IBM Personal Computer
open-in-new
<p>The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first <a href="/facts/Microcomputer/ETW22UTv">microcomputer</a> released in the <a href="/facts/List_of_IBM_Personal_Computer_models/TMbssamV">IBM PC model line</a> and the basis for the <a href="/facts/IBM_PC_compatible/zGUpl7Sh">IBM PC compatible</a> <i>de facto</i> standard. Released on August 12, 1981, it was created by a team of engineers and designers at <a href="/facts/IBM/QszA7nwd">International Business Machines</a> (IBM), directed by <a href="/facts/William_C._Lowe/TpzsvII6">William C. Lowe</a> and <a href="/facts/Philip_Don_Estridge/d2u5L9zA">Philip Don Estridge</a> in <a href="/facts/Boca_Raton,_Florida/9gcNen3S">Boca Raton, Florida</a>. </p><p>Powered by an <a href="/facts/X86/Kypq5fgu">x86</a>-architecture <a href="/facts/Intel_8088/DdWKfyBp">Intel 8088</a> processor, the machine was based on <a href="/facts/Open_architecture/mou6VjUD">open architecture</a> and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had <a href="/facts/Influence_of_the_IBM_PC_on_the_personal_computer_market/SqQeVCD5">a substantial influence on the personal computer market</a>; the specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from <a href="/facts/Apple_Inc./oTJYta3k">Apple</a>'s <a href="/facts/Macintosh/8GhnXTK0">Macintosh</a> product line, as well as consumer-grade platforms created by companies like <a href="/facts/Commodore_International/SlfXKbCN">Commodore</a> and <a href="/facts/Atari_Corporation/xEQfvRP7">Atari</a>. Most present-day personal computers share architectural features in common with the original IBM PC, including the <a href="/facts/Intel/SMF0gJJX">Intel</a>-based <a href="/facts/Apple%E2%80%93Intel_architecture/1GpN0gWz">Mac computers manufactured from 2006 to 2022</a>. </p>
