 1. The Nature of Software 1. Definition Software is a collection of programs, procedures, algorithms, and documentation that perform specific tasks on a computer system. It is intangible (not physical) and created through a process of software engineering. 2. Key Characteristics Intangible : Unlike hardware, software cannot be touched or seen directly. Engineered, not manufactured : Software is designed and developed using engineering principles, but not built in a factory. Subject to wear from change, not from age : Software doesn't degrade physically but can become obsolete or buggy through usage or environmental changes. Evolves over time : Through updates, maintenance, and enhancements. Customizable : Software can be altered to suit changing user needs or technologies. Categories of Software System Software : OS, drivers (e.g., Windows, Linux). Application Software : User-focused tools (e.g., MS Word, Photoshop). Embedded Software : Runs within h...

  2. How the Process Model differ from one another? Explain types of prescriptive process. models. ‘Spiral life cycle model is not suitable for products that are vulnerable to large number of risks’. Comment on the statement. 🌟 How the Process Models Differ From One Another? A process model is like a recipe for building software. Just like you have different recipes for making a cake, you have different models (plans) for making software. Each process model: Follows different steps . Has different goals at each stage. Is suitable for different kinds of projects . 🧠 Types of Prescriptive Process Models Prescriptive Models are like strict recipes. They tell you: What to do first. What to do next. What to check before moving ahead. Here are the common types: 1. Waterfall Model (Step-by-step) One phase completes before the next starts. Like: Planning → Design → Coding → Testing → Delivery ✅ Good for: Projects with clear requirements ❌ Bad for: ...
