This is the language of commerce and is constantly being degraded, e.g.
At different times the same computer application may be called application software, or enterprise software, or legacy software.
Definitions, like software, are fluid
In addition to the above issue, technological progress changes categories. An enterprise software package may include a financial management capability. A year later, the financial management capability will not be part of the software package because it is handled by Excel instead.
What software is categorized as has financial and legal consequences
- Microsoft includes a calculator application as part of Windows. Is a calculator part of the operating system?
- Microsoft does not include an anti-virus program as part of Windows, although you can download an anti-virus program from Microsoft’s website.
- Would anti-virus software companies sue Microsoft for an anti-trust violation if Microsoft included an anti-virus program?
Computer Software Industry Segments
The computer business is divided into several large, for want of a better word, segments. Keep the example of the calculator application in mind and recognize that applications can move from segment to segment and that these definitions are more fluid then most academic definitions.
