2. Cpu’s
• They issue instructions to different computer
programs to do basic operations. Cpu speed is
measured in bits and it determines how first it
can work. The cpu compatibility matters to
see whether it can support the updates
available.

3. memory
• Ram is able to store data but only temporarily so you
will lose that data when it loses power. There are
many types of ram such as SDR, DDR, DDR2, DDR3,
static, cache and dynamic. These are all different
types of ram and are also temporary storage devices.
• Eprom (erasable program read only memory) this is
able to retain everything that is stored on it even
without any external power source.

4. memory
• Flash memory permanent storage is a solid
state drive and also can only be erased one
page at a time and can hold data even without
an external power source.

5. Adapter cards
• PCI are able to provide extra features which
are able to be given by the motherboard. The
PCI and PCI/e give different types of available
features. They are compatible with the
computer by connecting through the different
bustypes.

6. Storage devices
• Sata (serial advanced technology attachment)
is a computer bus interface which connects all
the large hard drive devices such as the optical
drive and hard disk drive.
• Pata (parallel attachment) is the standard
interface connection for devices such as HDD,
FDD, floppy drives and Optical Disk drive.

7. Storage devices
• SCSI gives a physical connection between the
computer and the peripheral devices. It can
change commands, protocols and optical
interfaces.
• The solid state drive is able to hold data and
for the user to be able to access it as they
would with a hard drive. It has no moving
parts so it is less likely to break

8. Input and output devices
• Input devices such as the keyboard,
microphones and games controllers all input
into the computer.
• while output devices such as the printer,
monitor and speakers give out from the
computer. Different interfaces allow them to
communicate with the computer
