FIRST GENERATION COMPUTERS
Used Vacuum Tubes and Magnetic Drums
for data storage.
Programs were specifically built to help the
computers do the task for which they were
manufactured.
Machine language was the only language 1st
generation computer “understood” or
accepted, making them difficult to program.

THE EDVAC
Also known as Electronic Discrete
Variable Automatic Computer
(EDVAC).
Designed in 1945 by John Von
Neumann.
This computer had a memory that
could hold both data & a stored
program.
34. THE UNIVAC 1
THE UNIVAC 1
Also known as Universal Automatic
Computer 1(UNIVAC 1).
Built in 1951 by Remington Rand.
This was the first commercial
computer to feature a magnetic tape
storage system.
36. THE SAGE
THE SAGE
Also known as Semi-Automatic Ground
Environment(SAGE).
Established in 1954.
This automated aircraft-warning
system was the largest vacuum tube
computer system ever built.
38. THE SECOND GENERATION
THE SECOND GENERATION
COMPUTERS
COMPUTERS
Was the start of the high-level
programming languages usage.
The start of the making of the first
transistor.
The birth of the two supercomputers
from IBM.
40. THE TRANSISTOR
THE TRANSISTOR
It is a device designed to act as both
a transmitter and a resistor.
The term Transistor comes from
transmitter and resistor.
Replaced the bulky & unreliable
vacuum tubes.
Making computers less power and
space.
45. PROGRAMMING LANGUAGES
PROGRAMMING LANGUAGES
Replace long, difficult machine
language with words, sentences and
mathematical formulas.
Making easier to program a
computer.
Computers are becoming more
accessible to government,
universities and businesses.
52. THIRD GENERATION
THIRD GENERATION
COMPUTERS
COMPUTERS
The invention of the integrated
circuit and semiconductor.
The birth of the first successful
minicomputer.
UNIX operating system was born.
The first GUI computer was design.
54. INTEGRATED CIRCUIT
INTEGRATED CIRCUIT
Developed by Jack Kilby of Texas
Instruments.
Combined many transistors and
other electrical components into a
small silicon chip.
This makes the sizes of the
computers smaller.
57. THE PDP-8
THE PDP-8
Developed in 1965.
The first computer to use integrated
circuits.
The first commercial successful
minicomputer because of its
reasonable cost, speed and small
size.
59. UNIX OPERATING SYSTEM
UNIX OPERATING SYSTEM
Developed in 1969 by Kenneth
Thompson and Dennis Ritchie of the
AT&T Bell Laboratories.
Capable of performing multiple task.
It was written in the C programming
language.
61. THE XEROX STAR

Also know as Intel 4004.
Can perform many input and output
operations.
Capable of reading and responding to
instructions stored on its memory.

THE ALTAIR 8800
Often called the first personal
computer.
Developed by Micro Instrumentation
Telemetry Systems (MITS).
The BASIC (Beginner’s All-purpose

Appealing to consumers because of
its software and well-written
manuals.
It can also be plugged into a standard
household outlet.
72. WINDOWS OPERATING SYSTEM
WINDOWS OPERATING SYSTEM

Microsoft continued to improve its
operating system.
Microsoft soon became the
dominating software company for
PC’s.
76. FIFTH GENERATION
FIFTH GENERATION
COMPUTERS
COMPUTERS
In 1965, Gordon Moore predicted that the
number of transistors on a silicon chip would
double every year.
This prediction was known as Moore’s Law and
indeed it is proven to be true.
Computer scientist are now working on fifth
generation computers.
This are envisioned to possess artificial
intelligence, talk with human beings in ordinary
languages, reason logically and learn from their
own experiences.
78. BALLISTIC DEFLECTION
BALLISTIC DEFLECTION
TRANSISTORS (BDTs)
TRANSISTORS (BDTs)
Currently in the experimental stage of
development.
These may replace regular transistors in
the near future.
BDTs have the potential to increase the
speed of today’s microprocessors by ten
million times.
This means that computers of the future
are likely to become extremely powerful!
80. VIRTUAL REALITY (VR)
VIRTUAL REALITY (VR)
This type of technology allows users
to use all of their senses when
interacting with a computer.
The user feel as if he or she is
completely surrounded by an
artificial environment and he or she
can manipulate the objects in the
virtual world just like real objects.
82. ARTIFICIAL INTELLIGENCE (AI)
ARTIFICIAL INTELLIGENCE (AI)
This refers to making machines exhibit
human behavior and intelligence.
Scientist are still trying to make robots
that can speak and display common sense,
emotions and consciousness like human
beings.
AI robots are expected to be capable of
adapting the behaviors to surroundings
and to the demands of a certain situation.
