Electronic engineering

Electronic engineering (i′lek′trän•ik ′en•jə′nir•iŋ) is a discipline dealing with the behavior and effects of electrons (as in electron tubes and transistors) and with electronic devices, systems, or equipment. The term now also covers a large part of electrical engineering degree courses as studied at most European universities. In the U.S., however, electrical engineering implies all the wide electrical disciplines including electronics.
In many areas, electronic engineering is considered to be at the same level as electrical engineering, requiring that more general programs be called electrical and electronic engineering (many UK and Turkish universities have departments of Electronic and Electrical Engineering). Both define a broad field that encompasses many subfields including those that deal with power, instrumentation engineering, telecommunications, and semiconductor circuit design amongst many others.

Terminology
The name electrical engineering is still used to cover electronic engineering amongst some of the older (notably American) universities and graduates there are called electrical engineers. The distinction between electronic and electrical engineers is becoming more and more distinct. While electrical engineers utilize voltage and current to deliver power, electronic engineers utilize voltage and current to deliver information.

Transistors
Pronunciation:
\tran-ˈzis-tər, tran(t)-ˈsis-\
Function:
noun
Etymology:
1transfer + resistor; from its transferring an electrical signal across a resistor
Date:
1948
1 : a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (as germanium) with at least three electrodes

Electron
Pronunciation:\i-ˈlek-ˌträn\
Function:noun
Etymology:electr- + 2-on
Date:1891
A stable subatomic particle in the lepton family having a rest mass of 9.1066 × 10-28 grams and a unit negative electric charge of approximately 1.602 × 10-19 coulombs.
