1 COMPUTER HISTORY AND ITS GENERATIONS.
:
·
FIRST GENERATION
(1940-1956)
Ø Use
vacuum tubes
Ø for
circuitry and magnetic drums for memory, and were often enormous, taking up
entire rooms.
·
SECOND
GENERATIONS(1956-1963)
Ø Transistors
replaced vacuum tubes and ushered in the second generation of computers.
Ø The
transistor was far superior to the vacuum tube, allowing computers to become
smaller, faster, cheaper, more energy-efficient and more reliable than their
first-generation predecessors.
·
THIRD GENERATION (1964-1971)
Ø integrated
circuit was the hallmark of the third generation of computers. Transistors were
miniaturized and placed on silicon chips, called semiconductors, which
drastically increased the speed and efficiency of computers.
·
FORTH GENERATION (1971-Present)
Ø The
microprocessor brought the fourth generation of computers, as thousands of
integrated circuits were built onto a single silicon chip.
·
FIFTH GENERATION
(Present and Beyond)
Ø Fifth
generation computing devices, based on artificial intelligence, are still in
development, though there are some applications, such as voice recognition,
that are being used today.
