, ARTIFICIAL INTELLIGENCE
AI is a broad area of computer science that makes machines seem like they have human
intelligence. For example, it is not only when a computer is programmed to drive a car
by obeying traffic signals, but it is when that programme also learns to exhibit signs of
human like a road rage. The term AI was coined back in 1956 by Professor John
McCarthy. He tried to prove that machines could learn like a young child using trial and
error

example, e-mail, phone calls, text messiging, viewing pages on the Internet,

electromagnetic waves. Examples of telecommunications systems: telephone newtork,
the radio broadcasting system, computer networks and the Internet. The nodes in the

technologies that we are used today are the result of evolution
In ancient times, people utilized fire, smoke and flags to communicate at a
distance. Messengers relied on horses to deliver written documents
More electrical devices such as telegraph, telephone and radio were
invented when electricity was discover in China
Telecommunications innovations continued envolving in the tweentieth
century. There was television, analog computers, digital computers,
Internet and more
Modern society is an information society because it is built by advanced
communication technologies
In 1969 a four-node network emerged between some universities located in the USA.
This network would become ARPANET. At the beginning it was restricted to non
comercial uses and eventually it combine with other networks to form the Internet
To conclude, people not only interact with each other but also with media machines.
Nowadays, new technologies are constantly comming out introducing inovations that
