von Neumann
instructions exist within memory, which are fetched, decoded, and executed by the processor before cycling back to fetch the next one

Data Representation
Binary is representation of data in bits of two states, "0" and "1"
Each bit stores an integer value (powers of 2), standard byte contains 8 bits.
Example: 0101 is 5, as the "1"s are lit in the "4" and "1" slot (4+1 = 5)
Logic gates are an adaptation of Boolean algebra used to determine results given certain logical processes
