COMPUTERS….
• Have you ever thought how computers
were first made or who made them and
how? Well ,I have and we have all
learned about it in computers 1 and 2
and it was quite cool. Do you know how
your computer is made? Do you know
who made it?

EARLY COMPUTATIONAL
DEVICES
• First calculating tool
was the abacus.
• Herman Hollerith
developed a
mechanical tabulator
based on punched
cards.
EARLY COMPUTERS
• Eckert and Mauchly both developed the first
general purpose computer ENIAC and first
commercial computer UNIVAC.

• EDSAC and EDVAC are a couple of the
earliest computers developed.
GENERATIONS AND MAIN
COMPONENTS
• First generation was made up of vacuum
tubes in 1946-1958. UNIVAC and
ENIAC.
• Second generation computers were
made up of transistors in 1956-1963.
• Third generation computers were made
up of integrated circuits in 1965-1970.
Can carry out instructions in billionths
of a second.
GENERATIONS AND MAIN
COMPONENTS CONT.
• Fourth generation computers were
microprocessors made in 1971-today.
Altair 8800 was the first
microprocessor kit bought.
• Fifth generation computers are
artificial intelligence. Made todayfuture. Quantum and Molecular will
change in computers in years.
• Generations of Computers flyer.
INVENTORS/DEVELOPERS
• Steven Jobs and Steven Wozniak both helped
create Apple.
• Bill Gates and Paul Allen helped design
Microsoft.
• In 1991, Tim Berners-Lee developed the
World Wide Web.
INVENTORS/DEVELOPERS
CONT.

and running and
developed by
Department of
Defense.

browser made was
Mosaic which was
developed by Marc
Andreesen.
WRAP UP!
• Well have you learned anything new about
your computer? I have. Pretty fascinating how
quickly our society has become more
technological. Newer world means newer
discoveries I guess. Can’t wait to see what our
world will come up with next.
