♥●•٠•..Fourth Generation Computer (1974-Present) ::VLSI / ULSI ♥ ♥ ♥

VLSI - (Very Large-Scale Integrated)
ULSI - (Ultra Large-Scale Integrated)

@ This fourth computer generation is a combination of millions transistors
@ By the 1980's, very large scale integration (VLSI) squeezed hundreds of thousands of components onto a chip.
@  The ability to fit so much onto an area about half the size of a U.S. dime helped diminish the size and price of computers.
@ Then, the single-chip processor and the single-board computer emerged.

PERSONAL COMPUTER (PC)

=) This kind of computer was introduced in 1981.
=) It used in the home, office, and schools.
=) The number of this PC in used more than doubled from 2 million in 1981 to 5.5 million in 1982.

As computers became more widespread in the workplace, new ways to harness their potential developed.  As smaller computers became more powerful, they could be linked together, or networked, to share memory space, software, information and communicate with each other.
