AP CSP Diagnostic Exam Part 1 of 5

How are procedures abstractions in computer science?

• They are blocks of code that do something specific.

• They represent the lowest level of code for the computer to run.

• They use actual values to represent concepts.

• They can be used without understanding or seeing the code used.

What do parameters used in a procedure provide?

• A way to get values into the procedure making code more flexible.

• A way to return values calculated in the procedure back to the calling program.

• A way to call a procedure from within another procedure.

• A way to connect an API on the procedure.

What happens when you "Clean Data"?

• Corrupt data records are corrected or removed.

• Incomplete data records are completed or removed.

• Duplicate records are removed.

• All of the above

What causes a problem to be classified as "intractable"?

• The solution is too inefficient for large datasets.

• There is not an algorithm that can solve it.

• It is solved most efficiently with large datasets.

• Multiple algorithms exist with different levels of efficiency.

What are statements, procedures, and libraries examples of?

• Low-level machine code that the computer uses to run the code.

• Abstractions used in writing software because they can be used without knowing the details of how they work.

• Algorithms that provide suggestions on how to apporach writing the code to solve a problem.

• Pseudocode that helps design a solution for coding challenges.

What is an issue that organizations must handle when dealing with large datasets?

• Ensuring enough staff are on hand to process the data.

• Ensuring the bandwidth can handle the processing of the data.

• Ensuring that people's private data is now exposed.

• Ensuring the system can scale down after the data are sent to the cloud.

How does the Internet work with the different equipment in use?

• The routers adjust for the different equipment manufacturers by sending data on the same equipment brands.

• Specific companies are approved to make equipment for the Internet.

• Vendors follow the protocols established to enable data to be sent and received across any equipment.

• The server farms handle the data once the data reach the Regional ISP.

What does scalability mean?

• The ability to build additonal functionality into the hardware.

• The ability to build additional functionality into the software.

• The ability to add more features to the hardware.

• The ability to add or remove resources as the size changes.

Why do we have high-level programming languages?

• To make it easier fore people to write code.

• So code will compile faster increasing efficiency.

• To make code reusable to speed development time.

• To prevent errors in programs.

How can an image of a house that is used in a program represent an abstraction?

• When pressed, code will run to return your screen to the home page.

• The program directions to drive to your house will be displayed on your device.

• Data about the smart features of your house will be displayed.

• All of the above.
