What is an operating system (OS)?
In the simplest definition, an operating system (OS) is a set of instructions (software) that controls some hardware. These instructions are layered over the kernel accessing the hardware directly and the command line interface (CLI) or graphical user interface (GUI) for the user (normally a human being) to interact with it. These instructions are written (coded) using in different languages from low-level languages (like machine language and assembler) to high-level languages (like C++).
Operating systems have evolved from their early days and surprisingly most modern operating systems were made a good time ago like MVS in 1964, Unix in 1969, BSD in 1977, DOS in 1980, Macintosh (or Mac) in 1984, Windows in 1985 and Linux in 1991.
In the past couple of years, a different approach to operating systems and management of resources uses thin-clients (practically dumb terminals) accessing all shared resources from a server through a web browser referred to cloud computing (web platforms).
At the same time, computers (microcomputers) have shrunk from huge machines that would normally fit in a loft (like an IBM System/360 mainframe computers) to machines that fit in your pocket like any of today's mobile phones. Computer are used worldwide for various purposes from web browsing to going to outer space (NASA).
This site takes a high level look of the various operating systems used worldwide. VintageOS is merely my opinion, the result of my curiosity of computer systems and programming. As such, the sole purpose of VintageOS is to document my experiences of rebuilding old computer systems and their operating systems and to have fun while doing the latter.
You are welcome to use VintageOS as a source of information on different operating systems at your sole discretion since I offer no guarantee that the information herein is fully accurate, regardless how much I have tried ('as-is'). I do not claim to be an expert on any of the subjects covered herein. Just like most geeks, I am constantly learning about, testing and breaking new as well as vintage (old, obsolete, ancient, historical, retro) technologies. If you have any questions and/or want to correct any errors, you are welcome to email me to correct any errors that you find. If you desire, you can copy and/or steal the contents for your school reports, but do NOT publish it on other websites and/or other media and say that you wrote this information. The latter would not be nice and is actually a form of plagiarism. You can credit VintageOS and give VintageOS a link thanks in advance.
