APCSP TEST QUESTIONS AND ANSWERSHow are procedures abstractions in computer science?
A. They are Blocks of code that do something specific
B. They represent the lowest level of code for the computer to run
C. They use actual values to represent concepts
D. They can be used without understanding or seeing the code used - Answers -D -
abstractions in code are code that is simplified
What do parameters used in a procedure provide?
A. A way to get values into the procedure making code more flexible
B. A way to return values calculated in the procedure back to the calling program
C. A way to call a procedure from within another procedure
D. A way to connect an API to the procedure - Answers -A
What happens when you "clean data"?
A. Corrupt data records are corrected or removed
B. Incomplete data records are completed or removed
C. Duplicate records are removed
D. All of the above - Answers -D - cleaning data is reorganizing and completing files
What causes a problem to be classified as "intractable"?
A. The solution is too inefficient for large datasets
B. There is not an algorithm that can solve it
C. It is solved most efficiently with large datasets
D. Multiple algorithms exist with different levels of efficiency - Answers -A - intractable is
inefficient for large datasets
How do selection statements determine which section of code to execute?
A. Through the use of the Turing algorithm for analysis
B. Through random number generators
C. Through conditions that evaluate true or false
D. Through variables initialized to execute these statements - Answers -C - selection
statements select things - yes or no, true or false
How are list elements accessed individually?
A. The list name plus an integer index in brackets are used
B. The list name is used along with the value the code needs to access
C. The "access" command is used with the list name and length
D. A FOR EACH loop is used with the list to find an individual value - Answers -A
What do logical conditions always evaluate to?
A. A Boolean value
B. A value stored in a constant
C. A "string" text feild
, D. A real number - Answers -A - anything related to logic will be Boolean (true/false,
yes/no)
What is an example of a coding-related abstraction?
A. Using comments in your code
B. The CPU (central processing unit)
C. Pressing a button on an app
D. A constant value - Answers -C - with an abstraction, you don't need to know how it
works
What is the process where algorithms are used with historical data to attempt to predict
human needs or requests for data?
A. Data mining
B. Trend prediction
C. Social analysis
D. Machine learning - Answers -D - with machine learning, you learn from and make
predictions based on trends or previous searches
There are many programming languages. How do computers understand the different
languages?
A. Testing takes care of this for computers by confirming the correctness of the code
B. Debugging handles this for computers by confirming the validity of the code
C. Compilers and interpreters translate code to machine language for computers to read
D. There is a special natural language tied to all programming languages that all
computers can read that is created behind the scenes using abstraction - Answers -C
How is a logic gate an abstraction?
A. It adds the detail needed for each logic condition possible
B. It is more specific than hardware components
C. It represents any true and false condition
D. It is an integrated system of physical components - Answers -C
How do APIs simplify writing programs?
A. By providing step-by-step instructions on how to use the programming language
B. By importing the newly written software to the API for others to use
C. By providing documentation on how to code the needed functionality
D. By connection pre-written and tested software to a new program - Answers -D -
definition of API - Application programming Interfase
Provides prewritten code to use in another coding program
While algorithms can be analyzed mathematically, what information does the empirical
testing process provide?
A. It provides best, worse, and average case information about the algorithm
B. It provides the maximum size dataset the algorithm can handle
C. It provides the validity of the algorithm
