Artificial Intelligence is a way of
making a computer, a computer-controlled robot, or a software think
intelligently, in the similar manner the intelligent humans think.

John McCarthy is called the Father of
Artificial Intelligence and as per him Artificial Intelligence is

“The science and engineering of making
intelligent machines, especially intelligent computer programs”.

History of AI

The History of AI began in
4th century B.C. whenAristotleinventedsyllogistic logic, the first formal deductive reasoning system.
Later in 13th centuryTalking
Headswere said to have been
created byRoger BaconandAlbertin the same periodRamon Lullinvented machines for discoveringnon-mathematicaltruths throughcombinatoricsand in 1206 A.D. an Arab inventorAl-Jazaridesigned what is believed to be the first
programmable humanoid robot, a boat carrying four mechanical musicians powered
by water flow.

15th and 16th Century

In 1456 Gutenberg Bible was
printed by Johannes Gutenberg using moveable type

Clocks, the first modern
measuring machines, were produced using lathes

Clockmakers extended their
craft to creating mechanical animals and other novelties. For example, see
DaVinci’s walking lion (1515)

17th and 18th Century

Pascal created the first
mechanical digital calculating machine

In between 1662-1666
Arithmetical Machines devised by Sir Samuel Morland were introduced

In 18th Century
large quantity of Mechanical toys like mechanical duck of Vaucanson and von
Kempelen’s phony mechanical chess player were introduced

19 Century

The first programmable machine
with instruction on punched cards was introduced by Joseph – Marie Jacquard

monster was published by Mary Shelley and were made available by project

20th Century

In 20th Century AI took modern shape and automated
further to a new form.

In 1950’s Early AI programs
like Samuel’s checkers program, Newell & Simon’s Logic Theorist,
Gelernter’s Geometry Engine were introduced

In 1956 AI was adopted at the
workshop held at Dartmouth college which was attended by Allen Newell, Herbert
Simon, John McCarthy, Marvin Minsky and Arthur Samuel became the founders and
leaders of AI research.

What Contributes to AI?

Artificial intelligence is a science and
technology based on disciplines such as Computer Science, Biology, Psychology,
Linguistics, Mathematics, and Engineering. A major thrust of AI is in the
development of computer functions associated with human intelligence, such as

What is AI Technique?

AI Technique is a manner to organize and
use the knowledge efficiently in such a way that:

It should be perceivable by the
people who provide it.

application’s in today’s society and plays an important role in our day to day
life in the fields such as Marketing, Finance, Medical, gaming and many other.
AI has been dominant in various fields as below:


AI plays an important role in games such
as chess, poker as it can think of large number of possible moves then human

Natural Language Processing

Natural language processing makes it
possible to interact with computer that understands natural language spoken by

Expert Systems

There are some applications which integrate
machines and software to provide explanation and advice to the users.

Vision Systems

These systems understand, interpret, and
comprehend visual input on the computer.

Speech Recognition

These systems are capable of hearing and
comprehending the language in term of sentences and their meanings while human
talks to it.

Handwriting Recognition

This system reads the text written on
paper or on a screen. It can recognize the shapes of the letters and convert it
into editable text.

Intelligent Robots

Robots have the sensors to detect physical
data from temperature, movement, sound, light, heat etc. and perform the task
given by human.

Programming with and without

A typical program has three major segments
input, processing and output. The comparison between regular programming and AI
programming is described in the below table:

Table 1: Programming with and
without AI


Regular Programming

AI Programming


In regular programming, input is
a sequence of alphanumeric symbols presented and stored as per some given set
of previously stipulated rules and that uses a limited set of communication
media such as keyboard, mouse, disc, etc.

In Artificial Intelligence
programming, the input may be a sight, sound, touch, smell or taste. Sight
means one dimensional symbol such as typed text, two dimensional objects or
three dimensional scenes. Sound input includes spoken language, music, noise
made by objects. Touch includes temperature, smoothness, resistance to
pressure. Smell input includes odors emanating from animate and inanimate
objects. And taste input includes sweet, sour, salty, bitter foodstuffs and


In regular programming,
processing means manipulation of the stored symbols by a set of previously
defined algorithms.

In AI programming, processing
includes knowledge representation and pattern matching, search, logic,
problem solving and learning.


In regular programming, output
is a sequence of alphanumeric symbols, may be in a given set of colors, that
represents the result of the processing and that is placed on such a medium
as a CRT screen, paper, or magnetic disk.

In AI programming, output can be
in the form of printed language and synthesized speech, manipulation of
physical objects or locomotion i.e., movement in space.
