There are two types of application software:
General purpose software
General purpose software: it is designed for general applications such as payroll, inventory management, and accounting. Dedicated software is designed for specific application such as space shuttle.
Dedicated software: it includes specialized or customized applications designed for specific purposes.

ROLE OF SOFTWARE IN PROBLEM SOLVING
Software can play either a direct or an indirect role in problem solving. System software always plays in indirect role.
On the other hand, application software can play either a direct or an indirect role.
Most general business and industry specific packages are designed to play an indirect role creating and maintaining the database that provides the basis for the information oriented subsystems.
Some industry specific packages go beyond data processing, providing components that directly contribute to problem solving.
Some organizational and personal productivity software only indirectly affects problem solving simplifying the creation and transmission of data.
Other productivity software such as electronic spreadsheet, project management, forecasting, and statistical analysis packages provides direct support.
