Question

What present-day device did the invention of the transistor most directly influence?

Answer 1

D. Laptop computer is the present-day device that has a transistor because
Automobiles and the atomic bomb definitely do not have transistors.
The light bulb has a resistor, not a transistor, although they rhyme perfectly.
A transistor can be defined as, from a Google search, "a semiconductor device with three connections, capable of amplification in addition to rectification."

Answer 2

The correct option is D

The transistor is a semiconductor electronic device used to deliver an output signal in response to an input signal. It fulfills functions of amplifier, oscillator, switch or rectifier. Currently it is found in virtually all electronic devices for daily use such as radios, televisions, audio and video players, quartz watches, computers, fluorescent lamps, tomographs, cell phones, although almost always within the so-called integrated circuits.

The other objects named do not have transistors.
