A computer processes data one step at a time in the given 1, 2, 3, 4 order.

Which question about whale tracking data cannot be answered with the collected data?

Does the animal travel in groups with other tracked animals?

What method is used to predict future usage based on large data sets?

Using past purchases to recommend products for possible purchase.

What metadata is associated with sending an SMS message?

The time the message was sent and received, the geographic location of the sender and receiver, and the phone number of both the sender and receiver.

Which information cannot be determined from Spotify's metadata?

Which prediction about an object's fall time in a vacuum is correct?

Mass has no effect on time for an object to fall 1 meter in a vacuum.

What is a uniquely useful feature of search engines?

The ability to find and filter information from a large variety of sites.

How do online systems with large data sets benefit from scalability?

If the workload increases, it can mitigate performance decreases.

What is a common reason for an overflow error in a system?

Exceeding the maximum number representable in the bit system.

Which of the following is a benefit of using high-level programming languages?

They are closer to natural language, which makes them easier to read.

What are the characteristics of digital data?

Discrete levels that represent the size of the data and samples of the data at regular intervals.

What type of signal does the given graph represent?

Digital signal.

What information can be lost in a digital signal?

Why would multiple simulations of a brain's growth be useful?

It allows the user to see the effect of specific variables.

What does DISPLAY(List1[2]) output?

6.

Why might it be better to run simulations rather than conduct real-life experiments?

Simulations can be run much more quickly than real life.
