Study Notes
What is Software
- Software is more than just a program. It includes instructions, data structures and documentation that allow the program to function properly.
- Instructions are computer programs that execute to produce the desired behavior.
- Data Structures are collections of data used by the programs to manipulate information. Examples of this include "Fee", "DoB", "Price", "Amount".
- Documentation describes how the program operates and how it should be used.
Software Classification
- There are two main categories of software based on usage:
- System Software directly controls the hardware resources (e.g., memory, CPU, disk storage) and supports the operation of Application Software.
- Application Software serves user requirements in a particular application domain (e.g., business) and is used to carry out specific tasks.
- Software can also be classified based on development:
- Generic Products are off-the-shelf products that are widely sold. Examples include payroll systems, point of sale systems, and stock control systems.
- Bespoke Products are custom-built products that are designed for a specific customer. Example: A student management system written for ESOFT, a specific college.
System Software
- System software examples include:
- Operating Systems, such as Windows 7, Vista
- Program Translators, which include Interpreters and Compilers
- Utility Software, examples include Virus Scanners, Disk Defragmenters, and Disk Cleanup tools.
Application Software
- Application Software categories:
- Business Software: examples include accounting software, payroll programs, stock control systems, and productivity suites like MS Office.
- Scientific & Engineering Software: examples include CAD (Computer Aided Designing) and CAM (Computer Aided Manufacturing) software
- Real Time Software is used in situations where immediate responses are critical, such as in fire detection systems.
- Embedded Software is often embedded in devices like motor vehicles.
- Personnel Computer Software: Examples include Office Packages and Excel.
- Artificial Intelligence Software: examples include robotic systems.
Generic vs Bespoke Products
- Generic Products are off-the-shelf software that can be purchased and used by any customer. They are ready-made and can be implemented quickly.
- Bespoke Products are tailor-made software, built specifically for a customer's needs. These products require development time and can be costly since the development cost is borne by one customer.
Software Quality Features
- Maintainability: Software should be easy to modify and upgrade to meet changing customer needs. Well-documented software with clear comments is easier to maintain.
- Dependability encompasses a range of characteristics like reliability, safety, and security. Dependable software should not cause physical or economic harm if it fails.
