1. COMPUTER’S HISTORY About Computer’s history, we can to say that we have five gerations. First Generation.- Thermionic vacuum tubes. Mid-1940s. IBM pioneered the arrangement of vacuum tubes in pluggable modules. IBM 650 was a first-generation computer. Second Generation.- Transistors 1956. The era of miniaturization begins. Transistors are much smaller than vacuum tubes, draw less power and generate less heat. IBM 7090 was a second-generation computer. Thrid Generation.- Integrated Circuits (silicon chips containing multiple transistors)1964. The chips could be packed together onto a circuit board to achive unheard-of logic densities. The IBM 360/91 was a hybrid-second and thrid-generation computer. Fourth Generation.- It started with the invention of microprocessor. The microprocessor contains thousands of ICs. Thed Hoff produced the first microprocessor in 1971 for INTEL. Fifth Generation.- Fifth generation computing intelligence are still in development though. There are some applications, such as voice recognition that are being used today.
