software engineering set 3 Detailed Explanation And More Example

Question : 1

Lehman’s First Law (Lehman and Belady 1985) is

a) Continuing change: A program used in real-world environment must change necessarily or become progressively less useful in that environment.

b) Increase complexity: As an evolving program change, its strictures tend to become more complex. Extra resources must be devoted to preserving and simplifying the structure.

c) Large program evolution: Program evolution is a self-regulating process.

d) None of these

Question : 2

Cost of maintenance

a) Process of estimating the costs associated with software development projects that include the effort, time, and labor required.

b) Overall cost of maintaining a computer system that includes the costs associated with personnel/training/ maintenance of hardware and software/ requirements growth.

c) Overall cost of operating a computer system that includes the costs associated with personnel / training / system operations.

d) Overall cost of a computer system to an organization that includes the costs associated with operating/ maintaining the system, and the lifetime of operational use of the system.

Question : 3

In system models, object is

a) An entity that has a state and defined set of operations that operates on that state

b) Software program

c) Programming language, that develops any given program

d) None of these

Question : 4

A control model where one system component is designed as system manager which controls the starting, stopping and coordination other system processes can be referred as

a) Manager control model

b) Object oriented model

c) Event driven control model

d) None of these

Question : 5

Match the following : A- Maintenance control: B-Maintenance measures: C-Maintenance personnel : 1-Cost of planning and scheduling hardware preventive maintenance, and software maintenance and upgrades, managing the hardware and software baselines, and providing response for hardware corrective maintenance. 2- Measures that address how easily a system can be repaired or changed. 3-Number of personnel needed to maintain all aspects of a computer system, including the support personnel and facilities needed to support that activity.

a) A-1, B-3,C-2

Question : 6

Exception is

a) Trustworthiness with which a system or component can be modified to take advantage of new software or hardware technologies.

b) An error of some kind or an unexpected event occurs during the execution of a program

c) Here the objective of the process is to work with uses to explore their requirement and deliver a final system.

d) Possible loss or harm in computing system.
