Human-machine analogy
The machine system operates very much similar to the human body. The working cycle of a machine contains mainly three things
Input
Processing
Output
Similarly, these three terms are very much important for humans to understand the situation.Microcontrollers and microprocessors
Both microcontrollers and microprocessors are integrated circuits with a difference in the arrangement of external peripheral. the microprocessor has CPU inside them whereas the microcontroller has a fixed amount of RAM, ROM, EEPROM available with CPU.
