Explain the following terms (15 Points, 3 Points for Each):(1) User interfaceThe interface between users and the software systems.(2) Software evolutionThe software change in the software life cycle.(3) Software requirementsThe requirements are the descriptions of the software services and constraints that are generated during the requirements engineering process. It may range from a high-level abstract statement of a service or of a system constraint to a detailed mathematical functional specification.(4) System modelA system model is a specification which helps the analyst to understand the functionality of the system and is used to communicate with customers.(5) VerificationAre we building the product right?i.e.the software should conform to its specification.2. Answer the following questions briefly (20 Points, 5 Points for Each):(1) Advantages of incremental development?1. Accelerated delivery of customer services. Each increment delivers the highest priority functionality to the customer.2. User engagement with the system. Users have to be involved in the development which means the system is more likely to meet their requirements and the users are more committed to the system. (2) What is the component-based development?Component-based software engineering (CBSE) is an approach to software development that relies on software reuse. It emerged from the failure of object-oriented development to support effective reuse. Single object classes are too detailed and specific. Components are more abstract than object classes and can be considered to be stand-alone service providers.(3) What is the multiple inheritance?Rather than inheriting the attributes and services from a single parent class, a system which supports multiple inheritance allows object classes to inherit from several super-classes.(4) What is the architectural design?The design process for identifying the sub-systems making up a system and the framework for sub-system control and communication is architectural design.3. Multiple Choices (10 Points, 1 Point for Each):(1) a, (2) d, (3) c, (4) b, (5) a, (6) b, (7) d, (8) a, (9) d, (10) b.4. True or False (10 Points, 1 Point for Each):(1) b, (2) a, (3) a, (4) b, (5) b, (6) b, (7) b, (8) a, (9) a, (10) a.5. (13 Points)It describes the software reengineering process activities:•Source code translation–Convert code to a new language.•Reverse engineering–Analyse the program to understand it;•Program structure improvement–Restructure automatically for understandability;•Program modularisation–Reorganise the program structure;•Data reengineering–Clean-up and restructure system data.6. (12 Points)It describes the Types of composition.(1) Sequential composition where the composed components are executed ininterfaces of each component. composition where onecomponent calls on another.This provides interfaceof one component is composed with the required interface of another. (3) Additive composition where the interfaces of two components are put together to create a new component.7.
