9. ICT
Technology required for information processing, particularly
the use of electronic computers, communication devices and
software applications to convert,store,protect,process,transmit
and retrieve information
 INFORMATION- knowledge obtained from reading,investigation,study
and research.
Tools to transmit info:
 Telephone
 Television
 Radio
 COMMUNICATION- act of transmitting,verbal or non-verbal
 TECHNOLOGY- scientific knowledge,experience and
resources,vital/tool in communication

10. THE EVOLUTION OF COMPUTER
COMPUTER
 Automatic,electronic,data processing system
 Accepts data performs operations on data presents data and stores output as needed
process
User
Raw data Info.

11. COMPUTER CHANGE OVERTIME
 ABACUS- invented in
1200 C.E. by
Chinese,add and
subtract and binary
counting.
 NAPIER BONES-1617-
John Napier,multiply
and add

12.  PASCALINE-1642-Blaise Pascal,operated
wheels,add and substract,also known as
arithmetic machine.
 LEIBNIZ CALCULATOR-1694-Gottfried Leibniz,use
wheelsadd,substract,divide and multiply,also
called step reckoner.

13.  PUNCHED CARD-1801-Joseph Jacquard
-give instructions to computer

14.  DIFFERENCE ENGINE AND
ANALYTICAL ENGINE
 DE-automatic mechanical
calculator designed to tabulate
polynomial functions. It was
designed in the 1820s, and was
first created by Charles
Babbage.

15.  AE- a proposed mechanical
general-purpose computer
designed by English
mathematician and computer
pioneer Charles Babbage. It was
first described in 1837 as the
successor to Babbage's
difference engine, which was a
design for a simpler mechanical
calculator.

16. PUNCHED CARD
STORAGE DEVICE-1891-
Dr. Herman
Hollerith,also called
tabulating machine,
helps sort and store
data

17.  1ST GEN COMPUTER-1942-
1956,used vacuum
tubes,big,expensive and
consumed a lot of electricity
Ex. UNIVAC-designed for
business by J. Presper Eckert and
John Mauchly
ENIAC-first
programmable and able to solve
large numerical problems-1945-
introduced Feb. 15,1946

18.  2ND GEN COMPUTER-
1956-1964-used
transistors and were
smaller,faster and
cheaper,less electricity
 3RD GEN COMPUTER-
1964-1972-they used I.Cs
and
faster,cheaper,smaller
and reliable than the 1st
and 2nd.

19. 4TH GEN COMPUTER-intel
Pentium 4-1972
onward,microprocessor,smaller,por
table,reliable,cheaper and high
storage
5TH GEN COMPUTER-(robot)-
undergoing development,recognize
image,forecast weather
1st - 5th
Efficient and convenient,vacuum
tubes replaced by transistors,Ics and
microprocessors
