AP CSP Final Review

Front

How do computing devices represent information?

Back

A computer represents data as bits which is either a 0 or a 1

Front

Which of the following binary (base-2) numbers is LARGEST? 11000000, 01111111, 00000001, 10111111

Back

11000000

Front

How many total numbers can be represented with an 8-bit binary (base-2) system?

Back

256

Front

Which of the following is true of lossy and lossless compression algorithms?

Back

Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data.

Front

Ryan is designing an app that needs to quickly send low quality photos between users. Most smartphones take much higher quality photos than Ryan needs for his app. Which type of compression should Ryan choose and why?

Back

Lossy compression since it typically results in smaller data sizes.

Front

Who owns the photo Arman took and posted online, which Beatrice copied to her website with a Creative Commons license?

Back

Arman owns the photo because he was the original creator and did not license the work.

Front

This diagram shows a number of computing devices connected to the Internet with each line representing a direct connection. What is the MINIMUM number of paths that would need to be broken to prevent Computing Device A from connecting with Computing Device E?

Back

3

Front

Two devices are connected to the Internet and communicating with one another. A squirrel chews through one of the wires in the network that is currently being used by the devices to communicate. The network immediately begins using a different path through the network and communication continues as normal. This situation best exemplifies which principle?

Back

fault-tolerance

Front

What is MOST likely to be an outcome of the digital divide?

Back

People from some racial or ethnic groups have unequal access to computing technology.

Front

Which actions are helpful in designing and developing an app? I. Interviewing potential users of the app II. Writing the entire program code before testing any part of it III. Observing users attempting to use the app

Back

I and III only
