MS-DOS (1981-1999)
MS-DOS was the Microsoft Disk Operating System, a 16-Bit command line operated enviroment for early 16 bit x86 personal computers. Initaly licenced for the IBM PC 5150 in 1981, Microsoft DOS quickly become the worlds standard for IBM computers and the flurry of IBM compatibles that shapped personal computing from then onwards outside of the buisness of the toy-like microcomputers.
Windows DOS (1985-2000)
DOS-Based Windows initaly debuted in 1985 as a crude graphical shell to Microsoft's own DOS enviroment. these systems required DOS as it was nothing more than a graphical overlay, and it wasn't until the release of Windows 95 that a 32-Bit DOS based release transitioned the DOS-based GUIs away from needing MS-DOS preinstalled, despite still using the technology.
 OS/2 (1987-2001)

In 1987, Microsoft and IBM cooperated on a joint development agreement to develop and produce a worthy successor to the aging DOS operating system, resulting in a fully 32-Bit revolutionary operating system architecture that was squandered by the ongoing microsoft monopoly, confusing and lackluster marketing, and high-system requirements that kept it out of reach of general consumers.

With the release of Windows 95, IBM's efforts to sustain OS/2 were hemeraged, and the platform quielty faded into obscurity until its final update in 2001, subsequently put under licencing requests to sell off to technilogical neiches or nessasary embedded systems.

Windows NT (1993-2021)

While DOS-based Windows needed little processing power and memory to run, it inherited the limitations and vunerabilities of the 16-Bit DOS architecture. To fix this, they reorganized their code from the divorced projoect of IBM's 32-Bit operating system 'OS/2' under the windows graphical shell, initaly releasing in 1993. This new totaly 32-Bit architecture was far more capable and secure in compraison to DOS releases of Windows, but required much more system resources, only becoming consumer-viable with the release of Windows XP in 2001.

 

 

Macintosh System (1984-1997)

Apple's lone warrior 'Macintosh' was designed around the idea of making computing more userfriendly, human-oriented, and of course, easier. taking cues from the failed apple lisa and the revolutionarly snuffed Xerox Altar, Apple provided its users with a desk-like operating system including a dynamic options dashboard, overlapping windows, and seemless bessels on all that intimidating and nerdy computer gargin.

While visualy and praticaly innovative, multitasking was praticaly non-existent, with the system relying on running a single program at a time when selected, still working off the vunerablility that if one program crashed the system would loose its ball and crash.

Classic MacOS (1997-2001)

The classic MacOS was essentialy built on the NeXTStep UNIX architecture bought by Apple from the now defunct NeXT Computers company. This system rewrite acted as a formidable stopgap between the long-obselete Macintosh System software and the upcoming final end goal of MacOS X.

the classic MacOS retained the layouts and general natures of the previous macintosh system releases, but internaly replaced and isolated the old kernel with the NeXT kernel, allowing for simotanious multitasking, greater processing efficency, and greater internet and networking capabilities in time for the increasingly internet-oriented world.

MacOS X (2001-2024)
MacOS X debuted in 2001 and finnaly bridged the gap after the decline of Macintosh System software and the stopgap measures of MacOS 8 and 9. This new line of releases rebranded the whole Macintosh enviroment, introducign a flashy new visual style, a dock of convenient programs and shortcuts, addedd software and hardware capabilities, and many other generals tweaks that made operating much easier.
