Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components with other computers easy. [1] For example, the IBM PC, [2] Amiga 2000 [3] and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc computer has a closed architecture.
A Hackintosh (/ ˈ h æ k ɪ n t ɒ ʃ /, a portmanteau of "Hack" and "Macintosh") is a computer that runs Apple's operating system macOS on computer hardware that is not authorized for the purpose by Apple. [1] This is due to the software license for macOS only permitting its use on in-house hardware built by Apple itself, in this case the Mac ...
The storage of computer programs is key to the operation of modern computers and is the connection between computer hardware and software. [7] Even prior to this, in the mid-19th century mathematician George Boole invented Boolean algebra —a system of logic where each proposition is either true or false.
By 1977 pre-assembled systems such as the Apple II, Commodore PET, and TRS-80 (later dubbed the "1977 Trinity" by Byte Magazine) [44] began the era of mass-market home computers; much less effort was required to obtain an operating computer, and applications such as games, word processing, and spreadsheets began to proliferate.
On August 12, 1981, IBM released the IBM Personal Computer. [10] One of the most far-reaching decisions made for IBM PC was to use an open architecture, [11] leading to a large market for third party add-in boards and applications; but finally also to many competitors all creating "IBM-compatible" machines.
The market for personal computers was dominated at the time by Tandy, Commodore, and Apple, whose machines sold for several hundred dollars each and had become very popular. The microcomputer market was large enough for IBM's attention, with $15 billion in sales by 1979 and projected annual growth of more than 40% during the early 1980s.
