Binary Data

Computers can only store

• Numbers

• Text

• 0s and 1s

• RAM

Answer explanation

When you program a computer in a language like python - that gets turned into a more basic language binary which gets turned into electricity for the computer to understand

What is the name of the system that we use to represent color in pixels?

• Binary

• RGB

• Bytes

• Bits

Answer explanation

This stands for red, green, blue. The adding of these three colors can make any color!

What is a Transistor?

• The electricity Inside a Computer

• The switch inside a computer

• The storage space inside a computer

• The code inside a computer

Answer explanation

This is the most important invention in the last 100 years as it allowed us to make computers, phones, airpods, etc. Without it we would need to use expensive $600 vacuum tubes which break easily!

How many transistors are used when a single pixel of color is represented using RGB?

• 8

• 16

• 24

• 32

Answer explanation

Each pixel has three subpixels.

A red, green, and blue subpixel. Each is represented with a byte between 0000000 and 11111111. Add three bytes and we get 24 bits.

How many transistors are used when a single pixel of black & white is represented using RGB?

• 8

• 16

• 24

• 32

Answer explanation

To represent black and white we only need the colors white and black. (1111111 = black) (0000000) = white. So only one byte is needed.

Transistors use electricity to do what?

• Turn on the magnets inside the computer to operate the code

• Flip the millions/billions of tiny switches inside the computer

• Turn on the electromagnetism inside a computer to operate it

• Flip the millions/billions of electrons inside the computer

Answer explanation

Transistors act like tiny switches that store electricity in a pattern to represent things like letters, pixels, or sounds.
