ICT Evolution Flashcards
this period served as the bridge between our current period and the premechanical period. It was this time that the interest in automating and speeding up numerical calculations grew.
Mechanical Period (1450-1840)
The highlight of the mechanical period is the
advent of the mechanical calculator
called _____
pascaline
who invented pascaline?
BLAISE PASCAL along with WILHELM
SCHICKARD
who was the first computer programmer
Lady Ada Augusta Byron Lovelace
what considered to be the first programmable mechanical calculator.
Analytical Engine
who invented the Analytical Engine
Charles Babbage
This period ushered the new age in communications and information. The use of electricity for information handling and transfer bloomed.
Electromechanical Period (1840-1940)
period where humans started communicating using words and pictograms carved in rocks. Then they started to write symbols as substitute for pictures to depict ideas, objects and animals which gave rise to our modern alphabet.
Premechanical Period (3000 BCE - 1450 CE)

papyrus plant
what were the first data centers in history, due to compiled records written on pieces of paper that are bounded together.
libraries
a simpler, faster, and more organized way to count
numerical system
A calculation tool performs addition and subtraction, often constructed as a wooden frame with beads sliding on wires.
abacus
the abacus was known to have existed in _____ and _____
Babylonia and China
this period concentrated primarily on the development of machines that will enhance calculation speed
mechanical period
considered the first electrical communications device and the first device to use electricity to transmit information over an electrical media.

who invented the telephone
Alexander Graham Bell in 1876
4 main events in electronic period
late vacuum tubes period,
