WGU C182 Introduction to IT
Information Technology ANS: The technology used in creating, maintaining, and making information
accessible.
IT Professional Roles ANS: Administration and Support
System Administrator ANS: Maintains all aspects of the system including hardware, software, and
programming.
Network Administrator ANS: In charge of all aspects of the computer network
Database Administrator ANS: Focuses on the design, development, and support of database
management systems (DBMSs).
Security Administrator ANS: Installs, configures, and administers firewall security to protect systems
and proactively work to stop intrusions.
Web Administrator ANS: Installs, configures, maintains, secures, and troubleshoots web severs.
Support IT Professionals ANS: Help desk and training.
Information ANS: Processed data.
DIKW Hierarchy ANS: Defines the transition of data to information from knowledge to wisdom. (Data
Information Knowledge Wisdom)
Data in DIKW ANS: 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 ANS: 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 ANS: 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 ANS: Provides a social setting to knowledge; an understanding of the "why". Can only
come by having both knowledge and experience.
Information Systems ANS: 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 ANS: 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 ANS: The Input-Procession-Output-Storage Cycle
Input ANS: Raw data is entered by the user.
Processing ANS: Raw data is organized or structured for usefulness.
Output ANS: Information is output so user can see results.
Storage ANS: Processed information is stored for permanent record.
Computer System ANS: A collection of components that work together to meet the needs of the user;
typically categorized as either hardware, software, networks, or users.
Hardware ANS: Physical components of a computer system which include the system unit and its
components and peripheral devices; tangible aspects of the computer.
Software ANS: Computer programs that tell the computer what to do--how to execute commands and
process information
Network ANS: A collection of computers and resources connected by various media so that they can
communicate with each other.
User ANS: Those who use a computer.
Software Categories ANS: Systems Software and Applications Software
