Software Engineering

Q1. Can you explain what a program is?

Answer - A program is a set of instructions that perform a specific task.

Q2. What is software, and what does it involve?

Answer - Software is a program with proper documentation, including a user manual, maintenance guide, installation guide, licensing, and other official procedures.it is a commercial product.

Q3. Why is software engineering necessary?

Answer - While hardware development has improved significantly over time, software development has not kept up. Many software projects fail or go unused, resulting in a waste of time and money. To avoid this, a proper approach and ideology are needed to reduce the failure rate of software. Software engineering is an approach to software development that involves designing, implementing, testing, and maintaining software while also conducting advanced budget and work analysis.

Q4. Explain the characteristics of Software Engineering.

answer - 

1. Correctness - the software should perform a task that was demanded, there might be better and more efficient tasks but the developer should stick with the requirement.
2. Reliability - it should give accurate and the same results over the same output.
3. Maintainable -  maintenance of the software should be possible 
4. Usability - The user should use and understand the software with ease. the software should be comfortable in use.
5. Efficiency - the software should work with optimal resources 
6. Portability - The software should work in various environments and machines with minimal changes
7. Scalability - the software should be able to handle the sudden increase in usage.
8. Security - the data of the users should be safe and not interrupted by third parties.
9. Modularity - The program is broken into small pieces so that various functions can be performed individually without the effect of others.
10. Testable- The software should be able to go through various testing protocols
11. Reusable - The software should be reused for similar operations with no significant changes
