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.
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
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.
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
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
