WGU D075 OA TEST PAPER 2026 COMPLETE
QUESTIONS WITH SOLUTIONS VERIFIED A+
● Information Technology (IT) - The study, design, development,
implementation, support, and management of computer-based
information systems, particularly software and hardware.
● best practice - A management process, technique, or method that is
most effective at arriving at a desired outcome or better outcome than
any other process, technique, or method.
● The most effective way of arriving at a desired outcome - What is the
definition of the term "best practice"?
● Computing processing power doubles every 18 months - Which
observation about computing technology is expressed in Moore's law?
● CPU - What hardware component performs most of the calculations
for a computer?
● Hypertext Markup Language (HTML) - Language used to compose
Web pages.
,● Hypertext Transfer Protocol (HTTP) - protocol used to defines how
messages are formatted and transmitted on the internet.
● Mainframe computers - Massive, room-sized computers that process
and store enormous amounts of bulk data and information
● Midrange Computers - less powerful and smaller in physical size than
mainframe computers, but do many of the same things, simply on a
smaller scale
● Microcomputer - The least Powerful computers in terms of processing
and come in for typical configurations: Desktop, laptop, tablet, and
handheld.
● system software - Software that runs in the background and requires
very little or no user intervention.
● Application software - Software that is designed for the user to carry
out a specific task.
● Hardware - the physical parts of a computer
● Software - a collection of computer programs that accomplish a
specific task.
,● Operating System (OS) - A collection of Computer programs that
work together to manage hardware and software to ensure that they are
working properly. Also Called a platform.
● Graphical User Interface (GUI) - The visual system of a computer
screen designs that a user to interact with an electron it
● Process - Any task a computer performs.
● Cache - A hardware or software component that stores data so that
future requests for that data can be served faster.
● Random Access Memory (RAM) - A type of memory that allows data
to be accessed in any order without physical movement of the silicone
media.
● Registers - A location in a store of data used for a specific purpose and
with quick access time.
● Virtual Memory - Memory that appears to exist as main storage
although most of it is supported by data held in secondary storage,
transfer between the two being made automatically as required.
, ● Solid State Drive (SSD) - Device that uses integrated circuit
assemblies as memory to store data persistently, typically using flash
memory.
● Disk Storage - Non-volatile, secondary storage that is recorded to a
physical device like a hard drive or optical disk with a read/write
apparatus.
● Optical disk - A computer desk that uses optical storage techniques
and technology to read and write data.
● File Allocation Table (FAT) - A table of contacts that directs the
read/write Arm of the hard drive to the location where data exist and
access is the data upon the users request.
● word processor - An application software you use to create, compose,
edit, format, and print documents.
● Database Management System (DBMS) - An application software that
is used to create a collection of related files that consist of records of
data separated by fields can be queried to produce populations of
information.
● presentation software - And application software used to present
information in a slideshow format.
