What's the word that "Binary digit" gets shortened to?
(a)
How many bits are in a byte?
1
2
4
8
Binary is a base-2 number system because there are only two digits used: 0 and 1. With one bit you can represent two different values. How any values can you represent with two bits?
2
3
4
8
In fact, there's a pattern for how many values you can represent with a certain number of bits. If you take 2 and raise it to the power of the number of bits, you get the number of values. Two bits can represent four values because 22= 4. Three bits can represent 23= 8 values. How many values can you represent with six bits? You can write your answer as a number (like 16) or as a number with an exponent (written like 4^2).
(a)
Each time you add an additional bit, what happens to the number of values that you can represent?
It increases by 1
It doubles
It quadruples
It gets multiplied by 10
When we count in binary, we start counting at zero, which is represented by 0000. Which of the following is also a way to represent zero?
0
01
10000
000.1
What is the highest number you can count to using only three bits? (your answer should be a single number)
(a)
In the decimal system, the place values (starting from the right) go: 1, 10, 100, 1000, and so on. In binary, how do the place values (starting from the right) go?
0, 2, 4, 8, etc.
1, 2, 4, 8, etc.
0, 1, 2, 4, etc.
1, 4, 16, 32, etc.
The four-bit binary number for 1 is 0001. What is the four-bit binary number for 6?
(a)
What is the decimal number represented by the binary number 1111?
(a)

They show one color in an image
They can only show black and white colors
Pixel values can be stored with binary
What three letters represent the three color channels used to store the value for color pixels? (your response should be three letters long)
(a)
