The role of a microprocessor is to only do processing whereas a microcontroller handles processing as well as a particular application.

Realtime systems

These are systems which must operate within a specified time constraint, never missing the deadline. For example a flight control system needs to work in real time and not display outdated information to prevent accidents and incorrect readings.

Control system

A control system manages, commands and directs the behaviour of other devices/systems. It makes use of control loops to do this

Intelligent tutoring system
