Introduction to IT – D322 WGU – Q/A
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
Evolution of Users ✔️Ans - 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 ✔️Ans - Rules provided by which networks communicate with
each other.
TCP/IP ✔️Ans - Transmission Control Protocol/Internet Protocol. Most
commonly used protocol; is required of all computers that communicate over
the Internet.
Protocol Stack ✔️Ans - A collection of protocols. TCP/IP is an example.
Components of a Computer ✔️Ans - CPU, Memory and Storage,
Peripheral Devices
CPU ✔️Ans - Executes programs' instructions and commands various
components in the computer. Referred to as the "chip".
