APCSP Test Questions And Answers With Verified Solutions

How 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 - Answer-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 - Answer-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 - Answer-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 - Answer-A - intractable is inefficient for large datasets What are statements, procedures and libraries examples of?A. Low-level machine code that the computer uses to run the code B. Abstractions used in writing software because they can be used without knowing the details of how they work C. Algorithms that provide suggestions on how to approach writing code to solve a problem D. Pseudo code that helps design a solution for coding challenges - Answer-B - these are all abstractions What is an issue that organizations must handle when dealing with large datasets? A. Ensuring enough staff are on hand to process the data B. Ensuring the bandwidth can handle the processing of the data C. Ensuring the people's private data is not exposed D. Ensuring the system can scale down after the data is sent to the cloud - Answer-C
