Etymology
Origin of electronics
First recorded in 1905–10; see origin at electronic, -ics
Explanation
Devices that use electricity and electrical components to perform a task — like stereos, TVs, computers, and calculators — are electronics. Unless you live off the grid in a remote place, winding the watch on your wrist and cooking freshly caught fish on your campfire, your life is full of electronics. Kitchen appliances, computers, and televisions are all electronics. You can also use this word for the science of designing circuits using electrical components, or the study of the way electrons behave under various circumstances.
