Will mainly focus on:
- Input interfaces
- CPU and Memory
- Output interfaces The sensors and actuators will be abstracted in this course.
Sensors
Inputs to the system, takes external forms of informations and turns it into an electrical form.
Actuators
Outputs of the system, takes an electrical input and does something with it (actuates a motor).
Analog vs Digital Signals
Basically continuous vs discrete values. Computers deal with digital signals.
