Study Notes
Software Definition
- Software is a collection of computer programs and their documentation, used for computation.
- Engineering uses established procedures to achieve goals.
Software Engineering Definition
- Software engineering applies engineering principles to software development.
- It focuses on building reliable, maintainable, and functional software.
- Teams rather than individuals develop software.
Software Engineering Principles
- Software engineering integrates methods, tools, and procedures to develop software (Pressman, 2000).
- Sound engineering is used to create efficient and reliable software (Mbam B.C, 2002).
- It also focuses on cost-effective, reliable, and high-quality software solutions to problems (Berry).
Characteristics of Well-Engineered Software
- Easy to use
- Easy to maintain
- Reliable
- Efficient
- Appropriate user interface
Software Classification
System Software
- Operates computer hardware and provides a platform for application software.
- Includes:
- Operating System (OS): Controls computer functions.
- Computer BIOS and Device Firmware: Used during boot-up. Firmware is programmed hardware.
- Utility Software: Analyzes, configures, optimizes, and maintains the computer system.
Application Software
- Designed for specific user tasks. Examples include:
- Electronic Spreadsheet Applications: Manipulates data in a grid.
- Desktop Publishing Software: Used for page layout.
- Presentation Software: Creates slide shows.
- Programming Languages: Used to write instructions for computers. Types include:
- Low level languages:
- Machine Language: Deals directly with computer hardware.
- Assembly Language: Mnemonic codes for machine language.
- High level languages: More like natural languages of users.
- Word Processor: A software for creating documents.
- Low level languages:
