-
-Very large and expensive.
-They used vacumm tubes (glass bulb and wire)
-First computer: ENIAC -
-They used transistors. (smaller in size, became faster and cheaper)
-
-They used integrated circuits (IC) is smaller than transistors an can work as fast as thousands of them.
-This computers became faster, cheaper an smaller. -
-They used microprocessors, that consists of a small silicon chip on which thousands of circuits are placed.
-Smaller, portable and cheaper.
-Use less electricity and produce less heat. -
-Scientists are now trying to develop computers that can think on their own.
-Artificial intelligence AI.
