Important Facts
(1951-1957). In 1951, Dr. John. W.
Maunchly and J. Presper Eckert Jr. introduce the first electronic digital computer—the Univac.
The Univac was actually built with Vacuum Tubes.
Between 1951-1953 IBM sold over 1,000 Computers.

Important Facts
(1958-1963). Computers in this generation
were built with transistors—small devices that transfer electronic signals across a resistor.
In 1959, General Electric Corporation introduced ERMA—the first technology that can read special characters, such as digitized information.
In 1962, Steve Russell & MIT create the first Computer Game ever.

Important Facts
(1964-1969). Manufactures began
replacing transistors with integrated circuits.
Computers with integrated circuits were much more reliable than computers with transistors.
In 1965, Digital Equipment Corporation (DEC) introduces the first Minicomputer.
In 1969, The introduction ARPANET and the beginning of the Internet.

Important Facts
(1970- 1990). Most significant advance was
the Intel 4004 Microprocessor—a specialized chip developed for Computer memory and logic.
The Microprocessor revolutionized the Computer Industry.
In 1981, the introduction of the IBM PC, which contained an Intel Microprocessor Chip and Microsoft’s MS-DOS operating system.
