User Side Factors
·        Download Speed – Download speed measures how fast it takes for a file to download to your computer. Download speed is measured normally in ‘MB/S’ or ‘KB/S’ these mean Megabytes and Kilobytes per second. Download speed is important in any computer, it reduces how long it takes for websites to load and it can also speed up updates on your computer. In order for my website to be accessible for everyone is by trying to minimalize how much data is on my site so it has reasonable loading times for any computer. To do this I can check my images are the right size, rather than compressing much larger images.
·        Web Browser- Web browsers are applications used to view sites from the World Wide Web.  There are 4 main types of web browser, these are Internet Explorer, Google Chrome, Mozilla Firefox and Safari, which is exclusive to Apple products e.g. IMac, IPad and IPhones. As I’m designing a website it is crucial that the user has at least one of these browsers so they can actually view the product.
·        Cache Memory – Applications can store certain data in the computers system memory or RAM. Websites can load quicker because of this as it can save videos, images, text and can also remember your password if allowed. This will reduce the loading time of my website making it a much more efficient experience for the user.
·        Processor speed – this is worked out by how fast a processing cycle is completed. Also known as ‘clock speed’ it is measured in megahertz (MHz) and gigahertz (GHz). If the viewer doesn’t have a good clock speed they won’t be able to view images and videos without lagging.
Server Side Factors
·        File Types – There is a large variety of file types. These are things such as Bitmaps, JPG, GIF, Vector etc. An example is a JPEG file. This file will contain an image as this is what JPEGS are. The computer uses a file extension, this identifies what the file is. For example a JPEG is a compressed lower quality version of a ‘wav.’ Because of this, it has a much shorter loading time compared to that of a wav. File. In order for my website to be a success I will need to have a good balance in the quality of my videos and images for optimum loading times. The users of my website will also have the correct file extension software so they are able to view the images and videos.
Web Server Capacity
·        Available Bandwidth – Bandwidth is the maximum data transfer rate of a network or internet connection. It gives you information on how much data is transmitted through a connection and how long this data took to be transmitted. It is measured in Mbps, standing for megabytes per second. This gives the user an idea how long it will take them to download a file, for example if you were downloading a file which was 100MB and you had a bandwidth of 5MBS it would take you 20 seconds to download. If the user only has a cable modem, which provides up to 25MBPS it will more than likely take longer to load the webpage compared with a user who has a gigabit Ethernet connection, which has a bandwidth of 1000MBPS, so when designing my website I need to make sure everyone is able to view it no matter what connection they have.
·        Executions To Be Performed Before Page Load – every time a website is loaded all of the data for the site has to be retrieved, things such as images, text, videos and the CSS style. This process can take a long time depending on the bandwidth, but using JavaScript can boost the loading time overall.

·        Number of Hits – a hit is the number of everything on the page and the page itself is a hit. For example, if a site had 6 images and 3 videos this site would have 10 hits. The higher the amount of hits on a site the longer the loading time will be, this is why I will try to keep a reasonable amount of hits per page.

Purpose – I am designing a product that promotes a number of aspects to Arsenal Football Club. My aim is to promote different areas of the football club and inform fans on information, to do this I will use different multi media types. What I am aiming to inform supporters on is the team, upcoming fixtures and previous results and news about the club. I will also inform fans on a number of different things including injury news and transfer news and rumours. To make my product entertaining, I will use different media types. My target audience is fans of Arsenal.
Multimedia Types
Photos: These are still images that have been taken by cameras. These are useful for the aims of my product as it can add colour to the page and can also be used as a more interesting form to give information compared to text. A way in which I will use photographs with my product will be as a link for example, in the news section, when you click on a picture, it will take you straight to the relevant news story. This makes it easier to click on news stories as well as you don’t have to try and click on small text.
Videos: A video uses moving images and sound. Videos are one of the most popular ways of sharing information. Instead of giving the viewers an image with supporting text, you can just give them a video with an audio recording over, this means the viewer can see what’s going on as well as it being described to them without scrolling down the page and losing the image. Another advantage of using videos is that I can show highlights of games, which accomplishes my aim because not all of the games are shown on TV and people may miss the game, so it means they are always up to date. I can also show interviews with players and staff which will be in the interest of some viewers.
Text: Text is the most simple, but a necessary form of multimedia. It’s will be used all over my site, one of the most important ways will be links to different sections of the website, for example along the top of my site will be words such as, ‘Photo’s’ ‘News’ ‘Videos’ and when you click on these it will take you to the pages relevant. Another way I will use it is to feed the supporters information that doesn’t need multimedia such as videos and images for example, when I post things such as injury lists.

