Input, Output and Storage Devices
  1. Input Devices
    1. Keyboard
      1. Underneath the keyboard letters are switches, they send the data through to the computer then that data gets changed to the letters and numbers.
      2. Mouse
        1. A mouse is connected to the computer so you can control what it does.
        2. T.V Controller
          1. Microphone
            1. Microphone converts sound waves into the audio signal. The diaphragm is located at the head of the microphone, this vibrates when sound waves hit.
            2. Webcam
              1. Joystick
                1. Scanner
                  1. Touch Screen Device
                    1. Xbox Controller
                      1. The Xbox controller sends information to the Console, that it is connected to, depending on the buttons you press. The buttons that you press contribute to what happens on the screen, which is connected to the console.
                      2. Barcode scanner
                        1. The scanning head shines a Led or a Laser light onto the barcode. The light reflects of the barcode(black the least light, white the most light). As the scanner moves past it causes an on - off pulse corresponding to the white and black stripes. Example - black black black white black black white black - this would be off off off on off off on. An electronic circuit on the scanner converts these pulses into zeros and ones. On the example before this would be - 11101101.
                      3. Output Devices
                        1. Printer
                          1. Data is sent to the printer via the computer. In the printer ink is put onto the paper that you want to print. The paper then comes out the printer with the ink on it where you want it.
                          2. Speaker
                            1. T.V Screen
                              1. Headphones
                                1. In the head of the headphones there are two wires, one of the wires carry the current into the coil from the stereo then the other one carries back again.
                                2. Plotter
                                  1. Computer Screen
                                    1. Light Pens
                                      1. Monitor
                                        1. Phone Sreen
                                          1. Projector
                                          2. Storage Devices
                                            1. Memory Stick
                                              1. A memory stick is a small SSD that uses flash memory cells that keep memory while they are off. They are better than hard disks because they have moving parts.
                                              2. hard disk
                                                1. A hard disk has a mechanical disk spinning around inside the drive then writes down the data.
                                                2. Pen Drive
                                                  1. Pen Drive consists of a small printed circuit board. The board provides a solid base for the Pen Drive's form and collects information. The circuit board has a small microchip inside it which makes the Pen Drive able to pull out information.
                                                  2. Floppy disk
                                                    1. A floppy disk reads and writes data to a small piece of metal plastic similar to an audio cassette tape.
                                                    2. Zip Drive
                                                      1. The zip drive has two parts to the head that interface with the computer to get the data. In the disk there is a quick spin cartridge like the flexible part of the floppy disk. Code is written here for storage. This is a portable device.
