7. Information and Communications
Technology (ICT)
is a dynamic field and its innovations are
endless.
its applications are continuously evolving and
improving to cater and ease human activities.
Information and Communications Technology Today:
Development and Commonly Used Tools
9. refers to the technologies, both hardware and
software, that enable humans to communicate with
one another.
Common misconception: ICT is Internet or
computer alone.
ICT is any form of technology that enables you to
communicate.

10. Evolution of ICT
The beginning of ICT can be traced back when human started
to use objects to communicate with one another.
Four main periods in history that divide the era of ICT:
- premechanical
- mechanical
- electromechanical
- electronic

The devices, technologies,
and processes that humans
enjoy today are products
of centuries of
improvements and
innovations built on
foundations prepared by
the early humans.
11. around 3000 BCE to 1450 CE
humans started communicating with one another
using words and pictograms curved in rocks
started to write symbols as substitutes for pictures to
depict ideas, objects, and animals
when paper was finally produced from the papyrus plant,
storing of information was revolutionized

22. Telegraph
first device to use electricity to transmit information over an electrical media
first invented in 1837 by William Cooke and Sir Charles Wheatstone
the first working model used five magnetic needles that could be pointed
around set of letters and numbers by using electric current
in 1844, American inventor Samuel Morse successfully introduced the first
single-circuit telegraph that gave rise to Morse Code

25. humans were not satisfied with simply transmitting symbols or
letters
became fascinated with the idea of voice transmission
in 1876, Alexander Graham Bell was granted the patent for the
telephone
the telephone converts sounds into electricity and enables the
telephone network to transmit it over copper wires

29. Four main events:
transistor
- was invented in 1947
- it is an electronic device with properties and functions similar to
vacuum tubes but it is lightweight and faster
- foundation of every electronic device today
- you can find transistor for every electronic device
- full transistor computer was developed in 1957 and was faster
than vacuum computer

31. Four main events:
integrated circuit (IC)
- American engineer Jack Kilby introduced the IC
- it is a device that is composed of a group of transistors
and circuit elements compressed in a single package
- it revolutionized the use of computers and electronic
devices

32. - it is integrated in a chip or a
single package, limiting the distances
between components, resulting in a
faster operating speed
- smaller devices intended for
information processing and
communication were developed
