## [1] Introduction
- Turing model (mathematical model of computation)
- Data Processor (just like a function), Programmable Data Processor (have instruction or program)
- The universal turing machine (capable of computing anything that is computable.)
- The Von Neumann Model
  - concept: program state stored in memory, program stored as binary patterns
  - 4 subsystems: Memory, Arithmatic logic unit, control unit, I/O
