'''BeOS''' is a discontinued operating system developed by [[Be Inc.]] in the early 1990s. It was designed primarily for digital media work, featuring a preemptive multitasking kernel, a modular object-oriented API, and a 64-bit journaling filesystem (BFS). BeOS initially targeted the [[PowerPC]] platform but later was ported to [[Intel x86]]. Despite strong technical merits, it failed to achieve widespread commercial success.

== History ==

Be Inc. was founded in 1990 by former Apple executive [[Jean-Louis Gassée]]. The first version of BeOS, released in 1995, ran on Apple's PowerPC-based [[Macintosh]] computers. After Apple declined to acquire Be Inc. in 1996 (instead purchasing [[NeXT]]), BeOS was ported to the [[Intel x86]] architecture. Version 4.5 and later releases, including the final commercial version 5 (dubbed [[BeOS R5]]), were available for x86. In 2001, Palm Inc. acquired Be Inc. for its intellectual property, effectively ending development of BeOS. The source code for some components was later released under open-source licenses, leading to the [[Haiku (operating system)|Haiku]] project, which aims to recreate BeOS functionality.

== Features ==

BeOS offered true preemptive multitasking with multithreading support, a symmetric multiprocessing (SMP) kernel, and a low-latency audio subsystem. Its graphical user interface, the Workspace, used a flat design with a single-pane file manager (Tracker). The BFS filesystem supported extended attributes and queries, enabling fast file indexing. BeOS also included a custom [[C++]] API (the Be API) with extensive support for multimedia, networking, and graphics. The operating system was noted for its quick boot times and efficient memory use.

== Legacy ==

Although BeOS never gained a significant market share, its design influenced later operating systems. The Haiku open-source project continues to develop a compatible implementation. BeOS is remembered for its pioneering work in desktop multimedia and as a cult favorite among enthusiasts.
