3.  The biology of a computer is a very complex
and sophisticated piece of modern day
technology.
 I am going to show you the internal
components of this amazing creation.

4.  The processor is a very essential piece of any
computer it is the heart of the computer.
 It processes every data related action that the
computer performs.

5. RAM is very quickly accessed for
Flash memory is a very robust example: A word document would
form of memory and it retains be taken from the main storage
data in the absence of a power. (Hard Drive) And put into the RAM
for quick access. The data stored
in RAM is volatile meaning that
data is lost when power is
removed.

6. ROM (Read only memory) is a
firmware chip that is
programmed with specific data
EPROM (Electrically programmable when it is manufactured, The
read only memory) This chip can be data in this chip isdoes not go
erased withstrong UV Light when a charge is lost

7. Solid state drive(SSD)is a solid chip of
memory instead of the traditional
SATA Hard Drive rotating disks.
A SATA hard drive is a mass storage device which is
connected to the computer via a SATA cable

8. SCSI
A SCSI Hard Drive works the same as a
PATA or SATA Hard drive using magnetic
strips but the only difference is the
connecting port that they use, In this case
a SCSI port.

9. This is a network card it has a
Ethernet port so that a computer
can connect to the internet via
Ethernet connecting
Different types of BUS
would include: Parallel, and
serial, The most well known
BUS would be USB.
They communicate with the
processor using PCI bus.

• Type 1 cards are primarily used for adding additional ROM or RAM to
a computer.
• Type 2 cards are often used for modern and fax modem cards.
• Type 3 cards can be up to 10.5mm thick and because of this size it
can be used for portable disk drives.

11. An input device is a device that allows a user to input
into a computer for example a keyboard.
Here are some examples
of input device

12. An output device is a device which allows a user to put a
command into a computer and something will come back
out for example music.

13. The most common input/output interface
would be USB because it is practically fast and
quite cheap.
A not so commonly used input/output
interface but is extremely fast but slightly
more expensive than the common USB would
be the FireWire cable.

This is usually achieved with UV
