Software Basics Module 1

Study Notes

Software consists of instructions (programs) for performing tasks and managing resources, data structures for information manipulation, and documentation for operation guidance.

Application Software: Allows users to perform specific tasks.
- Customized Software: Tailored to meet individual customer requirements.
- Packaged Software: Pre-developed for general sale to the public.
  - Word Processing: Create, edit, save, and print documents.
  - Spreadsheets: Analyze data using rows, columns, and formulas.
  - Database Manager: Manages multiple data files.
  - Graphics Software: Create presentations through charts, graphs, and artwork.
  - Communications Software: Facilitates data transmission over networks.
System Software: Engages with application software and manages computer resources.
- Operating System: Oversees basic computer operations.
- Utility Programs: Offer additional services not covered by other software.
- Language Translators: Convert programming languages into machine-readable formats.

Developed by software engineers, differing from traditional manufacturing.
Software doesn't physically wear out but can deteriorate over time.
Despite the trend toward component-based designs, custom-built software remains prevalent.
Functions simultaneously as both a product and a means to develop other products.

System Software: Serves other programs (e.g., compilers, file management utilities).
Application Software: Addresses specific business needs, streamlining operations and decision-making.
Engineering/Scientific Software: Focuses on intensive numerical calculations.
Embedded Software: Integrated within products to manage features for users and systems.
Product-Line Software: Provides capabilities for diverse customer bases.
Web Applications (WebApps): Network-centric software that offers various functionalities.
Artificial Intelligence Software: Employs non-numerical algorithms for complex problem-solving.
Open-World Computing: Characterized by pervasive wireless networking.
Netsourcing: The internet as a computing engine and content provider, driving innovation in software.
Open Source: Encourages community contributions to software development, especially in operating systems and databases.

Adaptation needed for changing computing environments and technologies.
Enhancement required for evolving business needs and interoperability with modern systems.
Software re-architecture necessary to fit within networked environments.

Software is integral to modern life, increasing interest in specific applications.
Software engineering applies sound engineering principles for creating economically efficient software solutions.
