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.
