Unit - 2 Why I chose the Components
Gamer
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
Photographer
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

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…

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.

The Utilities in Windows XP
Defragmentation
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.
