Intro to IT WGU Module 1-6 Question
and answers 100% correct 2026
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
IAS Confidentiality - correct answer Requires data be kept secure so that it does not fall to unauthorized
users.
It goes beyond security measures and extends to policies. Security measures should extend beyond
network. A stolen laptop should not violate confidentiality
, IAS Integrity - correct answer Requires data are correct.
Requires 3 different efforts:
1. Data gathering should include an accuracy component.
2. Data must be entered into system accurately.
3. Once data is in dB, changes made will leave a record of when the change was made and by whom.
Information Security Assurance Goals - correct answer "CIA"
1. Confidentiality
2. Integrity
3. Availability
Internet Usage Software - correct answer Email, FTP, Client, Web Browser
Intranet - correct answer A LAN that uses IP. Used to communicate within an organization
Kernel - correct answer Core component of OS.
Loads when computer first boots.
Sits on top of hardware, is interface b/w hardware and software
Local Application - correct answer Software stored on an individual computer
Network Hub - correct answer Device that connects multiple computers together.
*Broadcasts to all connected devices, even if message is intended for just one.

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)
