2. Storing

The computer
must be able to process or process data. The data also exists a wide variety
and range of processing requirements are also very spacious. In addition, the
computer also must be able to store data. Although for the purposes and the
short term, to be able to store pieces of data. Computers also have to be able
to move data between itself and the outside world. The computer's operating
region is of devices that serve the data source / destination data. When data
is sent or received to a device that is connected directly to the computer,
called the input-output, and the device is known as peripherals. If the data
transfer occurs in a considerable distance (remote device) then the process is
called data communication. Except its functions over the above functions, the
computer also serves as the control data. In a computer system, a control unit
set up computer resources and control the inner workings of a functional part
in response to the instruction instruction.
