According to the video, all computers do these same four things...

• Input, output, CPU, and RAM

• Crash, burn, hang, and virus

• Input, store, randomize, and print information

• Input, store, process, and output information

According to the video, INPUT DEVICES do what?

• Calculates information

• Convert physical input to binary information

• Store information

• Converts information to physical output

According to the video, MEMORY does what?

• Calculates information

• Convert physical input to binary information

• Stores information

• Converts information to physical output

According to the video, the CPU (central processing unit) does what?

• Calculates information

• Convert physical input to binary information

• Stores information

• Converts information to physical output

According to the video, OUTPUT does what?

• Calculates information

• Convert physical input to binary information

• Stores information

• Converts information to physical output

Select all of the things that are INPUT devices of your computer.

• Mouse

• Printer

• Keyboard

• Monitor

• Your cat

When we talk about BINARY in computers, we are talking about what?

• Binoculars

• Ones and zeroes

• Base-16 numbers

• Two canaries

When you type a letter on the keyboard, how is that letter sent to the CPU?

• As a series of dots and dashes

• The keyboard draws the letter on the CPU's whiteboard

• As ones and zeroes (binary)

• Different colors for different letters

According to the video, when the CPU understands that you typed the letter 'B', it does what?

• Retrieves from memory the instructions on how to draw the letter 'B', pixel by pixel.

• The CPU asks the keyboard to repeat, just to make sure there's been no misunderstanding.

• The CPU waits to see if you will press 'B' again.

• Re-converts the binary version of 'B' back to the physical, and pushes the key back up.
