QUESTION 1
Information Technology
Answer: The technology used in creating, maintaining, and making information accessible.
Rationale: Information technology encompasses the systems and processes for managing data, including its acquisition,
storage, manipulation, and dissemination. This definition highlights its role in the entire lifecycle of information.
QUESTION 2
IT Professional Roles
Answer: Administration and Support.
Rationale: Information technology roles encompass the management, maintenance, and troubleshooting of computer
systems and networks to ensure operational continuity. This broad category includes tasks like system administration, help
desk support, and network engineering, all focused on keeping technology functioning effectively.
QUESTION 3
Support IT Professionals
Answer: Help desk and training.
Rationale: Effective support for IT professionals necessitates readily available technical assistance through a help desk and
ongoing professional development via training programs. This dual approach ensures immediate problem resolution and
cultivates advanced skill sets, thereby enhancing IT infrastructure efficiency.
QUESTION 4
Information
Answer: Processed data.
Rationale: Information represents data that has been organized, structured, or presented in a meaningful context to
become useful. This transformation from raw data into actionable knowledge is the core principle of information processing.
QUESTION 5
DIKW Hierarchy

, STUDENT STUDY & MASTERY EDITION PRACTICE & REVIEW GUIDE
Figure Q5: Reference Image
Answer: Defines the transition of data to information from knowledge to wisdom. (Data Information
Knowledge Wisdom)
Rationale: The DIKW hierarchy illustrates how raw data is processed into meaningful information, then synthesized into
knowledge, and finally applied with insight to achieve wisdom. This progression highlights the increasing value and context
added at each successive level of understanding.
QUESTION 6
Data in DIKW
Answer: The input directly received by the user (or computer). It is generally not usable until it has been
converted into a relevant form.
Rationale: Data represents raw, unorganized facts and figures that lack context or meaning until processed into
information. The DIKW pyramid posits that data is the foundational element, requiring interpretation and structuring to
become actionable knowledge.
