What Is A Computer?
We
enter
a picture to the computer and format it (change its color…) then
the computer will
produce
the picture after it has been modified and
stored
it
We
enter
numbers to the computer the computer will calculate these
numbers(add…) then the computer will
produce
the results and
stored
it
So the Computers can perform four general operations:
Input(data)
Process (depend on the program that we use)
Output (information)
Storage
What Is A Computer?
computer is an electronic device, that can accept data
(input), manipulate data (process), and produce
information (output) ,and it is operating under the control
of instructions (software).

The difference between data and information
Exersize :
We
enter
Sales and Cost
to the computer the
computer will calculate these numbers(add…) then
the computer will
produce
the total of the sales
,the total of the cost the
