'''Software''' is [[computer]] code that is converted ("compiled") into a machine-readable program capable of performing complex operations.  Software is differentiated from [[hardware]], which is a physical computer attribute, such as a monitor or [[hard drive]].  There are many different types of software, ranging from something as central to the computer as its [[operating system]] such as [[Windows]] or [[Tails (operating system)|Tails OS]], to such productivity-based software like [[Microsoft Office]], to purely entertainment software like [[video games]].

==Prescient Quotes on Police State Software Surveillance==

==Functional types==

* "The progress of [[science]] in furnishing the [[big government|government]] with means of [[espionage]] is not likely to stop with [[wiretap]]ping. Ways may some day be developed by which the [[Police state|government]], without removing papers from [[hard disk|secret drawers]], can reproduce them in [[Foreign Intelligence Surveillance Court|court]], and by which it will be enabled to expose to a [[jury]] the most intimate occurrences of the home. Advances in the [[computer science|psychic and related sciences]] may bring means of exploring unexpressed beliefs, thoughts and emotions. 'That places the [[liberty]] of every [[citizen|man]] in the hands of every [[tyrant|petty officer]]' was said by James Otis of much lesser [[tyranny|intrusions]] than these. 1 To Lord Camden a far slighter intrusion seemed '[[subversive]] of all the comforts of society.' Can it be that the [[Constitution]] affords no [[Right to Privacy|protection]] against such invasions of [[Fourth Amendment|individual security]]?"

*'''System software''' - Software which runs the various necessary functions of a computer system. The [[Operating system|operating system]] is a collection of vital system software<ref name="classification-of-software">https://prezi.com/dbxyq-gz1dle/classification-of-software</ref>

** [[Louis Brandeis]]''' (1856-1941), [[United States Supreme Court]] [[Associate Justice]] Dissenting, ''[[Olmstead v. United States]]'', 277 U.S. 438 (1928).

*'''Applications''' - Programs which run within a preexisting software environment which perform a wide variety of tasks. These programs can be generic such as a word processor, or specialized bespoke solutions like an air traffic control system.<ref name="classification-of-software"/><ref name="ecomputernotes.com">http://ecomputernotes.com/software-engineering/characteristics-and-classification-of-software</ref>

**'''Programming tools, frameworks, etc.''' - One type of application is a program which creates or supports other programs.  Code compilers, script frameworks, and other such software generate or facilitate applications, but are themselves applications.<ref name="classification-of-software"/>

*'''Autonomous software''' - As opposed to most applications, which are designed to interact with people (users), autonomous software runs without user oversight.  Such software has different names depending upon how it is used.

**'''Bots''' - programs which navigate the [[Internet|internet]], looking for specific information. For instance, search bots are used to index what is on the world wide web for [[Search engine]]s such as [[Google]] search and [[Bing]].

**'''Services''' or '''Daemons''' - programs that perform specific operations for [[Operating system|operating system]]s, such as scheduling the running of other tasks or sharing printers (aka print queues). However not all services are part of operating systems.
