**Basics:**

- It is a series of ONs and OFFs:
- This is what makes electrical gadgets function.
- Digital electronics only has these two states.

- Bases:
- A thousand is ten to the base 3:
- 10^3.

- A hundred is ten to the base 2:
- 10^2.

- Ten is ten to the base 1.
- One is ten to the base 0.

- A thousand is ten to the base 3:

**Base 2:**

- Each successive base is equal to 2^(n-1):
- n being the digit number counted from the right:
- Say for instance the binary number 10:
- Since the 1 is the second digit, 0 being the first, from the right.
- 10 = 21 = 2.

- Say for instance the binary number 10:

- n being the digit number counted from the right:

**Bits and Bytes:**

- When a flow of electricity is high we call it a 1 and when said flow is low we call it a 0.
- Each 0 or 1 is a bit.
- There are 8 bits in a byte.

- Bits have only 2 possible digits, decimal has 10:
- This is why it is so much easier to implement base 2.
