating system. Their first was known as Microsoft Disk Operating System, short for MS-DOS. MS-DOS varies from the operating systems you know; people who have used MS-DOS will use command lines to access or open their files. To make the machine work, it was like writing a condensed code; for example, if you need to run a notepad, you'll have to write "notepad." It's entirely different from the graphical user interface we're using today; you can see what you want now and just click on it, but you've had to memorize the commands in the past.
More or less, our environment has been revolutionized by Microsoft Windows; we don't have to know commands by heart. We owe Alan Kay, Douglas Engelbart, and others who created it in 1981 to the Graphic User Interface, also known as GUI; based on it are Microsoft Windows and various user-friendly interfaces. From using a mouse to click on the icon you need, user-friendly interfaces have advanced to touch screens that allow you to click on what you need directly.
What is the future going to hold for us? The question had already been raised by Forbes magazine and the response they came up with was: Blockchain Operating System. Blockchains are data-storing blocks; they are used for financial transactions, for example. It can not be altered once data is stored; if you pay for an item online, the block is saved, and you won't have to pay twice.
A blockchain operating system is a virtual operating system that connects the cloud to your laptop, computer, or cellphone, making it convenient, immutable, and protected to move data since it is not controlled by any individual. In plain English, the inconvenience of getting multiple devices and isolated data is removed by a blockchain operating system. It somehow ties everything together; from signing your contracts online, it will make life easier, to maybe linking your kitchen to the store so that you never run out of any products. Well, we're not going to wait long; the future's almost here!
