AP CSP Review 1

How are procedures (functions) 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 the 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 to the procedure

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 not 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 (Internet Service Provider)

Why do we have high-level programming languages?

• To make it easier for 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.

How do selection statements determine which section of code to execute?

• Through the use of the Turing algorithm for analysis

• Through random number generators

• Through conditions that evaluate to true or false

• Through variables initialized to execute these statements

What do logical conditions always evaluate to?

• A Boolean value

• A value stored in a constant

• A "string" text field

• A real number

What is an example of a coding-related abstraction?

• Using comments in your code

• The CPU (Central Processing Unit)

• Pressing a button on an app

• A constant value

There are many programming languages. How do computers understand the different languages?

• Testing takes care of this for computers by confirming the correctness of the code.

• Debugging handles this for computers by confirming the validity of code

• Compilers and interpreters translate the code to machine language for computers to read

• There is a special natural language tied to all programming languages that all computers can read that is created behind the scenes using abstraction
