Question 1

One phase in system development is _______.

Accepted Answer

System development typically involves multiple phases, including analysis, designing, implementation, testing, and maintenance. However, of the given options, only "analysis" is a recognized phase in system development. This phase typically involves gathering and analyzing requirements and needs to determine the goals and objectives of the system to be developed.

Question 2

Testing a software system can involve _______ testing.

Accepted Answer

Testing a software system can involve both black-box testing (testing from the perspective of an end-user without knowledge of the inner workings of the system) and glass-box testing (testing with knowledge of the internal code and structure of the system). These two approaches can be complementary and provide a more thorough assessment of the system's functionality and performance.

Question 3

In the system development process, writing the program is part of the _______ phase.

Accepted Answer

The implementation phase is when the system is actually developed and written, and is often considered the most time-consuming phase of the system development process. The other options (analysis, design, testing) all come before the implementation phase in the process.

Question 4

Defining the users, requirements, and methods is part of the _______ phase.

Accepted Answer

Defining the users, requirements, and methods is part of the analysis phase in software development. This phase involves gathering and analyzing information to identify the needs and objectives of the software, as well as any potential limitations or constraints that may affect its development.

Question 5

_______ is the breaking up of a large project into smaller parts.

Accepted Answer

Modularization is the process of dividing a large project into smaller modules or components, each of which can be developed and separately maintained. This makes the project more manageable and easier to maintain in the long run.

Question 6

_______ is a measure of how tightly two modules are bound to each other.

Accepted Answer

Coupling is the measure of how much one module relies on another module. It indicates the degree to which two modules are connected to each other. Modularity (A) refers to the degree to which a system's components may be separated and recombined, while interoperability (C) refers to the ability of different systems to communicate with each other. Cohesion (D) refers to the degree to which the components within a single module are related and work together.

Question 7

In the system development process, structure charts are tools used in the _______ phase.

Accepted Answer

Structure charts are used in the design phase of the system development process. It is used to represent the organization of modules and sub-modules of a system, and their interrelationships. The structure chart helps in designing the program logic, ensuring that it meets the requirements of the analysis phase.

Question 8

_________between modules in a software system must be maximized.

Accepted Answer

Cohesion refers to the degree of relatedness of elements within a single module. Therefore, maximizing cohesion leads to better organization within a module and makes it easier to maintain and modify. On the other hand, minimizing coupling between modules can reduce the effects of changes made in one module from affecting others, which makes it easier to modify and maintain individual modules.

Question 9

_________between modules in a software system must be minimized.

Accepted Answer

Coupling refers to the degree of interdependence between modules in a software system. High coupling means modules are tightly dependent on each other, which makes the system harder to modify or maintain. Therefore, minimizing coupling is important to improve software quality and maintainability. Cohesion, on the other hand, refers to the degree to which the elements within a module are functionally related. High cohesion means elements within a module are strongly related, which is desirable for better module design. However, the question specifically asks about minimizing the interdependence between modules, which is related to coupling. Therefore, the best choice is A.
