Our world is analog but computer's world is digital
analog refers to a continuously changing representation of a continuously variable quantity
digital refers to representing these variable quantities in terms of actual numbers, or digits
So we have to do something for computers to understand our world, there will be discuss in ADC & DAC part
Embedded system is computer system with a dedicated function embedded as a part of a complete device and have limited resources as memory, peripheral, speed, ...
They have some features as: small size, low per-unit cost, low power consumption, ...
This part will be added later
Sensors are devices that measure physical quantities
sensor can be seem as input of a system, it responsible to "read from physical world"
Actuators are devices that modify physical quantities
actuator can be seem as output of a system, it responsible to "write to physical world"
