Q1 QUESTION 1 OF 255
Information Technology
CORRECT ANSWER
The technology used in creating, maintaining, and making information accessible.
RATIONALE
Information technology encompasses the tools and systems that facilitate the creation, storage, and dissemination
of data, emphasizing the importance of accessibility and management in a digital environment. This principle
underscores the integral role of technology in enhancing communication and operational efficiency across various
sectors.
Q2 QUESTION 2 OF 255
Information
CORRECT ANSWER
Processed data.
RATIONALE
Processed data results from the organization, analysis, and interpretation of raw data, transforming it into
meaningful information that supports decision-making. This principle underlines the distinction between raw data,
which lacks context, and information that conveys insights and knowledge.
Q3 QUESTION 3 OF 255
Page 2
,Information Systems
CORRECT ANSWER
A collection of data and information used to support the management of an organization. Also refers to the
technical components and human resources that enable the assembly, storage, and processing of data and the
delivery of information. This has existed for a lot longer than computers.
RATIONALE
Information systems encompass both the technical infrastructure and human elements that facilitate data
collection, processing, and dissemination to support organizational management. This broad definition underscores
the historical context of information management, predating modern computing technology.
Q4 QUESTION 4 OF 255
Characteristics of Quality Data
CORRECT ANSWER
Relevance - the data being used must apply directly to the decision being made
Timely - data must be efficient and must be provided in a timely manner
Thorough - the data must be complete
Accurate - data should be captured only once, where possible and should be captured as close to the point of
activity as possible.
Reliable - data should reflect stable and consistent data collection processes across collections points and
over time
RATIONALE
Quality data is characterized by its relevance, timeliness, thoroughness, accuracy, and reliability, which ensure that
decisions are based on complete and consistent information, thereby enhancing the effectiveness of data-driven
decision-making processes. This principle underscores the necessity for data to be applicable and precise,
collected systematically to support informed actions.
Q5 QUESTION 5 OF 255
Object Oriented Programming
CORRECT ANSWER
Characterized by the creation of windowed operating systems, easier real-world object modeling in
programming code, and the application of inheritance in program code.
Page 3
, RATIONALE
Object-oriented programming enhances code organization and reusability through encapsulation, inheritance, and
polymorphism, allowing developers to model real-world entities more intuitively. This paradigm facilitates the
creation of complex systems by structuring code into objects that represent both data and behavior, streamlining
software development.
Q6 QUESTION 6 OF 255
Domain Name Parts
CORRECT ANSWER
Top level domain (TLD) name and Host name
RATIONALE
org, while the host name specifies the individual server within that domain. Understanding this hierarchy is critical
for grasping how domain names function in the Domain Name System (DNS).
Q7 QUESTION 7 OF 255
Application Software
CORRECT ANSWER
Consists of programs that end users run to accomplish tasks
RATIONALE
Application software refers to a category of programs designed specifically for end users to perform tasks such as
word processing, data management, or graphic design, distinguishing it from system software that manages
hardware resources. This definition highlights the user-centric focus of application software in facilitating specific
functionalities.
Q8 QUESTION 8 OF 255
System Software
CORRECT ANSWER
Consists of programs that make up the OS; software that directly supports the computer system itself
