Unit - 2 Why I chose the Components
Motherboard – I chose the Asus motherboard due to its ability to handle triple channel RAM,
therefore making the response time from it smaller. The board like many others supports DDR3 RAM and will also support a high end graphics card that has an interface of PCIe 2.0 (x16).

CPU – I have chosen in i7 960 Quad Core because of its 3.2GHz clock speed therefore making this a faster processer and this will make it more capable of running higher spec games. RAM – For the RAM I have decided to take a 6GB triple channel. The advantage to having more than one stick of ram is the CPU will send the data that it has processed down the multiple channels, this will make it faster. GPU – I have taken the Point of View GeFORCE GTX 570. Although this particular Graphics Card comes with a game this was not the determining factor to which I choose. The Card has 2GB of RAM built on to it with an interface of PCIe 2.0 (x16), the interface is the biggest factor in choosing a Graphics Card because it needs to be compatible with the MoBo. Sound Card – The Asus Xonar has multiple inputs and outputs; with its Dolby 7.1 surround sound this particular sound card will provide the gamer with two extra speaker ports, the two extra ports will provide a gamer will not just a front left, right and rear left, right but also above left and right. This will create a quality output of sound from every direction. PSU – For the current setup the PC won’t use 1.2KW but if the user wanted to upgrade the computer with better parts that released more heat, they would still have the options to upgrade from air cooling to water. Optical Drives – A Blu Ray drive will allow the use of CD’s, DVD’s and Blu Ray disks, although many new PC games are on DVD’s the gamer can still use older games that are on CD. The PC will be, to some extent, future proof due to the ability to play Blu Ray disks. HDD – I have chosen a 2TB HDD because a gamer will most probably have multiple games
11/10/11 Page 9

Unit - 2
and would want to download certain additions to games such as Map Packs and Updates. Fans – I have decided to add 2 more fans to keep the components cool. Even though these are unessential it will make it possible to overclock the components without the need to spend extra money on the cooling for it. When deciding what Mouse, Keyboard, Monitor and Headset to choose I decided to look at online reviews and balance the choice between them and my personal preference. Case – The case was one of the easier components to choose. Mainly because it had to fit an ATX motherboard in it and have enough space to fit a Blu Ray player and a HDD. Although many gamers like a good looking case I don’t see the point in spending an excessive amount on this component.

Why I chose the Components
Motherboard – I have chosen to use a Gigabyte GA-PH67A-UD3-B3 motherboard for the photographer’s computer. Although this MoBo is a lower spec that the previous one it will still handle the other components I have taken. CPU – For this build I have taken an Intel Core i5 Quad Core. This CPU has a slightly high clock speed of 3.3GHz but, I mainly took this one on the basis that the user would be using less demanding software and that the other components would be more expensive compared to the previous build. RAM – I have decided to take a modest but acceptable 4GB Corsair XMS3, though thinking about it maybe this is too small. Although this certain choice takes advantage of Dual Channel technology the photographer will most probably be using several programs at once. The advantage to having a larger RAM would be that the programs would run smoother. But as I have taken 4GB there is the option to upgrade at a relatively small cost if it is too little memory. GPU – I have taken a Point of View 3GB GeFORCE GTX 590. Compared to the 2.5GB 570
11/10/11 Page 10

version of this card, it will run faster and give better visual performance. With an interface of PCIe 2.0 (x16) it is compatible in many modern Motherboards. At £707 it is the most expensive internal component, but a photographer would need unbelievable levels of performance. PSU – I have decided to take a 1KW PSU, although I have lost 200W compared to the Gamers PC, the PC doesn’t contain a Sound Card. The user will still have enough power to upgrade if they wish and the option to convert from air cooling to water. Optical Drives – I have taken the same Blu Ray player from the Gamers PC. Although most picture now only take up a maximum of 10-20Mb; the quality and resolution of these will continue to increase so will the file size. If the user had a client who had many photos taken he would be able to burn them either to DVD or Blu Ray depending on the total file size. Also the Optical Drive will allow the photographer to install editing software ect… HDD – I have built this PC with 2 Western Digital 750GB Hard Drives. I have taken two so the user can back up his data, or use it as extra storage space if he fills up the first one. For example if the first one failed and he had backed up on the second he would not have lost all their work and income. Mouse and Keyboard – I have taken a basic mouse and keyboard because the user doesn’t really need a specialist mouse. Monitor – I have taken an Ezio ColourEdge CG243W monitor. I have taken this monitor from the colour confidence website. I decided to look at this website after it was

recommended to me. Although this monitor is on the expensive side it will not disappoint the user. The photographer will need a monitor will such a good colour resolution because what is seen on the screen has to come out on the paper. Graphics Tablet – The Hanvon ArtMaster graphics tablet has also come from the colour confidence website. Although this isn’t always essential I have decided to take on just to be on the safe side. Case – Again; just like the previous build I have taken a gaming case. Although this isn’t a gaming PC the components would get just as hot and need the extra fans.

