What is an operating system (OS)?
In the simplest definition, an operating system (OS) is a set of instructions (software) that controls a machine (hardware) providing an interface for the user. 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 coded using in different languages from low-level (like machine language and assembler) to high-level (like C and 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 (now referred to as macOS) 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 (commonly referred to as 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 fit in a loft (like an IBM System/360 mainframe) to machines that fit in your pocket like any of today's mobile phones. Computers are used worldwide for various purposes from web browsing to going to outer space (NASA).
This site takes a high level look at various operating systems used worldwide. It 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.
If you are interested in experimenting with any operating system covered in VintageOS, you can create a VDI with VirtualBox (free) or similar application.
On 11/17/2014, VintageOS received the Web Literacy Skill Sharer badge from Webmaker, part of the Mozilla Foundation.
"Web Literacy Skill Sharer
Issued by: Webmaker
This badge can be issued to people who have shared a web literacy skill and written about their experience on the web. Here's how to earn this badge:
1) Explore the competencies listed in the Web Literacy Map
2) Choose one of the 15 competencies that you feel especially passionate about
3) Look at the list of skills underpinning that competency, and then share one of those with someone else — either using one of the suggested resources or by inventing your own way of teaching it
4) Share a blog post, video or image online illustrating how you taught the web literacy skill"
