1 5 Generations of Computers Ms. Ceejay Jader

2 FIRST GENERATION : Vacuum Tubes a glass tube surrounding a vacuum (an area from which all gases have been removed). What makes it interesting is that when electrical contacts are put on the ends, you can get a current to flow though that vacuum. Thomas Edison noticed this first in 1883

4 ENIAC

5 Second Generation Replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 50s : Transistors

6 Third Generation Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers : Integrated Circuits

7

8 Fourth Generation Microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip 1971-Present: Microprocessors

9 NEW Motherboards

10

11 Fifth Generation Based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. Present and Beyond: Artificial Intelligence