The Purpose of an Operation System (OS)
An OS is a group of programs that manage the internal components of the PC and it also provides a common service to the user’s software. Without an Operating System the user cannot run a program unless it is a self-booting application. Operating Systems can be found on a number of modern electrical devices such as Mobile Phones, Games Consoles, Supercomputers and Web Servers. There are many different OS’s the most popular being Android, Linux, Mac OS X and Microsoft Windows. Each OS has many different versions; for example Microsoft Windows is now at 7 whereas Linux is well over 20. There are five different types of OS; Real-time, Multi-user vs Single-user, Multi-tasking vs Single-tasking, Distributed and Embedded. A real time OS is a Multi-tasking operating system that aims to run real time applications. Multi-user vs Single-user operating systems allow more than one user to be online at one time. These versions are more commonly used in schools, colleges and the work place. An operating system consists of many parts. One of the most important is the Kernel. The Kernel is the main components of many operating systems; it is a bridge between the applications and the data processing done by the hardware. The Kernels main function is to manage the computers resources and allow other programs to run and use these resources. This part of the operating system controls how memory is read and written, the order in which processes are executed and how information is received and sent by devices such and your keyboard and mouse. As many programs that will be installed on to the computer cannot interact directly with the hardware the OS is in place so this can happen. For hardware functions such as input, output and memory allocation, the OS acts as an bridge between an application and the

PC’s hardware.

The Magnifier – This was first included as a
sample in Windows 95 and was made standard content in the release of Windows 98. The Magnifier is in the OS to help the visually impaired, it zooms in on the area around the cursor, in Windows XP it could zoom in 9 times, in Vista it was upgraded to 16 times zoom in Windows 7 the magnifier was given extra content, there now is 3 different ways to use it, it can be docked at the top of the monitor, it can be a lens which creates a box around the cursor and enlarges anything inside it or you can have full screen magnification. Also it can

now zoom to 1600% its original size. Lens Magnifcation

On Screen Keyboard –

This allows the user to type without having a keyboard. This can be

used in replacement of a keyboard or until you get a keyboard. On Vista the keyboard had a blue background with white and grey keys, the windows key was also coloured in the colours of the windows logo. Whereas in 7 the keyboards design has changed a lot. The keys are now black with white text and the windows button in no longer coloured.

Narrator – Narrator is designed to help the visually impaired use their computer applications and
install other software. The Narrator that was installed to the Vista OS hasn’t been changed and the one in 7 is exactly the same.

internet files, empting the recycle bin, compressing files that haven’t been uses for a while. When opening the disk cleanup you will be asked which storage device you would like to be cleaned up.

You can also choose which file get compressed or deleted by the cleanup.

Disk Defragmenter –

The defragmenter is designed to increase access speeds to documents

and programs by rearranging the data on the hard drive so all relevant data is grouped together. Whilst the defrag is happening the performance of the PC drops considerably.


Page 18

Unit - 2

System Restore – By using System Restore you can restore your computer to an existing restore
point or if you don’t have one, create a restore point. System Restore backs up system files and saves them for later recovery; it will also back up some hardware drivers.

You can restore your System to a point before a certain update, for example in the image above the user can revert the computer to the same state it was in before the windows updates.

Task Scheduler – The task scheduler can be used to launch certain programs and other features
such as defrag, anti-virus ect…


Page 19

Unit - 2

Resource Monitor – This is a system application that allows the user to view information about
the use of the CPU, Memory, Disk and Network and software applications. This application is available in Windows Vista and onwards (my laptop doesn’t have it installed even though it is running Vista).

Windows Easy Transfer – This is a file transferring program that is included in Windows newer
OS’s which allows the movement of files and settings between two PCs’. Although it is included as standard in the OS’s after XP it can now be downloaded into XP.


Page 20

Unit - 2

The files can transferred through and Easy Transfer Cable, A Network or a USB or External Hard Drive. Windows 7 also includes Windows Easy Transfer Reports this makes it possible for the user to track what transfers have been made, and which PC’s the files have been transferred between.

