Study Notes
Application Software
- Application software is designed to solve specific problems and enables users to perform productive tasks.
- It uses a computer as a tool and cannot be directly understood by the underlying hardware.
Types of Application Software
- Utility software: designed for maintenance and monitoring activities (e.g., anti-virus software, firewalls, disk utilities).
- System software: provides infrastructure for programs to operate, controls computer hardware and resources, and allows interaction with computers.
System Software
- Includes operating systems, device drivers, language translators, assemblers, linkers, loaders, macro processors, text editors, compilers, debugging systems, and source code control systems.
- System software is responsible for controlling computer hardware and providing services to application software.
System Programming
- Aims to produce system software that provides services to computer hardware or specialized system services.
- Characteristics:
- Programmers need to know hardware and internal behavior of the computer system.
- Uses low-level programming languages or dialects.
- Requires little runtime overhead and can execute in resource-constrained environments.
- Has access to system resources, including memory.
- Can be written in assembly language.
- Limitations:
- Cannot be run in debugging mode.
- Limited programming facilities require high skills.
- Less powerful runtime library (if available).
Software Characteristics
- Include performance, portability, and functionality.
- Quality factors:
- Operational characteristics: correctness, usability, integrity, reliability, efficiency, security, and safety.
- Transitional characteristics: interoperability, reusability, and portability.
- Revision characteristics: maintainability, flexibility, extensibility, scalability, testability, and modularity.
Software Hierarchy
- Computer software includes computer programs, system libraries, and associated documentation.
- Classified into application software, utility software, and system software.
