(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.
Second Generation
The Transistor Age

(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.
Third Generation
The Integrated Circuit Age
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.
Fourth Generation
The Microprocessor Age

(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.

In 1984, Apple
introduces the
Macintosh Computer,
with a unique, easy-touse graphical user
interface.
In 1990, Microsoft
releases Windows 3.0,
with an enhanced
graphical user interface
and the ability to run
multiple application.
Fifth Generation

Most connected generation.
Advanced to Internet and
World Wide Web.
In 1993, Introduction of the
Mosaic Graphical Web
Browser, which led to
organization of Netscape.

In 1995, Microsoft
releases Windows 95, a
major upgrade to its
Windows Operating
System.
In 1997, The number of
Internet and World
Wide Web users
estimated at 50 million.
Closing Statement

The possibilities are endless where we
can go with computers; I’m just glad I
will get to witness new generations of
the computer evolution.
