This document summarizes the five generations of computers from 1940 to present. The first generation used vacuum tubes and magnetic drums. The second generation used transistors instead of vacuum tubes. The third generation used integrated circuits on silicon chips. The fourth generation had microprocessors that placed all components on a single chip. The fifth generation focuses on artificial intelligence through parallel processing and superconductors.

The Generations
of Computers

5. The Generations of Computers
● The computer has evolved from a large-sized simple calculating
machine to smaller but much more powerful machine.
● The evolution of computer to the current generation is termed as the
generations of computers.
● Each generation of computer is designed bases on a new technological
development, resulting in better, cheaper and smaller computers that
more powerful, efficient and faster than their old ones.
● Currently there are five generations of computer.

First Generations
of Computers

7. First Generation of Computers
(1940-1950)
● The first computers used vacuum tubes (a sealed glass tube
containing a near-vacuum while allows the free passage of electricity)
for circuitry and magnetic drums for memory.
● They were often enormous and takes up a lot of space.
● First generation of computers relied on machine language.
● They were very expensive to operate and in addition to using a great
deal of electricity, generated a lot of heat, which was often the cause of
malfunctions (defect or breakdown).
● Examples of First Generation of computers are UNIVAC and ENIAC.

UNIVAC ENIAC

Secound
Generations of
Computers

10. Second Generation of Computers
(1950-1960)
● Transistors replaced vacuum tubes and ushered in the second
generation of computers.
● Second-generation computers moved from cryptic binary machine
language to symbolic.
● High-level programming languages were also being developed at this
time, such as early versions of COBL and FORTAN (second generation
languages).
● These were also the first computers that sored their instructions in their
memory.

11. Examples of Second Generation Computers
ENIAC
IBM 1244

Third Generations
of Computers

13. Third Generation of Computers
(1950-1960)
● The development of the integrated circuit was the hallmark of the third
third generation of computers.
● Transistors were miniaturized and placed on silicon chips, called
semiconductors.
● Instead of punched cards and printouts, users interacted with third
generation of computers through keyboards and monitors and interfaced
interfaced with an operating system.
● Allowed the device to run many different applications at one time.

14. Examples of Third Generation Computers
CDC 1604 PDP(PersonalData Processor)

Fourth
Generations of
Computers

16. Fourth Generation of Computers
(1960-1970)
● The microprocessor brought the fourth generation of computers, as
thousands of integrated circuits were built into a single silicon chip.
● The intel 4004 chip, developed in 1969, located all the components of the
computer.
● From the central processing unit (CPU) and memory to input/output controls
on a single chip.
● Fourth generation of computers also saw the developments of GUI’s, the
mouse and handheld devices.

17. Examples of Fourth Generation Computers
IBM 4341 ENIAC

18. 05
Fifth Generations
of Computers

19. Fourth Generation of Computers
(1970-present)
● Fifth generation computing devices, bases on artificial intelligence.
● Are still in development, though there are some applications, such as voice
recognition.
● The use of parallel processing and superconductors is helping to make
artificial intelligence a reality.
● The goal of fifth-generation computing is to develop devices that respond to
natural language input and are capable of learning and self-organization.

20. Examples of Fifth Generation Computers
Laptop Mobiles

21. What’s next for the Generation of Computers
● Next generation computing industry device is fundamentally different
than conventional & supercomputers. It is also called high
performance computing and uses technology based on quantum
phenomena. Unlike classical computers, it uses quantum bits to
process the data.
