CALCULATOR IN 1642 CALLED
“PASCALINE” MADE UP OF
CLOCK AND GEARS AND
LEVERS, AND COULD SOLVE
BASIC MATH PROBLEMS

12. GOTTFRIED LEIBNITZ

14. JOSEPH MARIE
JACQUARD
-Developed an automatic
loom, in 19th century, that
was controlled by punched
card.

16. ARITHMOMETER (1820)
Invented by Charles Xavier
de Colmar, a pin-wheel type
adding machines.

18. ANALYTICAL ENGINE (1837)
THE MECHANICAL
CALCULATOR THAT TOOK
INFORMATION FROM A
PUNCHED CARDS TO SOLVE
AND PRINT MATHEMATICAL
OPERATIONS.

20. ELECTROMECHANICAL
AGE
18TH
-19TH
CENTURY

21. ELECTROMECHANICAL AGE
The discovery of ways to harness
electricity was the key advance
made during this period.
Knowledge and information could
now be converted into electrical
impulses.

22. The Beginning of
TelecommunicaTion

23. Alessandro Volta
-Invented the VOLTAIC
PILE which is considered
to be the first source of
stored electricity in the 8th
Century.

25. Telegraph
Samuel F.J. Morse invented the
first magnetic telegraph in the
year 1832 and made an
experiment version in 1815.

27. Telephone
The first successful bi-directional
transmission of clear speech by
Bell and Watson was made on 10
March 1876 when Bell spoke into
his device, “Mr. Watson, come
here, I want to see you.”

29. Marchese Guglielmo Marconi,
known for his development of a
radiotelegraph system, now
called radio in 1873.
RADIO

31. Electromechanical Computing
Pehr and Advard Scheutz
(1853) complete their tabulating
Machine, capable of processing
fifteen-digit numbers, printing
out results and rounding off to
eight digits.

33. Dorr Felt
Comptometer (1885) is a type of
mechanical (or electro-mechanical)
adding machine.
COMPTOGRAPH- Comptometer
with built-in printer.

35. Punched Cards
A punch card or punched card (or
punch card or Hollerith card or IBM
card), is a piece of stiff paper that
contains digital information represented
by the presence or absence of holes in
predefined positions.
It was used through the 20th century in
unit record machines for input,
processing, and data storage.

37. International Business Machines (IBM)
Founded in 1896 as the Tabulating
Machine Company by Herman Hollerith,
It was incorporated as Computing
Tabulating Recording Corporation (CTR)
on June 16, 1911.

function calculator
invented by Otto
Shweiger,
