Electronics Engineering
What's electronics? Electron is just a particle that can't be defined, but it has charge & tendency to flow. This nature of electron has made a separate section of study called electronics engineering .
What's electronics? Electronics is about study, designing & implementation of different components/circuits for various human necessities.
What's the difference between electronics & electrical? Semi-conductor materials/things/components differentiate electronics from electrical. Whatever the appliances a human(he/she) use each & every day, they may have fundamental dependency on electrical (A.C 230-250V, 50-60HZ), but the processing is made with the help of semiconductor components and this makes it as an electronic product.
Electronics Say, a Cell phone. A cell phone & its charger are electronic products. A domestic motor is completely electrical as it completely involves winding (conduction/induction & A.C supply).
Classification Based on the conductive properties of various elements, they are classified as conductors, semi-conductors & insulators. A combination of elements with certain characteristics, be it a conductor or semi or insulator, various electronic components are designed, termed, standardized & used.
How electronics is analogous to a living being? An Electronic product/appliance is a body in which blood called current flows through veins (Wires/Bus) Body - Product/Appliance Blood Current Veins Wires/Paths/Tracks/Bus

Purpose of Electronics Engineering The very purpose of electronics engineering is to make zillions & zillions of electrons flow through various circuits as needed for certain things being used or about to be used by humans.
