WGU D684 - SECTION 1 EXAM TEST QUIZZES &
ANSWERS GRADED A+ 2025
Which value is stored as an integer in computer programming? - Answer- 21. Rationale: The
integer data type is used to represent positive or negative whole numbers without fractional parts.
Which coding construct repeats a task while a condition is true? - Answer- Iteration. Rationale:
The iteration construct, or the looping construct, uses a while statement to perform the same task
over and over again as long as the condition is true.
How are items accessed in a stack? - Answer- The last item to be added becomes the first item
removed (LIFO). Rationale: A stack is an ordered group of items that can only be accessed at
one end, called the top of the stack. Items can be pushed onto and popped off of this end.
Therefore, the last item to be added becomes the first item removed.
A web browser puts websites into a viewing history log and accesses the most recent one when
the back button is clicked. Which data structure would be appropriate for this situation? -
Answer- Stack. Rationale: A stack is an ordered group of items that can only be accessed at one
end, called the top of the stack. Items can be pushed onto and popped off of this end. In this case,
the only item needing to be accessed is the most recently added item. Therefore, a stack is most
appropriate for storing the data.
What is the relationship between a parameter and an argument? - Answer- A parameter is a
temporary variable in a function that receives the actual value of an argument. Rationale: A
parameter is defined within a function and serves as a temporary placeholder. The argument is
the actual value that is passed to the function and gets temporarily stored in the parameter.
Which programming language is considered to be a declarative language? - Answer- Lisp - The
declarative programming paradigm is a model in which the results are described, but the steps to
accomplish the results are not stated. There are two basic models within this paradigm,
functional and logical. Lisp is an example of declarative.
What does a technology company need to commit to if adopting the Institute of Electrical
and Electronics Engineers (IEEE) Code of Ethics?
,maintain & improve technical competency
Accept and provide appropriate professional review
Respect privacy and honor confidentiality
Ensure that a single person is awarded a patent for any new invention
Maintain and improve technical competence
Which situation represents a violation of the Codes of Ethics for both the Association of
Computing Machinery (ACM) and the Institute of Electrical and Electronics Engineers
(IEEE)?
An executive eliminates all professional development opportunities for employees.
The location of a computer is given by either falcon.csc.computersoft.org or 205.39.155.18.
Which part of this information is known as the hostname?
falcon.csc.computersoft.org
Which piece of pseudocode correctly calculates the integer result of dividing the integer b
by the integer f?
b // f
26.A programmer has been asked to lead a project that uses artificial intelligence to search
for patterns in Wi-Fi signals to improve efficiency and range. The programmer will use the
software development lifecycle (SDLC) as a model for design and implementation. Which
step is the programmer in when using flowcharts and pseudocode to help describe the
intended steps for the program?
Plan the logic
What is the name of the variable type used to represent a real number?
float
What is the name of a parameter that prevents a function from changing the content of an
argument?
Value
Which component is considered a major part of the von Neumann architecture?
control unit
A particular algorithm sorts data by building the final sorted list one item at a time,
placing each new item into its correct position. Which word is associated with this
algorithm?
Insertion sort
Which storage device typically offers the fastest data access speed?
,ssd
Solid state drive (SSD)
USB flash drive
Hard disk drive (HDD)
Optical drive
A computer programmer needs to find the result of subtracting the value d from the value
f. What is the pseudocode that will accomplish this?
f-d
subtract d from f
sub(f, d)
set b = f - d
f-d
What is the pseudocode that will convert the integer a to a floating point number?
myFloat x = float(a)
What is the name of the resource management technique in which processes and memory
are both divided into separate, fixed-size pieces?
paged
What is one example of a high-level network application protocol?
SMTP
Thunderbolt
HDMI
SMTP
Lightning
Which term indicates a file access technique in which files are conceptually divided into
numbered logical records?
DIRECT
Which characteristic describes the binary algorithm?
It keeps resetting at the middle
Which term refers to the number of bits a computer can process at one time?
bus width
What is the main advantage of using a nesting structure in pseudocode?
, It allows for more complex decision-making and iterations.
A computer's location on a network is given by either jenkins.develocorp.org or
192.158.1.38. What is the computer name in this scenario?
jenkins
Which data structure is it in which the item removed is the one that has been in the longest
time?
queue
Array
Queue
List
Stack
analog data
data represented in a continuous and variable form
American Standard Code for Information Interchange (ASCII)
a standard encoding system for text characters that uses numeric values to represent letters,
numbers, and symbols
bandwidth
the maximum rate of data transfer across a network or communication channel, usually measured
in bits per second
binary
a numerical system that uses only two digits, zero and one, to represent data in computing
Boolean expression
a logical statement that can only be true or false and uses operators like AND, OR, and NOT
character
a single letter, digit, or symbol used in writing text
character set
a collection of characters that a computer can recognize and process, like ASCII or Unicode
compression ratio: the ratio of the original data size to the compressed data size, indicating how
much the data has been reduced
control structure
