Modern computers divide sound waves into discrete segments called...

• amplitude

• samples

• bit depth

• waveform

Early computers used ​ (a)   , or one byte, to represent each sample. That means each sample had only ​ (b)   possible values.

• 8 bits
• 256
• 65,000
• 32 bits

• 16 bits

Sampling rate is measured in...

• hertz (Hz)

• bytes (B)

• bits per second (bps)

• pixels

When it comes to digital audio, higher sampling rates have ​better quality but require more...

• storage space

• waveforms

• bit depth

• analog output

Videos appear smoother and more fluid when playing if they have a...

• higher frame rate

• lower frame rate

• higher bit depth

• lower bit depth

What are pixels?

• Tiny dots of color

• Waves created by changes in pressure in the air

• Measurement for how much memory the computer uses to display colors

• Individual frames that make up a video

If you count how many pixels wide and tall a video frame is, you know its...

• color depth

• sampling rate

• resolution

Color depth measures how...

• much memory the computer uses to display colors

• much electricity the computer needs to display particular colors

• many pixels per inch a computer monitor has

• how many colors can be displayed in a single frame
