C724 (Information Systems Management) –
WGU questions and answers
Information Policy Administrator - ANSWER- Responsible for acquiring,
organizing, and distributing organizational information internally.
Data Dictionary - ANSWER- Stores and manages all of the information about
the database, or the metadata.
Three V's of Big Data - ANSWER- Volume, Variety, and Velocity; Volume
refers to the amount of data, variety refers to the number of types of data, and
velocity refers to the speed of data processing (real-time analytics).
Health Analytics Tools - ANSWER- through smartphone sensors or wearable
peripheral devices. Data from these devices is collected, analyzed, and used to
help a user to understand, improve, and maintain, or automatically report, their
health to their health professionals.
Geographic Information Systems (GIS) - ANSWER- Using connections to
numerous databases containing data concerning locations, crimes, taxes, traffic,
votes, and environmental and life science data, geospatial analysis can help
government administrators to understand demographic trends, population
density changes, attribute concentrations
wide area network (WAN) - ANSWER- connection b/w small networks that
create a large network that typically connects business campuses consisting of
computer systems across large distances
Voice over Internet Protocol (VoIP) - ANSWER- VoIP is a type of broadband
application, similar to video, in which voice calls are transmitted over the
Internet.
Public Switch Telephone Network (PSTN) - ANSWER- The entire
interconnected voice telephone network around the world. It is switched based.
,Protocols - ANSWER- used to ensure the quality and accuracy of the
transmission, and that the transmission is understood by the receiving device.
Bridge - ANSWER- a device that connects and passes packets between two
network segments that use the same communications protocol; can be used to
boost Wi-Fi strength in areas of low signal quality.
router - ANSWER- used to connect multiple networks together and forward
data packets between those separate networks to the destination host.
Core Router - ANSWER- A more powerful router that is used to optimize high
volume transmissions; aggregate data from business and transmit the data
directly to the Internet backbone.
Digital Signal - ANSWER- a signal that is being used to represent data as a
sequence of discrete values
Simple Mail Transfer Protocol (SMTP) - ANSWER- Used to manage and
monitor emails that we receive.
Packet Switching - ANSWER- a mode of data transmission in which a message
is broken into a number of discrete, parsed parts that are sent independently in
encapsulated packets, over whatever route is optimum for each packet, and
reassembled at the destination; what is used when accessing the Internet
Circuit Switching - ANSWER- ideal for communications that require data to be
transmitted in real-time; a constant connection is required before transmission
begins.
Repeaters - ANSWER- Receive and retransmit/amplify data at a higher power
to it can go a longer distance.
, Tangible User Interface - ANSWER- An interface in which a person interacts
with digital information through the physical environment
Virtual Network - ANSWER- Create peer-to-peer connections between
computers.
mesh network - ANSWER- network topology in which each node relays data
for the network
TCP/IP - ANSWER- most common protocol which establishes the connection,
and data packet quality transmission. The first two bytes are assigned by the
Internet Service Provider (ISP), and the last two bytes are assigned by the client.
Open System Interconnection (OSI) - ANSWER- consists of seven layers and is
an international standard that governs or guides the development of data
communication protocols
the seven layers are: application, presentation, session, transport, network, data
link, and physical.
Telecommunications Network - ANSWER- Enables the exchange of
information
Executive information system - ANSWER- A system that facilitates and
supports senior managerial decisions.
