Nowadays most people know what an Operating System is, and more or less, most people could describe what is it. If you don’t know yet what I am talking about I’ll gladly explain it to you;
An Operating System (or OS) is the main program that runs a computer, without it, a computer would be just useless. The OS is able to receive information from different control devices, such as a keyboard or a mouse to operate any peripheral device such as a printer. This is the most simplest description of an OS.
The most popular Operating Systems are Windows and Mac OS X for computers and Android and iOS for smartphones and tablets… but, let’s focus on the OS for computers. When did they appear for the very first time? And how were they? These are two questions that led me to start a serious investigation, and now I’m gonna share with you my research.
