- Input Devices
- Keyboard
- Underneath the keyboard letters are
switches, they send the data through
to the computer then that data gets
changed to the letters and numbers.

- Barcode scanner
- 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.

- Storage Devices
- Memory Stick
- 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.

- hard disk
- A hard disk has a mechanical disk spinning
around inside the drive then writes down the
data.

- Pen Drive
- 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.

- Floppy disk
- A floppy disk reads and writes data
to a small piece of metal plastic
similar to an audio cassette tape.

- Zip Drive
- 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.
