Question : 1

A class room in a school is a

a) System

b) Sub-system

c) Module

d) None of these

Question : 2

Match the following: A- Formal mathematical transformation: B- Formal process model: C-Formal Specifications: D-Formal System development: 1- Here the formal mathematical representation of the system takes place. 2- It is a starting point for process analysis. It is abstract and only defines the principal process activities and deliverables. 3-Specifications expressed in a language whose vocabulary, syntax and semantics are formally defined. 4-It is more common to waterfall model, but here the development process is based on formal mathematical transformation of a system specification to an exactable program.

c) A-2,B-1,C-3,D-4

d) A-1,B-3,C-2,D-4

Question : 3

a) Active object

b) Servers

c) Modules

d) None of these

Question : 4

System is

a) The set of system services and constraints in details

b) System functions that restricts the use of objects to certain users.

c) Purposeful collection of interrelated components that work together to achieve some objective.

d) None of these

Question : 5

Software implementation is

a) It is concern with modification of existing system to meet changing requirements.

b) It is a process of converting system specifications into an executable system.

c) It analyzes and checks system representation such as the requirements document, design diagrams and program source code.

d) None of these

Question : 6

In Call-return control model

a) The low-level components of a system are integrated and tested before the higher-level components have been developed.

b) The testing process starts with modules at lower levels in the hierarchy and works up the hierarchy of modules until the final module is tested.

c) An event driven control system, where an event is broadcasted to each subsystem and any sub-system that can handle that event responds to it.

d) Control starts of the top of a sub routine hierarchy and through sub routine calls passes to lower levels
