Computer's power point

1. COMPUTERS

2. INTRODUCTION
• A computer is a general purpose device that can be
programmed to carry out a set of arithmetic or
logical operations automatically. Since a sequence
of operations can be readily changed, the computer
can solve more than one kind of problem.

3. HISTORY
• The first mechanical calculator, a predecessor of the
digital computer, was invented in 1642 by the
French mathematician Blaise Pascal. That device
was using a series of wheels of ten teeth in which
each of the teeth was representing a digit from 0 to
9. The wheels were connected in such a way that
they could add numbers making them advance the
correct number of teeth. In 1670 the philosopher
and mathematical German Gottfried Wilhelm Leibniz
perfected this machine and invented one that also it
could multiply.

4. INEVENTORS OF THE FIRST
COMPUTERS
ATANASOFF AND BERRY. A former patent of a
device that great people believed that it was the first
computer rigs l electronic it was invalidated in 1973
on order of a federal court, and officially the credit
was given to John V. Atanasoff like the inventor. The
Dr. Atanasoff, professor of the State University of
Iowa, developed the first digital electronic computer
between the years from 1937 to 1942. It called to his
invention the computer Atanas off-Berry, ó alone
ABC (Atanasoff Berry Computer). A graduated
student, Cliffo rd Berry, him turned out to be a useful
help in the construction.

6. ETIMOLOGY
• The first uses of the word "computer" was recorded
in 1613 in to book called " The yong mans gleanings
" by English writer Richard Braithwait I haue read
the truest computer of Steal, and the best
Arithmetician that euer breathed, and have reduceth
thy dayes into to short number. It referred to to
person who carried out calculations, or
computations, and the word continued with the
same meaning until the middle of the 20th century.
From the end of the 19th century the word began to
take on its relative dwells meaning, to machine that
carries out computations.

7. COMPUTERS IN THE FUTURE
• In the future, as they indicate the specialized means of
the United States that have had the opportunity to see
more in depth this technology, the computers will be
much more complete and the users will benefit from
added options. When we touch an object on the tactile
screen of a computer or of a tablet we will feel the tact of
the component of factory with the one that has been
created. The sensors of the computers are going to be
capable of transmitting the same sensation that we feel
the persons when we touch an object and notice the
material with the one that has been created.
