Home›Systems›Status›Active / In UseBrowse ByActive / In UseThis dimension marks whether a computing system is still actively developed, discontinued or superseded. Wikipedia notes that "as of November 2025, Android is the most popular operating system, with a 38% market share," a ranking that shifts as some systems keep growing while others fall out of active use. Browsing by status separates systems still current from those no longer maintained.Active / In UseConnectionsComments (0)Reader Challenges (0)Active / In UseFilter Results101 entriesSystem ClassAllClassic Mac OS and Apple Systems (1)Cloud Computing Platforms (4)Column-Oriented Database Management System (3)Distributed Data Processing Infrastructure (4)Document-Oriented Database Management System (4)DOS-Family Systems (6)Early Apple Personal Computers (1)Embedded and Real-Time Operating Systems (10)Graph Database Management System (3)Home Computer Operating Systems (2)IBM Mainframe and Midrange Systems (1)Internet Application Protocols (6)Japanese Petascale Supercomputers (1)Key-Value Database System (4)Local and Wireless Network Standards (3)Mainframe and Historical Systems (1)Mobile and Handheld Operating Systems (6)NewSQL and In-Memory Databases (1)NoSQL Database Management System (3)Relational Database Management System (15)Research and Academic Operating Systems (7)Search Engine Database (2)Time Series Database System (2)Unix and Unix-Like Systems (9)YearAll1969 (2)1973 (1)1977 (1)1979 (1)1981 (2)1982 (1)1983 (2)1984 (3)1985 (2)1986 (1)1987 (4)1988 (2)1989 (2)1990 (1)1991 (3)1992 (2)1993 (3)1995 (2)1996 (2)1997 (1)1998 (2)2000 (2)2001 (2)2002 (1)2003 (2)2004 (2)2005 (3)2006 (3)2007 (4)2008 (4)2009 (4)2010 (5)2011 (4)2012 (3)2013 (2)2014 (1)2015 (2)2016 (3)2017 (4)2018 (1)2019 (1)2020 (1)2023 (3)ACM AreaAllCloud Computing (4)Computer Architecture (3)Computer Networking (10)Databases (35)Distributed Computing (5)Embedded Systems (1)Information Retrieval (1)Internet of Things (2)Operating Systems (38)GroupAllClassic Mac OS and Apple Systems (1)Cloud Computing Platforms (4)Column-Oriented Database Management System (3)Distributed Data Processing Infrastructure (4)Document-Oriented Database Management System (4)DOS-Family Systems (6)Early Apple Personal Computers (1)Embedded and Real-Time Operating Systems (10)Graph Database Management System (3)Home Computer Operating Systems (2)IBM Mainframe and Midrange Systems (1)Internet Application Protocols (6)Japanese Petascale Supercomputers (1)Key-Value Database System (4)Local and Wireless Network Standards (3)Mainframe and Historical Systems (1)Mobile and Handheld Operating Systems (6)NewSQL and In-Memory Databases (1)NoSQL Database Management System (3)Relational Database Management System (15)Research and Academic Operating Systems (7)Search Engine Database (2)Time Series Database System (2)Unix and Unix-Like Systems (9)Invented ByAllAndrew S.
