2. What are the two fundamental types of software product?
Generic products that are designed to meet the needs of many different customers.
Customised products designed to meet the specific needs of a single customer.

3. What is software engineering?
An engineering discipline concerned with all aspects of software production from specification to system maintenance.

4. What are the four fundamental activities in software processes?
Software specification, software development, software validation and software evolution.

5. What is the distinction between computer science and software engineering?
Computer science is concerned with theories and methods of computers and software systems; software engineering is concerned with the practice of software production.

6. What are the 3 general issues that affect many different types of software?
Heterogeneity. Software may have to execute on several different types of system.
Business and social change, which drives requirements for software change.

8. What software engineering fundamentals apply to all types of software systems?
a. Systems should be developed using a managed and understood development process.
b. Dependability and performance are key system characteristics
c. Understanding and managing the software specification and requirements are important.
d. Effective use should be made of available resources.
