Question

The "integrated circuit" has revolutionized our electronics technology because it

is a miniature circuit.

allows faster circuitry.

allows millions of individual transistors to be placed on a tiny semiconductor chip.

is/does all of these.

Answer 1

Good point by the other person posting... you won't learn anything by simply asking the questions to others.

Answer 2

all of the above.

From wikipedia

Integrated circuits were made possible by experimental discoveries which showed that semiconductor devices could perform the functions of vacuum tubes, and by mid-20th-century technology advancements in semiconductor device fabrication. The integration of large numbers of tiny transistors into a small chip was an enormous improvement over the manual assembly of circuits using discrete electronic components. The integrated circuit's mass production capability, reliability, and building-block approach to circuit design ensured the rapid adoption of standardized ICs in place of designs using discrete transistors.

There are two main advantages of ICs over discrete circuits: cost and performance. Cost is low because the chips, with all their components, are printed as a unit by photolithography and not constructed one transistor at a time. Performance is high since the components switch quickly and consume little power, because the components are small and close together. As of 2006, chip areas range from a few square mm to around 350 mm², with up to 1 million transistors per mm².

Answer 3

Have you actually attempted to study these questions at all, or were you just hoping that someone else would be nice enough to do your entire homework set for you?
