# 01 - Introduction to Boolean Logic

1. Logic is the foundation on which a computer system is built internally. Bits are switched __________________ using the binary 1's and 0's. In Boolean Logic, these translate into T (true) and F (false) statements.
`Boolean Logic is considered the very basis of computing. `

on and off

up and down

forward and backward

2. George Boole was a largely self-taught English mathematician, philosopher and logician and is best known as the ______________

creator of the Boolean Von Neumann circuit used in modern CPUs

philosopher that asked questions about the nature of the universe and relativity

author of The Laws of Thought (1854) which contains Boolean algebra

founder of the Binary (two digit) language

3. The keyword Bool represents a Boolean datatype in many programming languages and is named after George Boole.
`Note: Boolean variables can be either 'True'(1) or 'False'(0)`

FALSE

TRUE

5. In Boolean Logic you start off with the idea that some statement P is either________________________, it can’t be anything in between (this called the law of the excluded middle

True or False

Excluded or Included

Data based on non-data based

Metallic or Non Metallic

6. The fundamental operators in Boolean logic are the operators And, Or and Not. (there are others too)

FALSE

TRUE

7. For example, if P is true then Not(P) is false which is like saying:

if “today is Monday” is true then “Not(today is Monday)” is false.

if "today is Monday" is true then "Not(today is Monday)" is also true

if "today is Monday" is false then "Not(today is Monday)" is also false

if "today is Monday" is false then "Not(today is Monday)" could be either true or false

8. Boolean logic reflects the binary logic of logic gates and transistors in a computer's CPU. (The video below provides a nice intro)
`The early designers of computers quickly realised that logic can be used within a computer to work out problems. (because computer data is either 1(True) or 0(False)`

FALSE

TRUE

9. One of the most recent uses of Boolean logic is in search engines

TRUE

FALSE

10. To understand how boolean logic works in practice, you need to know and understand the working of the different……
