Electronics History Timeline (600 BC to 2007)

Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron.

Definition of Electronics: The branch of physics that deals with the emission and effects of electrons and with the use of electronic devices. Electronics refers to the flow of charge (moving electrons) through non-metal conductors (mainly semiconductors), whereas electrical refers to the flow of charge through metal conductors.

History of electronics dates back to 600 BC.

Let us now have a look at the timeline of discoveries and inventions in the field of electronics and electrical engineering fro 600 BC to 2011.
