Question

In the late 1950s the ________ was introduced and enabled engineers to create complicated circuits in a much smaller package.

Answer 1

The answer is integrated circuits. It was envisioned in the late 1950's when engineers appreciated you could make computing components smaller by engraving transistors, resistors and capacitors into a solid block of silicon more willingly than stringing them together with wires. And as a result the modern microchip was born.
