Unit 3-P1
Internal system unit components
Processor
A processor is like the brain of your computer because it tells you what you need to do and
when you have to do it
...
The CPU’s responsibilities is to ensure it understands and performs most of the
instructions that is given from the computer and software, furthermore many calculations
take place within this component
...
The CPU also consists a program counter; this will keep a location of the CPU’s
place in the program
...
One of the most essential parts motherboards
can hold is the central processing unit known as (CPU), I have written the definition of the
CPU above
...
These chips that are stored on the
motherboard are also knows as motherboard’s chipset
...
With this program data flow can be controlled between the
computer operating system, it is designed to function with a numerous of devices that
create a complimentary system chipset
...

The BIOS software checks every hardware connection and it also has the ability to trace the
devices, this is when the operating system has been entered the computer memory
...
This ROM chip will make sure that BIOS will be consistently available
and prevent any damages by disk failures, with BIOS computers could possibly also boot up
which means start up the computer system
...
If information about a specific device has been altered, The BIOS
program will only be required to be changed
...
Furthermore operating systems or applications will not be required to be
changed
...

...
It is usually contained in hard
material some of it has very high capacity
...
Many people also use this device to
store documents that relate to their jobs, as it has the ability to store a lot of information
depending on the size
...
This is
also known as serial advanced technology attachment, this configuration is very fast and it is

a significantly enhanced serial version of the PATA interface
...
The
interface for the hard drive is designed for simply installation
...


Another example of a hard drive configuration is IDE, this is also known as integrated
development environment
...
IDE is not the original technical name for
the interface standard, the actual name is ATA also known as Attachment
...
With the use of IDE, web pages can also be created and design
on the Internet by using the software Dreamweaver
...
g
...
You can simply plug into the side of your computer that has the USB
slot and you will be able to access the USB file within the computer it is plugged into
...
USB flash drives do not have the ability to store a lot of data, as there
capacity is normally very small
...
Many people don’t use hard drives due to their size; therefore it could be
difficult to hold on to them for particular reason
...




FireWire

FireWire is one of Apple’s creation, it is a process of transferring information between
devices instantly
...
FireWire are hot pluggable
devices, this means that the device could be connected and disconnected at any particular
time even if the power is still turned on
...
Furthermore they are often used
to connect to printers, computers and devices that require high bandwidth
...

One of the most popular parallel port is a printer port that is known as Centronics port
...





Internal memory (e
...
RAM, ROM, cache)
RAM
A RAM in a computer system is usually referred as the system’s memory, however its
abbreviation is random access memory
...
Due to information being
placed in random locations, computers will have the ability to access information much
faster
...

ROM
ROM is located in the computer memory, it also known as read-only memory
...
Rom holds codes that will enable computer system to
start up or restored whenever it is turned on
...
If an incident occurs and the power of the computer
system is turned off, the data in ROM will not be lost or gone
...










Specialised cards (e
...
network, graphic cards)
Graphic cards
The Graphics card is the component in your computer that handles generating the signals
that are sent to your monitor
...
It determines how good your graphics, resolution and capability is on
your computer or game console
...

Furthermore the better the graphic card, the better image people will receive on their
screen
...
There are different types of network cards as they are designed for specific
purposes; some of these network cards have the ability to serve more than one network,
which could be very useful for businesses
...
g
...
There different kinds of printers
...




Monitors
A monitor is the screen that shows the images from the computer
...

Input devices (e
...
camera/webcam, scanner, and microphone)
Cameras
Cameras is a device which is used for taking pictures, they can either be digital or film
cameras
...
When pictures have been taken, the images will instantly show on
the screen
...
There is also film camera which is older than
digital camera, a film camera records images on a roll of film and stores it on a film in an
analogy format, they provide increased dynamic range in a an image
...






Scanners
A Scanner is a photocopier for your computer, they are devices that allow you to convert
images into a format that can be edited by a computer, and they can capture images,
posters, pages of magazines and any photographic prints
...


















Cabling (e
...
optical, twisted pair)
Optical cabling

Optical cables are cables that contain a several amount of fibres, it is covered with a hard
layer of resin
...
Optical
cables contain a certain material that will protect the environment; it is a tube like material
that will be covered around the cable
...
Optical cables are better options rather
than using a regular wire due to the level of protection, however, it costs significantly more
...















Twisted pair cabling

Twisted pair cables consist two individually separated wires twisted around each other, this
use of cabling eases crosstalk and electromagnetic induction
...
Particular telephone sets and desktop places require multiple
connections; twisted pair cables are occasionally installed in two or more pairs with a single
cable
