☀️An integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, usually silicon. ☀️Large numbers of tiny MOSFETs integrate into a small chip. ☀️First generation (1940 - 1956) vacuum tubes as a major piece of technology. ☀️The ENIAC is example of 1st generation computer. ☀️Second generation (1956 - 1963) use of transistors. ☀️Third generation (1964 - 1971) use of Integrated circuits. ☀️Fourth generation (1972 - 2010) use of the microprocessor ☀️Fifth generation (2010 to present) use Artificial intelligence
