Computer or
computer literal translation of the English word COMPUTER, it was common
to use the English word which derived from the verb COMPUTE ie, by, and
release your computer or your computer on all sizes and types of
computers, whether used for the purpose of personal or in an institution
or company, or be used for specific in various industries, and now the
computer has become a key element in the various aspects of life,
ignorance is even using the computer illiteracy is true in this era.
The first computer back in the early forties of the twentieth century,
and was characterized by the magnitude of size and very slow and it
requires large areas and special equipment and the procedures for
dealing with complex needs to be specialists.
But over the fifty years following the emergence of the first computer
developments have taken place and spikes, representing the first stage
of the valves in the glass, then transistor stage which had been
invented by Laboratories Inc., "but"; thereby reducing the size of the
computer and its price and maintenance costs and cooled.
The stage microprocessor Processor and (any CPU on a single piece)
founded by Intel Corporation Intel pivotal step in the history of the
computer where you entered the then large companies racing circuit, such
as Zilog Zilog and Motorola, and Apple's Apple and Atari Atari.
In 1981 produced by the IBM's first personal device launched by the
personal computer of IBM IBM Personal Computer, and popularized the use
of this label even fired at all a small computer.
In 1989, Intel announced the emergence of processors (80486), which
contains a million transistor capable of implementation of 15 million
operations per second, and the year 1993 saw the birth of Pentium
"Pentium", or (80 586) styles and different speeds approaching 300
million pulse in Second, and able to perform for 64 binary number.
Computer and the human world is, "John von Neumann JOHN VON NEWMAN" the
first to study the makeup job for a person by observing how to solve
the problems, and found that the human being in order to solve a
specific problem, it is employing the senses in the collection of
elements of the problem and information, and then following that store
this information in memory, and then analyze the reason of the problem
and then find the appropriate solution from the reality of his
experience he has learned, and end up taking a particular decision,
where orders are issued to the muscles in the different member of the
implementation of the nerves and the role of the carrier in all stages
of this process.
As the memory of man is unable to absorb the information and data to at
the end of the used human modes of assistance that stores information
on it and then invoked at any time, through any of the units I own; so
it has invented a book reading and the recorded sound, video, visual and
other means of Save the data and information.
And noted, "Newman" is what has been applied in practice in the design
of the computer; Modules entry lead to a computer to play the five
senses, we find that there are several types of devices or input
devices, such as a keyboard KEYBOARD and mouse (MOUSE), scanner
(SCANNER), and the Registry reading light, and so on.
And requires the computer to the memory core internal MAIN MEMORY can
not be the device that works without a permanent communication CPU, and
partition logical memory component of a set of rooms nine each of eight
bits BITS, and action is based on work in the computer and all eight
bits BITS represent BYTE one byte which is in turn a character
alphabetical or numeric one.
The main memory associated with the central processing unit is limited
in its ability to storage; therefore been developing a number of storage
media assistance just like the situation in the human condition, we
find such arguments magnetic such as PVC soft (FLOPPY DISKS), and
cylinders of solid (HARD DISKS) and magnetic tapes MAGNETIC TAP, as well
as optical discs and cylinders OPTICAL DISKS Alumblyzrp of different
kinds.
