This category is about all aspects of software (SW) which here is taken to include the following categories:

• Application software (application software: office suites, word processors, spreadsheets, etc.)
• System software (system software: operating systems, device drivers, desktop environments, etc.)
• Programming tools (programming tools: assemblers, compilers, linkers, etc.)

The first two of these are classified for running software on computers (i.e., actually using the computers), while the last one is about developing the software in the first place.
