Pick the two statements that are true about the Internet Protocol (IP):
Each device or computer on the Internet is assigned a unique IP address.
IP is a secret protocol shared between the sender and receiver.

Which of the following would result in a better digital approximation of an analog black and white image?
Increasing the size of each sample square.
Decreasing the size of each sample square, thus increasing the number of samples taken.
Using fewer bits to represent the image.
Using decimal numbers to represent each pixel.
Assume your friend just sent you 32 bits of pixel data (just the 0s and 1s for black and white pixels) that were encoded after sampling an image. Choose the two statements that are true.
Choose Two.
The digital image would be an exact copy of the original analog image.
Using fewer bits to represent an image usually results in a sharper, more detailed image.
The 32 bits of pixel data are enough to produce a digital image, but the quality depends on how the original image was sampled.
The fact that only 32 bits were used suggests that relatively large sample squares were used, which could cause the image to lose detail.
Which statement about analog and digital images is true?
With advances in technology, digital images look exactly like the analog images they represent.
Sampling an analog image more frequently produces a digital image with a better representation.
Analog images come from data that is measure at regular intervals.

The data is transformed to always make it smaller. It cannot always be re-constructed back to the orginal.
How is a Creative Commons license different from regular copyright?
It is different in name only - in practice, it does the same thing.
IT allows other to share and reuse your work if they pay you first.
It allows your work to be shared, reused, and remixed to help spark more creativity. But only in the ways you specify.
It is the most restrictive type of copyright, not allowing anyone to use your work for any reason.

Which of the following is true of how computers represent numbers?
Using a fixed but large number of bits can eliminate the possibility of round off error when representing numbers in binary.
With a fixed number of bits some numbers are too large to represent in a computer which will lead to overflow errors.
Using a fixed but large number of bits, for example 128, eliminates the possibility of overflow errors.
