Computer is a machine with an
intricate network of elektronic circuit that operates switches or
magnetizes-tiny metal cores. The switches like the cores,are capable of being
in one of two posible states,that is on or off: magnetizes or demagtizes. The
machine is capable of storing and manipulating number, letter and character.
The basics idea of a computer is that we can make the machine do what we want
by puttinh signals that turn certain switches on and turn other off, or that
magnetizes or do not magnetizes the cores.

The computer is a machine with an
intricate network of electronic circuit, the basic job computer is the
proccesing of information. Computer can defined as devices, which accept
information in the form of instruction called a program and character,called
data perform mathamatical and or logical operations on the information, and
that supply result of this operation. The program, or part of it, which tells
the computer what do on data, which vide the information needed to solve the
problem, are kept inside the computyer
in place called memory.
Computer are thought to to have
many remarkable powers. However, most computers, wheter large or small, have
three basic capabilities. First, computer has circuits for priming arithmatics
operation, such as : addition, substrction, division, mu;tplication and
exposition. Second, computer have a means of communicating of the users. After
all, if we could not feed information in and get result back, these machine
would not be of much use. However, certain computer (commonly mini computers
and microcomputer ) are used to control directly thing such as robots,
aircracft navigation system, medical instrument,etc.
Some of the common methods of
inputing informatiopn are to used punched cards, magnetic tape, disk and
terminals. sThe computer’s input devices (which might be a card reader, a tape
drive, depending in the medium used in inputing information) read the
information into the computer. For outputting information, two common devices
used printer, which print the new information on paper, or CRT displays screen,
which shows the result on tv like screen.
Computer have circuits,which can
make decision, which computers can make are nit of the type , ‘who would win a
war beetwen two countries ?’ or ‘who who is the riches person in the world?’ .
Unfortuntely, the computer can only decide three things namely: is one number
less than another? It what to do and gives it the
A computer can solve a series of
problem and make hundreds, even thousends. Of logical decision without becoming
tired or bored. It can find the solutoion to problem in a fraction of the time
human beinhs to do the job. A computer can replace people in dull, routine
tasks, but ih has no originality, it works according ti the instruction given
to it and can not exercise any value judgments. There is time when a computers
seems to operate like mechanical ‘brain’ , but its achievments are limited by
the minds of human beings. A computer cannot do anything unless a person tells It what to do and gives it the appropriate
information, but because electric pulse can move at the speed of light, a
computer can carry out vast numbers of arithmetic-logical operation almost
instantaneously, a person can do everything a computer ca do, but in many cases
that person will be deal long before the job was finished.
