We learned how to connect machine with computer by one line，how to put the wires from the host computer and connected to the computer, you can start the operation.

        Computer consists of a host is main part, the output device is display,input devices are keyboard and mouse .

        Teacher showed us many kinds of the wire type.
       Setting up the computer is difficult for me , but teacher taught me how to do it , it's better than before.
       Maybe i should learn more about computer and remember some knowledge.
