16. Worlds Smallest pc
 It’s increasingly difficult to envision a time
when a single computer weighed 30 tons,
took up as much space as a full-sized school
bus and was much slower than even a
modern pocket calculator.
 Now this... the M^3 is believed to be the
world’s smallest autonomous computer

17. Abacus
The abacus is often
wrongly attributed
to China. In fact,
the oldest surviving
abacus was used in
300 B.C. by the
Babylonians.

18. Leonardo da Vinci
Leonardo da Vinci
(1452-1519) made
drawings of gear-
driven calculating
machines but
apparently never
built any.

19. Napier’s Bones
Napier published
his version in 1617
in Radiology printed
in Edinburgh, Scotla
nd, dedicated to his
patron Alexander
Seton

20. Slide Rule
Napier's invention led
directly to the slide rule,
first built in England in
1622 and still in use in
the 1960's by the NASA
engineers of the
Mercury, Gemini, and
Apollo programs which
landed men on the moon.

21. Blaise Pascal along
with Wilhelm
Schickard was one of
two inventors of the
mechanical calculator
in the early 17th
century. Pascal
designed the machine
in 1642

Punched cards
were first used by
Basile Bouchon and
Jean-Baptiste
Falcon (fr) .

23. 23
Charles Babbage 1791-1871
Originated the
concept of the
programmable
computer, and
designed one in
1833.

24. The Analytical
Engine was a
proposed mechanical
general-purpose
computer designed by
English mathematician
Charles Babbage. It
was first described
in 1837 .

25. Hollerith Desk
Hollerith's technique
was successful and the
1890 census was
completed in only 3
years at a savings of 5
million dollars.

26. Lowa State University’s
role in the digital
computing history began
in 1937, when a physics
professor and an
electrical engineering
alumnus began working
to develop the world’s
first electronic digital
computer.

27. ABC Computer
Being completed by
1942, the Atanasoff-
Berry Computer
(ABC) was the first
electronic computer.
It was designed and
built by John Vincent
Atanasoff and his
assistant, Clifford

28. 1951 – UNIVAC
First commercial
computer Between
1951 and 1958, 47
UNIVAC I computers
were delivered.

1953 – IBM 701 EDPM Computer
IBM enters the market
with its first large
scale electronic
computer.
It was designed to be
incomparable with
IBM's existing punch
card processing system,
so that it would not cut
into IBM's existing
profit sources.

30. The Intel 8080
("eighty-eighty") was
the second 8-bit
microprocessor
designed and
manufactured by Intel
and was released in
April 1974.

The first
computer
installed in
Bangladesh in
1964

32. Our journey starts in 1940 with vacuum tube
circuitry and goes to the present day -- and
beyond -- with artificial intelligence.

58. Hardware
There has three parts such as:
1. CPU
2. Input Device
3. Output Device

59. CPU
There has RAM, ROM, Video Display, Sound Card, Network Card.

60. Input Devices
Keyboard, Mouse, Scanner, Graphics Tablets, OCR, OMR,
Video Camera, VCR are input devices.

61. Output Devices
Monitors, Printer, Plotter, Speaker, LCD Panel and
Video Projector are the example of output devices.

62. Software
There are two kind of software,
1. Application Software &
2. System Software / Operating System.

63. Application Software
There has also two parts.
1. Package Software &
2. Customized Software

64. Package Software
Microsoft Office, Firefox are the example of Package
software.

65. Customized Software
When a user customized a software to solve problem then
that is customized software.

66. Operating System
Windows, IOS, Android, Linux are illustration of Operating
system.

67. Operating System
Windows, IOS, Android, Linux are illustration of Operating system.

68. A computer has two kinds of components:
