WGU D322 UPDATED ACTUAL QUESTIONS AND CORRECT ANSWERS
VERIFIED 2027 EDITION
1. Information Technology
The technology used in creating, maintaining, and making information accessible.
2. IT Professional Roles
Administration and Support
3. System Administrator
Maintains all aspects of the system including hardware, software, and programming.
4. Network Administrator
In charge of all aspects of the computer network
5. Database Administrator
Focuses on the design, development, and support of database management systems (DBMSs).
6. Security Administrator
Installs, configures, and administers firewall security to protect systems and proactively work to stop
intrusions.
7. Web Administrator
Installs, configures, maintains, secures, and troubleshoots web severs.
8. Support IT Professionals
Help desk and training.
9. Information
Processed data.
10. DIKW Hierarchy
Defines the transition of data to information from knowledge to wisdom. (Data Information Knowledge
Wisdom)
11. Data in DIKW
The input directly received by the user (or computer). It is generally not usable until it has been converted
into a relevant form.
12. Information in DIKW
Having been inferred from data; one or more processes have been applied to the data to transform it into
a more useful form.
1
,13. Knowledge in DIKW
Information that has been put to use; information placed into a context. Refined information such that the
user of the knowledge is able to call forth only relevant portions of information when needed.
14. Wisdom in DIKW
Provides a social setting to knowledge; an understanding of the "why". Can only come by having both
knowledge and experience.
15. Information Systems
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.
16. Characteristics of Quality Data
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
17. IPOS
The Input-Procession-Output-Storage Cycle
18. Input
Raw data is entered by the user.
19. Processing
Raw data is organized or structured for usefulness.
20. Output
Information is output so user can see results.
21. Storage
Processed information is stored for permanent record.
22. Computer System
A collection of components that work together to meet the needs of the user; typically categorized as
either hardware, software, networks, or users.
23. Hardware
Physical components of a computer system which include the system unit and its components and
peripheral devices; tangible aspects of the computer.
24. Software
Computer programs that tell the computer what to do--how to execute commands and process
information
25. Network
A collection of computers and resources connected by various media so that they can communicate with
each other.
26. User
Those who use a computer.
2
, 27. Software Categories
Systems Software and Applications Software
28. Evolution of Users
First users were the engineers who built and programmed computers, then employees who had received
specialized training were users, and now today, anyone and everyone can be a user.
29. Protocol
Rules provided by which networks communicate with each other.
30. TCP/IP
Transmission Control Protocol/Internet Protocol. Most commonly used protocol; is required of all
computers that communicate over the Internet.
31. Protocol Stack
A collection of protocols. TCP/IP is an example.
32. Components of a Computer
CPU, Memory and Storage, Peripheral Devices
33. CPU
Executes programs' instructions and commands various components in the computer. Referred to as the
"chip".
34. Memory
Stores the programs being executed and the data they are using.
35. I/O Subsystem
All peripheral devices where long term storage devices are used.
36. Bus
Permits information to move between each component; electrical channels that enable communication
among the electronic components
37. System Unit
Critical component of all computer based systems; consists of most of the hardware the computer needs
in order to run; comes in a variety of shapes and sizes.
38. Internal Components of the System Unit
Case, Internal Bays, Buses, Ports, Hard Drive, Motherboard, CPU, CPU Cooler, Memory Module (RAM),
Power Supply Unit (PSU), Expansion Slots/Cards
39. Parts of the CPU
Control Unit (CU) - retrieves the instructions and the raw data that is input and coordinates or controls the
sending of those instructions and data to the ALU Arithmetic Logic Unit (ALU) - does the actual processing
of the data; completing mathematical calculations and logical operations to process the data and
converting the input of the keyboard text entry to output displayed on the screen
40. System Clock
Controls the speed at which instructions are processed.
