software engineering set 2 Detailed Explanation And More Example

Question : 1

Fault is

a) It is the process of modifying the state space of the system so that the effects of the fault are minimized and system can continue in operation in some degraded state.

b) Capacity of a system or component to continue normal operation despite the presence of hardware or software faults.

c) It is the widely used hazard technique

d) Incorrect step, process, or data definition in a computer program

Question : 2

Bottom-up testing

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.

Question : 3

User documentation defines

a) Computer program

b) Computer system

c) Use of computer systems

d) Structure of computer system

Question : 4

Validation plan describes

a) Quality procedure

b) Schedule procedure

c) Management procedure

d) None of these

Question : 5

Retrospective Fault detection is

a) Reason for a computer program to resume execution after a failure, using status and results recorded at a checkpoint.

b) Period of time in the software life cycle during which support for a software product is terminated.

c) The fault detection mechanism is initiated after the system state has been changed to check if a fault has occurred*

d) None of these

Question : 6

Which is the correct order ?

a) System development ? system installation ? system operation

b) System installation ? system operation? system development

c) System decomposition? system installation ? system design

d) None of these.
