Intro to IT WGU Module 1-6 Exam 2026
Questions and Answers Graded A+
Application Software - Correct answer-Programs end users run to accomplish tasks
Bandwidth - Correct answer-Transfer rate permissible over the media, and is
described as bps or b/s (bits per second)
**Modern bandwidth is described in millions/billions bits per second (i.e. Mbps or
Gbps)
*Older tech limited to thousands, (i.e. 56 Kbps)
Black Hat - Correct answer-Unethical Hacker
Boolean/Logical - Correct answer-Type of Data.
Ex: True/False (in reply to active subscriber?)
Only two possible answers: yes/no or true/false
Buffer Overflow - Correct answer-Most well known type of software injection
attack.
,Because buffer is limited in size, if software doesn't ensure insertions in buffer are
limited in size, sufficient amounts of malicious code could overflow buffer.
malicious overflow code could then be stored in memory and run to perform
operations inserted by hacker.
Circuit Switch Network - Correct answer-Requires full pathway (or circuit) to be
established and maintained during entire submission.
Ex: Phone network b/c path exists during entire conversation and communication
can be both ways.
Client-Server - Correct answer-Client is computer that will request info from
another computer (the server) .
The server takes requests and responds. *More expensive than peer to peer.
BENEFITS: More storage=faster response time
Cloud Computing - Correct answer-Allows organization to access resources/app
anywhere, anytime. Beneficial because an org. may access resources it may not
normally have
Coaxial Cable - Correct answer-Commonly used network connection.
*Transmits using electromagnetic waves
Database Server - Correct answer-Permits dB access across a network.
,Performs tasks such as data analysis, data manipulation, security, and archiving.
May/may not store database itself.
**MySQL is popular.
Date/Time - Correct answer-Type of Data
Device Drivers - Correct answer-Interface b/w OS and hardware
Email Server - Correct answer-Provides email service. Accepts email request from
clients.
IMAP,POPS,HTTP,MAPI,MIME
Fiber Optic Cable - Correct answer-Transmits via light pulses as opposed to
electromagnetic ones
File Server - Correct answer-Computer with large hard disk storing files, but can
also store software to be run over network
Flat File Database - Correct answer-One large single table without relations
between tables.
*Most common is CSV file (files separated by comma)
*Flat file is used if amount of data is fairly small. Ex: Spreadsheet
Floating Point - Correct answer-Decimal.
, Ex: 4.2
FTP Server - Correct answer-Hosts files and allows clients access to files. Access
is in form of uploading/downloading files. Requires either user has an account or
logs in as anonymous user.
Grey Hat - Correct answer-Both ethical and unethical at times. A fence sitter
Hierarchical Database - Correct answer-Organizes data by using tree-like or
organizational chart type structure.
*Main data points can have multiple sub-data points (Parent/child structure)-
Subpoints can only have one main data point.
*Records can be broken up so one portion is in one location and another is in
another section.
Ex: Employee database could list all employees, but a child relation could contain
info about employee position, pay level, responsibilities. Another child relation
could include info about employee projects. Sub data is always specific to main
data point.
IAS Availability - Correct answer-Requires data/information be available when
needed
