#22
The test condition is invalid
A round-off error occured.
An overflow error occured.
The format is incorrect for this condition.
6
What is one way in which number systems are abstract?
They use constants
A number can be best represented by one number system
Symbols can not be used to add, subtract, multiply, or divide them
The same amount can be represented by different number representations
7
Which of the following best describes abstraction?
Simplifying complexity to make the concept more general
A set of instructions to do a task

When an integer requires more bits than possible to represent
17
Data compression algorithms are used when the data
needs to be sent a large physical distance away
needs to be kept secure
is too large to send in a timely manner
needs to be shared with a large number of people
18
Why is analyzing data with computers important?
To test due diligence
To increase the viability of server farms
