Here is some information about the main components of different generations of computers:
First generation (1940–1956)
Used vacuum tubes for electronic components and electrostatic tubes or mercury delay lines for storage
Second generation (1956–1963)
Used transistors for calculations, which were smaller, faster, more reliable, and consumed less power than vacuum tubes
Third generation (1964–1971)
Used integrated circuits, which increased speed and efficiency and allowed users to interact with computers through keyboards and monitors
Fourth generation (1972–2010)
Used microprocessors, which allowed computers to become smaller and more personal by packing thousands of circuits onto a single chip
Fifth generation (2010–present)
Uses artificial intelligence (AI) to make computers act more like humans, such as in voice recognition and entertainment
