Study Notes
System Software
- A collection of programs written to service other programs
- Manages information structures, such as compilers, editors, and file management utilities
- Manages computer functions, including operating systems, drivers for hardware, networking software, and file organizers
Application Software
- Programs that solve a specific business need and facilitate business operations or manage decision making
- Examples include word processing, editors, IDE, spreadsheet, and games
Software Application Domains
- Engineering/Scientific software: supports engineering or scientific applications, such as AutoCAD and Mathlab
- Embedded software: resides within a product or system and is used to implement and control features and functions for the end user, such as controllers in microwave ovens and fuzzy logic in washing machines
- Product-line software: programs that are of the same family and can be used to customize different needs of users, such as desktop applications like Microsoft Office and OpenOffice
- Web/Mobile applications: allows users to access the system using a network
- Artificial Intelligence (AI) software: uses AI algorithms to perform complex computations, including robotics, expert systems, pattern recognition, and advanced gaming
Legacy Software
- Older software systems that remain vital to an organization
- Software systems that were developed specifically for an organization and have a long lifetime
- Often use obsolete technologies, but are still business-critical
Why Software Change?
- Software must be adapted to meet the needs of new computing environments or technology
- Software must be enhanced to implement new business requirements
- Software must be extended to make it interoperable with other more modern systems or databases
- Software must be re-architected to make it viable within a network environment
