A computer is a dumb machine that operates strictly according to instructions and cannot perform useful tasks without software.
The program-development process consists of:
Requirements → analysis → design → implementation → testing → documentation
1. Why can a computer not produce useful results without software?
2. Which sequence best represents the program-development process?
3. What does a requirements specification primarily describe?
Why is a computer called a dumb machine?
It operates strictly according to instructions and cannot perform tasks without software.
What is the first step in the program-development process?
Requirements specification.
Which step follows problem analysis in program development?
Algorithm design.
What is the final step in the program-development process?
Documentation.
What does requirements specification state about the problem?
It states the problem, required inputs and resources, expected outputs, and constraints.
What are the inputs in the apple-cost problem example?
Apple quantity in kilograms and cost per kilogram.