What is a database?
A database is used as an organized mechanism that is able to store, manage and retrieve information. They make this possible by the use of tables. These tables consist of columns and rows. Every column has a different attribute and every row and every row corresponds to a single record. Although they are similar to spread sheets databases are in fact a lot more powerful in the way data is manipulated. There is a wide range of actions that databases can do that spread sheets cant, for example:
Update records in bulk
Perform complex calculations
Retrieve all records in a certain criteria
Cross-reference records in different tables 
All of the above examples give a good insight as to why databases are much more efficient than paper based solutions. This is because if you were to update in bulk on paper it could take you hours whereas on a computer based data base it could be done in seconds, and you can easily see if you made a mistake and it’s simple to correct it. Similarly if you were to try to take on complex calculations on paper based, this would not only take you personally to be good at maths, but could also take a long amount of time, whereas a database can take minimal effort and time without making mistakes.
Forms
Database forms are often referred to as “data entry screens”. They are interfaces which are used to work with your data and normally contain command buttons, which all perform different commands. A way to create databases without these forms is to edit the data in the table’s datasheets. Although a lot of database software and users prefer forms for viewing, entering and editing data. Another bonus of using forms is using command buttons, you can program certain buttons to choose which data shows up on the form, open different forms, and do much more, such as, you could have specific form for a customer, with command buttons, you could have a command button that would open this customers order form, which you can then edit. Forms can also be used as a method of security, this is because you can create forms that will only show certain fields and will only allow certain operations to be performed. These are more efficient than paper based solutions because you would need a number of sheets for each customer alone, so you would have less chance of losing it. It also allows security, which isn’t possible on paper based solutions. 
Reports
Database reports present data from a database, these reports can be printed from the database which allows you to view the data quickly and easily. Reports are the summary of your database they can present the information visually in the form of graphs and charts etc. They are more efficient than paper base solutions because they automatically summarise the data, they also can automatically and instantly present the data in forms of graphs and charts etc. whereas paper based solutions would require you personally to summarise and present the data, which could take a long time.
Switchboards
A switchboard is a form that contains a navigation menu which allows you to switch to other queries, reports and forms in your database. These are more efficient than paper based solutions because on a paper based solution you would have to navigate your own way around sheets and sheets of paper whereas on a database with switc

An operating system is a layer of control which allows the user to interface between the hardware and the software. The operating system is in charge of managing the computer and it allows the user to run software. 

There are many different operating systems available, but the most popular ones are Windows, Mac OS X and Linux. 


Most modern operating systems have a GUI and multitasking features. A GUI is graphic user interface and it is what you see on your monitor, it allows you to easily access installed programs. Multitasking is when you run two or more programs at a given time, early systems did not support this, so when you were running painting software and you wanted to change to text editor you would have to close the painting software in order to run the other piece of software.

Modern computers allow you to run almost limitless software at the same time as a result of large amounts of RAM and powerful multi core CPUS.

The three main types of operating systems are Linux, Windows and Mac OS X.

Most operating systems now come with their own security, for example Windows 8 features Windows Defender, this is a program that runs in the background and notifies you when you need to take an action, it also allows you to scan your computer for malware if your computer is running slow or isn’t working, it also protects you online and prevents you clicking on virus links or emails containing a virus. They also have internet security, this will prevent you from downloading files that contain viruses.  

 

Windows features ‘My Documents, My Pictures, My Music, My Videos and Downloads’ this allows you to manage your files as soon as you get the computer and want to transfer documents across from an old computer etc. All files that you download should automatically go into your ‘Download’ folder, but you are able to choose where your files save to. You are also able to create folders in these main folders to make your files neater and easier now to navigate. In windows it is also possible to have more than one user on the computer at the time and you can leave a user running in the background.

 

Machine and peripheral management manages all the devices installed on the computer, the sort of things that machine and peripheral management manages are things such as external storage devices, phones, cameras etc. This allows transfers of things such as music, pictures and videos; it also allows you to back up devices such as mobile phones.
