WGU C182 QUESTIONS AND ANSWERS
IT Professional Roles Correct Answer: Administration and Support
System Correct Answer: A combination of independent parts all working together to accomplish a
certain goal.
Information Technology Correct Answer: The technology used in creating, maintaining, and making
information accessible, which includes the software, data and computer networks.
System Administrator Correct Answer: Maintains all aspects of the system including hardware, software
(OS), and programming.
Network Administrator Correct Answer: In charge of all aspects of the computer network (routers and
switches).
Database Administrator Correct Answer: Focuses on the design, development, and support of database
management systems (DBMSs). Also, integration of data from older systems to new ones.
Security Administrator Correct Answer: Installs, configures, and administers firewall security to protect
systems and proactively work to stop intrusions.
Web Administrator Correct Answer: Installs, configures, maintains, secures, and troubleshoots web
severs. (Webmasters)
Support IT Professionals Correct Answer: Help desk and training (create docs, helpful websites, training
sessions).
IT Personnel Correct Answer: Install, test, and update software; process data into information, develop
fast computer chips.
Information Correct Answer: Processed data.
DIKW Hierarchy (Data Information Knowledge Wisdom) Correct Answer: Defines the transition of data
to information to knowledge to wisdom.
Data in DIKW Correct Answer: The input directly received by the user (or computer). It is generally not
usable until it has been converted into a relevant form.
Information in DIKW Correct Answer: Having been inferred from data; one or more processes have
been applied to the data to transform it into a more useful form.
Knowledge in DIKW Correct Answer: 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.
,Wisdom in DIKW Correct Answer: Provides a social setting to knowledge; an understanding of the
"why". Can only come by having both knowledge and experience.
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.
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
IPOS Correct Answer: The Input-Procession-Output-Storage Cycle
Input Correct Answer: Raw data is entered by the user.
Processing Correct Answer: Raw data is organized or structured for usefulness.
Output Correct Answer: Information is output so user can see results.
Storage Correct Answer: Processed information is stored for permanent record.
Computer System Correct Answer: A collection of components that work together to meet the needs of
the user; typically categorized as either hardware, software, networks, or users.
Hardware Correct Answer: Physical components of a computer system which include the system unit
and its components and peripheral devices; tangible aspects of the computer.
Software Correct Answer: Computer programs that tell the computer what to do--how to execute
commands and process information
Network Correct Answer: A collection of computers and resources connected by various media so that
they can communicate with each other.
User Correct Answer: Those who use a computer.
Software Categories Correct Answer: Systems Software and Applications Software
, Evolution of Users Correct Answer: 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.
Protocol Correct Answer: Rules provided by which networks communicate with each other.
TCP/IP Correct Answer: Transmission Control Protocol/Internet Protocol. Most commonly used
protocol; is required of all computers that communicate over the Internet.
Protocol Stack Correct Answer: A collection of protocols. TCP/IP is an example.
Components of a Computer Correct Answer: CPU, Memory and Storage, Peripheral Devices
CPU Correct Answer: Executes programs' instructions and commands various components in the
computer. Referred to as the "chip".
Memory Correct Answer: Stores the programs being executed and the data they are using.
I/O Subsystem Correct Answer: All peripheral devices where long term storage devices are used.
Bus Correct Answer: Permits information to move between each component; electrical channels that
enable communication among the electronic components
System Unit Correct Answer: 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.
Internal Components of the System Unit Correct Answer: Case, Internal Bays, Buses, Ports, Hard Drive,
Motherboard, CPU, CPU Cooler, Memory Module (RAM), Power Supply Unit (PSU), Expansion
Slots/Cards
Parts of the CPU Correct Answer: 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
System Clock Correct Answer: Controls the speed at which instructions are processed.
RAM Correct Answer: Stands for Random Access Memory.
It temporarily stores data before it is processed and sent to your screen or printer.
It is volatile (means data or information stored disappears when the computer is turned off or loses
power).
You can choose the amount of RAM your computer has.
