Extensible Operating Systems Software
Extensible Operating Systems Software
Any operating system (OS) can be extended before runtime, by two means: 1) Programming; if one has the source code, by programming (coding) and then compiling the new code into a new system, and/or, 2) Patches; by applying patches into a system.
On this page, OSs are arranged in three groups and levels: 1) Top group: types or classes of OSs. 2) Middle group: OSs for which there are more than one instance of an OS of this name/type, an OS family. 3) Bottom group: specific OSs, individual instances; there is only one OS of this name/type.
