Generation

The first generation of the computer was vacuum tubes.The first computers used vacuum tubes for circuitry and magnetic drums for memory.The vacuum tubes were very big and took up most of the room.

The second generation

Generation

The second generation is transistors.Transistors replaced vacuum tubes and ushered in the second generation of computers.The transistor was invented in 1947.

The third generation

Generation

The third generation was integrated circuits.The development of the integrated circuits was the hallmark of the third generation of computers.

The fourth generation

Generation

The fourth generation of computers was microprocessors.The microprocessors brought the fourth generation of computers,as thousands of integrated circuits were built onto a single silicon chip.

The fifth generation

Generation

The fifth generation of computers was artificial intelligence.Fifth generation computing devices,based on artificial intelligence,are still in development,though there are some applications,such as voice recognition,that are being used today.
