Explain in detail characteristics of software
Software has several distinct characteristics that differentiate it from other engineered products:
1. Software is Developed or Engineered, Not Manufactured​
- Software is created through development processes rather than traditional manufacturing
- There are no physical materials involved in production
- Defects are design flaws, not manufacturing defects
2. Software Doesn't "Wear Out"​
- Unlike physical products, software doesn't deteriorate with time
- Software failures occur due to design errors, not physical deterioration
- The failure curve for software is different from hardware (doesn't follow the "bathtub curve")
3. Most Software is Custom-Built​
- Despite component-based development, most software is still customized
- Each application often has unique requirements and implementation
- Reusability exists but complete standardization is uncommon
4. Software is Intangible and Abstract​
- Cannot be physically touched or seen
- Measured in terms of function and performance rather than physical properties
- Understanding requires mental abstraction
5. Software is Highly Complex​
- No two parts of software are alike (unlike standardized physical components)
- Scale of complexity often exceeds human comprehension capacity
- Interactions between components can create unexpected behaviors
6. Software is Flexible and Malleable​
- Easily modifiable compared to hardware
- Often undergoes frequent changes and updates
- This flexibility can lead to maintenance problems if changes aren't managed properly
7. Software is Logical Rather Than Physical​
- Operates through logical rules and algorithms
- Behavior is determined by design rather than physical laws
- Failures are logical rather than physical in nature
