microchips
Explanation:
The size and price of computers began to decline after the 1950s. The giant machines were not profitable because of the constant maintenance costs. The main need was to replace the electric valves with a new technology that would allow a more discreet storage and would not be so responsible for generating excessive heat, avoiding overheating. In this period, the research of the integrated circuits, the microchips, responsible for the increasing miniaturization of the electronic equipment begins.
