Applied electronics combines the methods from physics, computing and electronics. Electronics has evolved over time from a science to a technology. As a science, Electronics revolves around the study of devices and methods to control the motion of electrons. This is because moving electrons can do work.As a technology, electronics revolves around techniques and methodologies for design and development of systems that generally enhance the human capacity in various ways. In short, science encompasses the discovery and study of devices and systems based on natural laws. Technology on the other hand is based on study and innovation of devices and systems based on utility.
The disciplines of electronics include:
Analogue electronics
Digital electronics:
Microprocessors
Power Electronics
Embedded Systems Deep Machine Learning
Many important problems are solved by bringing together all of these disciplines. A case in point is cyber-physical systems which integrates physical and cyber-space.
