| Moore's Law | The observation that the number of transistors that could be packed onto a integrated circuit seemed to double ever two years or so |
| Byte | An 8-bit sequence |
| Parity bit | A bit that is added as the leftmost bit of a bit string to ensure that the number of bits that are 1 in the bit string are even or odd. |
| Even parity scheme | When the eighth bit, the parity bit, is set to 1 if the number of 1s in the 7 data bits is odd. |
| Odd parity scheme | When the eighth bit, the parity bit, is set to 1 if the number of 1s in the 7 data bits is even. |
| Variable | A symbol that represents a memory location where a piece of data can be stored. |
| Value | A symbol of a piece of data |