Backup and Restore – The user can use this component of the Windows OS to create a Backup
of their PC. It is included in Windows Vista and later. It is the replacement for NTBackup. The user can backup what they like or they can do a Complete PC Backup which creates an image of the PC including the OS. This can then be restored through the Windows Recovery Environment either to the same machine or a different one.

Jump lists

– Jump List was is a new feature that was added to windows 7. It makes finding

recently used documents a lot easier. When the icons on the task bar are right clicked on a jump list will appear with all the recently used documents and the pined documents.

Snap – Snap was also introduced in to Windows 7.

It allows the user to ‘split’ their screen in half

and have two windows open at once. This makes researching and documenting a lot easier.


Page 23

Unit - 2

Windows Search – This allows the user to find all the documents that contain a certain word
with in its name, not only will it find documents but will also find programs and internet history. By typing in the key word in to the search bar on the task menu and pressing enter a windows explorer will open containing all the relevant files.

Shake – This is also a new feature in to windows, it allows the user to minimize all but the program
they are using by clicking and holding the window they want open and shaking it. All the windows can be re-opened by doing the same again.

And after a quick shake;

And by shaking it again I will re-open all the windows;

Unit - 2

Peek – Peek allows the user to see what is going on in each window without having to open them.
This feature is also a live video feed, so if you are playing a Youtube video in the window it will continue to play in the task bar.

For example I have hovered over my Visual Studio icon and received a sneek peek at what is going on in the window. Also by hovering over the show desktop button on the left of the task bar I also get a peek at the desktop and the locations of the other windows.


Page 27

Unit - 2

Snipping Tool – This cool little gadget was introduced in to Windows Vista and allows the user to
take little snippets of a page without having to crop a print screened image.

That is a cropped image because you cannot make a snippet of the snipping tool program.


Page 28

Unit - 2
Once I have taken my snippet of the window, a new window will open with the image I have just taken and it allows me to edit the image by rubbing parts out, adding extra lines ect…

The Utilities in Windows XP
When a user activates the defrag the computers performance drops considerably, the computer uses the RAM and the HDD together to move around the data stored on the HDD so all common data is stored together. By doing this the performance of the HDD is increase because of the data for one file is together meaning the file will be found and read quicker.

The Backup utility is a wizard to allow users to back up all the data on the PC on to DVD’s or Blu Ray disks. Although this doesn’t improve the performance of the computer; you will still have all your data, your OS ect… if your computer malfunctions.


Page 29

Unit - 2

Disk Cleanup
Disk cleanup is a maintenance utility that is designed to free up space on your hard drives and other forms of storage. The user can chose from a list of options which files the cleanup will find a delete, for example it can be used to delete files that are no longer used, temporary internet files, everything in your recycle bin and many other files. Besides deleting files it can be used to compress files that have not been accessed for a while.

This is a system utility that allows you to troubleshoot the Microsoft Windows startup process. It can be used to disable the startup of certain programs when the computer is turned on. When a program it is automatically set to startup when the computer Is booted up. By stopping the programs from booting up the computer will load faster but the program will take longer to load the first time it is opened.


Page 30

Unit - 2

Windows Task Scheduler
By using this utility the user can launch a program at a pre-defined time, for instance the Anti-Virus can be set to run every 10 days. Although this may seem to relive the user of remembering to launch the programs, they will still need to have the computer turned on.

The screen magnifier is the program that helps the visually impaired use Microsoft Windows. When the user runs this program it creates a small bar at the top of the screen that enlarges everything that is level with the cursor. In Windows XP it could magnify up to 9 times its normal size.


Page 31

Unit - 2

The narrator tool help the visually impaired use Microsoft windows, it will read out dialog boxes and windows controls. Although windows recommends the user goes and gets a full function screen reader this built in one can help them install it.

On Screen Keyboard
This utility can be used in replacement of your keyboard. If you do not have a keyboard this can be used until one is purchased, or if you have a touch screen PC this can be used instead of purchasing a keyboard.

Do the utilities increase system performance? Defragmentation –
The Defrag utility increases the performance of you HDD. Although this

decreases performance whilst in progress it will increase performance once it has finished.

Backup – The Backup will not increase the performance of your computer but will allow you to
create disks containing all the data about your PC.

Disk Cleanup – This utility will again increase the performance of your Hard Drive. MsConfig – MsConfig will increase system performance by stopping programs from booting up
when the PC is turned on.
