How many different values can a binary number with 4 bits store, Ari?
How many different values can a binary number with 8 bits store, Bo?
How many different values can a binary number with 10 bits store, Esme?
4.
In the signal strip, how many bits does each sample use, Jun?
- 2
- 3
- 8
5.
In the signal strip, what value does the bit pattern 111 stand for, Kira?
Use the picture in question 4.
- 111
- 3
- 7
6.
In the signal strip, the wave is sampled more often. What improves, Luz?
Use the picture in question 4.
- The sound wave gets louder
- The copy follows the wave more closely
- Each sample gets more bits on its own
7.
How many bits are in one byte, Milo?
- 8
- 2
- 10
8.
What values can a single bit have, Noah?
- 1 to 10
- Any whole number
- 0 or 1
9.
A little noise is added to a digital signal. Why can it still be read, Tala?
- Noise turns into extra music
- Small noise doesn't flip 0s and 1s
- Digital signals can't pick up noise
10.
What is one risk of keeping photos digitally, Zee?
- They can be lost if a drive fails
- They fade in sunlight like old prints
- They get heavier as you add more

Digital information: bits, sampling and storage. Every version has 10 questions, and the answer key prints on the second page.

I can say that n bits give 2ⁿ values and 8 bits make a byte.
I can tell SI prefixes (1 MB = 10⁶ bytes) from binary prefixes (1 MiB = 2²⁰ bytes) and convert TB to GiB.
I can find a sound file's size from sample rate, bits per sample, channels and time, and say why a recording needs over twice its highest frequency.
I can explain why digital copies resist noise and are easy to store, and the risks: loss and theft.

Standard: HS-PS4-2

bit: A single 0 or 1

byte: 8 bits

sampling rate: How many times a second a signal is measured

SI prefix: A power of 10, such as kilo = 1000

binary prefix: A power of 2, such as kibi = 1024

Your child doubled the number of bits. Each extra bit doubles the count of values, so n bits give 2ⁿ.

Your child gave the size in bits. Divide by 8 to get bytes before converting to MB.

Your child treated a GiB like a GB. A GiB is 2³⁰ bytes, about 7% more than 10⁹, so fewer fit.

What is the most common mistake with digital information: bits, sampling and storage?

Your child doubled the number of bits. Each extra bit doubles the count of values, so n bits give 2ⁿ.
