Question 2

In the extreme programming environment, _____ programming allows programmers to detect and correct programming mistakes as they go, which is faster than correcting them after an entire program has been written.
A)procedural
B)pair
C)sequential
D)parallel

Accepted Answer

Pair programming, a technique used in extreme programming, involves two programmers working together at one workstation. One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently. This collaboration enables immediate feedback and error detection, which is more efficient than finding and fixing errors after the full program is developed.

Question 3

Question 6

The fundamental principle behind _____ is that the self-contained blocks of codes can be reused in a variety of different applications, allowing new business processes to be created from a pool of existing services.
A)rapid prototyping
B)joint application design
C)service-oriented architecture
D)computer-aided systems engineering

Accepted Answer

The fundamental principle behind service-oriented architecture (SOA) is that it allows for the reuse of self-contained blocks of code across different applications, enabling the creation of new business processes from existing services. This architecture style is designed to enhance the flexibility and reuse of IT resources.

Question 11

A _____ is a tool used in the structured systems analysis and design (SSAD)model for data analysis.
A)conceptual data model
B)context diagram
C)flowchart
D)data flow diagram

Accepted Answer

A conceptual data model is a tool used in the structured systems analysis and design (SSAD) model for data analysis. It is a graphical representation of the data entities and their relationships within a system.

Question 12

_____ are small-scale versions of information systems, which are built before building the entire system, and are used to illustrate the system's benefits and allow users to offer feedback.
A)Structured systems
B)Prototypes
C)Flowcharts
D)Context diagrams

Accepted Answer

Prototypes are small-scale versions of information systems created as a preliminary model to demonstrate the system's features, benefits, and to gather user feedback before developing the full system.
