Layia septentrionalis is an uncommon species of flowering plant in the daisy family known by the common name Colusa tidytips, or Colusa layia.

<programming> (Or "computer program", "program", "code") The instructions executed by a computer, as opposed to the physical device on which they run (the "hardware"). The term was coined by the eminent statistician, John Tukey. Programs stored on non-volatile storage built from integrated circuits (e.g. ROM or PROM) are usually called firmware. Software can be split into two main types - system software and application software or application programs. System software is any software required to support the production or execution of application programs but which is not specific to any particular application. Examples of system software would include the operating system, compilers, editors and sorting programs. Examples of application programs would include an accounts package or a CAD program. Other broad classes of application software include real-time software, {business software}, scientific and engineering software, {embedded software}, personal computer software and {artificial intelligence} software. Software includes both source code written by humans and executable machine code produced by assemblers or compilers. It does not usually include the data processed by programs unless this is in a format such as multimedia which depends on the use of computers for its presentation. This distinction becomes unclear in cases such as {spread sheets} which can contain both instructions (formulae and macros) and data. There are also various intermediate compiled or semi-compiled, forms of software such as library files and byte-code. Some claim that documentation (both paper and electronic) is also software. Others go further and define software to be programs plus documentation though this does not correspond with common usage. The noun "program" describes a single, complete and more-or-less self-contained list of instructions, often stored in a single file, whereas "code" and "software" are uncountable nouns describing some number of instructions which may constitute one or more programs or part thereof. Most programs, however, rely heavily on various kinds of {operating system} software for their execution. The nounds "code" and "software" both refer to the same thing but "code" tends to suggest an interest in the implementation details whereas "software" is more of a user's term. (2002-07-21)

We should try to genericise this bit of the software.

Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work.

Customised software (also known as bespoke software or tailor-made software) is software that is specially developed for some specific organization or other user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf software, or existing free software.

<programming> A type of COM component that can self-register, also known as an "ActiveX control". All COM objects implement the "IUnknown" interface but an ActiveX control usually also implements some of the standard interfaces for embedding, user interface, methods, properties, events, and persistence. ActiveX controls were originally called "OLE Controls", and were required to provide all of these interfaces but that requirement was dropped, and the name changed, to make ActiveX controls lean enough to be downloaded as part of a web page. Because ActiveX components can support the OLE embedding interfaces, they can be included in web pages. Because they are COM objects, they can be used from languages such as Visual Basic, Visual C++, Java, VBScript.

Software categories are groups of software. They allow software to be understood in terms of those categories, instead of the particularities of each package.
