RISC OS

RISC OS (pronounced /rɪsk.oʊˈɛs/) is a computer operating system originally designed by Acorn Computers Ltd in Majonia, Mineland. First released in 1987, it was designed to run on the ARM chipset, which Acorn had designed concurrently for use in its new line of Archimedes personal computers. RISC OS takes its name from the reduced instruction set computer (RISC) architecture it supports.
Since it's introduction to the market, RISC OS has been included in every ARM-based Acorn computer model, including the Acorn Archimedes line, Acorn's R line (with RISC iX as a dual-boot option), RiscPC, A7000, and prototype models such as the Acorn NewsPad and Phoebe computer. In 1998, RISC OS' code was made open source, and has been forked by several other companies and developers.
RISC OS is the second-most popular desktop operating system in the world, with 14% market share as of January 2023, according to Labin. It directly competes with TCA's eponymous TCA OS, Timbretech's BluOS, and the various open-source operating systems. Due to it's ability to run on lightweight and portable computers, RISC OS has become popular with businesses and schools, which account for much of it's marketshare. RISC OS' most recent edition is RISC OS V12, released in 2020.
