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.
