A hypervisor is software that implements a virtual machine in which an operating system can run; it could be thought of as a type of operating system (it's the "true operating system" referred to by the source you're citing). ← Previous edit		Revision as of 08:24, 21 September 2024 view source Guy Harris (talk \| contribs) Extended confirmed users 79,938 edits →Microcomputers: Remove comment about macOS that is not relevant to the rest of the sentence, which is discussing Macs from long before Mac OS X/OS X/macOS as being the first personal computers with a GUI. (It'd be more relevant in the final sentence, which discusses UNXes, but it's also a bit incomplete and potentially misleading - in what way does having some* FreeBSD code make it "UNIX-based"?)

Line 100: The invention of [[large scale integration]] enabled the production of [[personal computer]]s (initially called [[microcomputer]]s) from around 1980.{{sfn\|Tanenbaum\|Bos\|2023\|pp=15–16}} For around five years, the [[CP/M]] (Control Program for Microcomputers) was the most popular operating system for microcomputers.{{sfn\|Tanenbaum\|Bos\|2023\|p=16}} Later, IBM bought the [[DOS]] (Disk Operating System) from [[Microsoft]]. After modifications requested by IBM, the resulting system was called [[MS-DOS]] (MicroSoft Disk Operating System) and was widely used on IBM microcomputers. Later versions increased their sophistication, in part by borrowing features from UNIX.{{sfn\|Tanenbaum\|Bos\|2023\|p=16}} [[Steve Jobs]]' [[Macintosh]]~~, which after 1999 used the UNIX-based (via [[FreeBSD]]){{sfn\|Tanenbaum\|Bos\|2023\|pp=17–18}} [[macOS]],~~ was the first popular computer to use a [[graphical user interface]] (GUI). The GUI proved much more [[user friendly]] than the text-only [[command-line interface]] earlier operating systems had used. Following the success of Macintosh, MS-DOS was updated with a GUI overlay called [[Windows]]. Windows later was rewritten as a stand-alone operating system, borrowing so many features from another ([[VAX VMS]]) that a large [[legal settlement]] was paid.{{sfn\|Tanenbaum\|Bos\|2023\|p=17}} In the twenty-first century, Windows continues to be popular on personal computers but has less [[market share]] of servers. UNIX operating systems, especially Linux, are the most popular on [[enterprise system]]s and servers but are also used on mobile devices and many other computer systems.{{sfn\|Tanenbaum\|Bos\|2023\|p=18}} On mobile devices, [[Symbian OS]] was dominant at first, being usurped by [[BlackBerry OS]] (introduced 2002) and [[iOS]] for [[iPhone]]s (from 2007). Later on, the open-source, UNIX-based [[Android (operating system)\|Android]] (introduced 2008) became most popular.{{sfn\|Tanenbaum\|Bos\|2023\|pp=19–20}}
