1. A is a formal procedure for producing some result.2. A : a series of steps involving activities, constraints, and resources that produce an intended output of some kind.3. The project budget pays for several types of costs: , staff, methods, and tools.4. A prototype is software that is developed to learn more about a problem or about a proposed solution, and that is never intended to be part of the delivered software.5. A is an expression of desired behavior.6. A codifies design decisions and best practices for solving a particular design problem according to design principles.7. No matter what language is used, each program component involves at least three major aspects: control structures, ,and data structures.8. Software is the probability that a system is operating successfully according to specification at a given point in time.9. There are four steps in testing a system: testing, performance testing, acceptance testing, installation testing.10. There are four types of maintenance activities: corrective maintenance, perfective maintenance, preventive maintenance, maintenance.1.
