Computer Input Out put Device

We have discussed the memory of the computer, which works with information, and the device to store information. Technical Data used in the field explained in computer courses in Rawalpindi. Now these information are to be fed to the computer (Input) and also, we are to get the processed information or result (output).

The primary input device is the Keyboard. It is attached to the computer through a cord in the specific port provided in the motherboard. Whenever you press any key of the keyboard and then press the Enter key an input, correct or incorrect, goes to the computer CPU. However, there are many ot her input devices – e.g. the computer can read input from the Hard disk, CD/DVD or Floppy Diskettes, Modem, Mouse, Joystick, etc. Again one computer can give input/output to another if they are connected through a ventral computer (called server) as done in LAN (Local Area Network) orby other types of networking. All these input devices, except the Keyboard, can act also as the output device to receive the results . Some more details of computer courses in rawalpindi are as under.

 However, the Touch-Screen Keyboard acts as both input and output device. Amongst the out put devices we have two specific instruments – one is the Video Monitor, which constantly displays the results of processed input in the screen to monitor you through your work. It also helps you see the command, or data inputs you are giving to the computer, but not all. The other is the printer, which prints the results in paper, if you give command to the computer to do so.
