THE FOURTH GENERATION, 1971-TODAY: THE MICROPROCESSOR
First microprocessor.
Invention of Intel’s 4004 microprocessor on
which numerous ICs could be built.
General- purpose processor-on-a-chip.
Extension of third generation technology.
Vast implementation- digital watches,
pocket calculators.
THE THIRD GENERATION, 1965-1970: THE INTEGRATED CIRCUIT
An IC- A complete electronic circuit on a
small chip of silicon (non-metallic substance)
A chip is much smaller in size- ½ inch square, can contain
thousands of electronic components
An IC was able to replace an entire circuit
board of transistor with one chip of silicon much smaller than a transistor.
1965- ICs began to replace transistors.
Software became more sophisticated, using
terminals to access the computer
