• 4 Main Tasks of Computers

• the smallest piece of information; a single value storing a 0 or 1

• Bit

• Input, Processing, Storage, Output

The CPU is the brain of the computer

• True

• False

Computers use __________ to transform the 1s and 0s from input wires.

Match the following

• AND Gate

• accepts two inputs, and as long as either of those inputs is a 111, it outputs a 11

• OR Gate

• Accepts two inputs, and if both wires are '1', it outputs '1'. If either wire inputs '0', then it outputs '0'.

• Boolean Operation

• an operation that takes values that are either "true" or "false", and then outputs "true" or "false" based on a logical manipulation of those inputs

• NOT Gate

• Also known as an inverter; it accepts a single input and outputs the opposite value.
