Liam Soper’s Multimedia product review 

The product  does meet its purpose because it is simple and easy to use.  The color used works well because the different shades of blue stand out it is also bright and stands out well. Also the logo stands out because of the yellow and white. The shapes make  effect that it is a football. AlI Buttons work also added like the feature which makes the buttons pulse. The news page is very well set out because it tells about recent news happening within the PE department. Also the information page is well set out; there is enough space for all the information about the department to put in there.

All of the media elements are appropriate and relevant to the department, all of the pictures are of the school PE facilities and they are all photos that he took himself. His project contains no broken links or errors.

The project is professional because it has the logo on every slide which is important otherwise it wont look professional or official . The layout is nice and it also had good animations and transactions. The colors also look good together and stand out, this makes it look professional. The pictures and text are set out well and don’t overlap but still covers most of the empty space.

Recommendations 

·         Add video footage.

·         Make the heading stand out more.

·         Make the logo bigger so that it stands out more.

·         Make sure everything in line so it looks more professional

Security Risks

Hacking

Hacking when someone finds a weakness in a computer system or network then exploits it this could involve stealing data or deleting it is mostly used to steal valuable data.

Identity Theft

Identity theft is stealing someone else’s identity and personal information this could involve creating false websites so you can steal people’s bank details, name and address and other valuable information such a credit card details, Identity theft over the Internet happens all the

Time because people put all there details on the website before checking it’s a safe and secure site.

Viruses

Viruses are made to corrupt or steal data from another computer; they are normally hidden in files downloaded from the Internet or in emails. Viruses are dangerous to the computer by performing actions like closing down anti-virus software and stopping the computer from performing basic actions until the virus is removed the computer will be unstable and unsecure

Security Protection Mechanisms

Firewalls

 A firewall is like a barrier if the firewall is on then it will stop anything it see’s as a threat it will also ask for your permission to do something giving you a clear warning it something maybe dangerous and affect your computer. It will not let network transmissions based on set rules. Hardware and software are the two types of firewalls. Firewalls for hardware can be used as a part of a router and firewalls for software are programs that are used on the computer, like Windows Firewall. Firewalls also help to stop the spread of viruses on the computer.

Passwords

Passwords are a good way to keep your data or information safe, it is important to have a good strong password so people won’t be able to guess it easily. It is good to have a combination of numbers and letters in your password to make it stronger it is also not a good a idea to write your passwords down on your computer as someone could gain access to them also you should check your computer for key loggers which record every key you type.

SSL

SSL stands for secure socket layer, this will provide communications security over the Internet, and SSL encodes the data of network connections above the transport layer and the lower sub-layer of its application layer using a message confirmation code for safety. Websites that use SSL will have a certificate to show that their websites are safe to use. This will make more people want to use the website because they know it’s safe to use.

User Side Factors

Download Speed

If the user doesn’t have a good enough downloading speed, web pages may fail to load all content or won’t load up as quick and things like videos and pictures will take a lot longer to load,

Browser

Some Internet browsers don’t support file types used in websites this causes errors when loading the website using a popular browser may fix this or there maybe be third party software needed like flash player as most videos wont play without it installed

Cache Memory

This helps to load different website pages that are visited more often than others. If the user visits a lot of pages it is a good idea to configure a higher cache memory capacity, which is in the browser settings.

Processor Speed

If the user doesn’t have a very good processor, web pages will take considerably longer to load up and show content due to the amount of calculations made per second. A better processor would make web pages load faster even if they contain images and videos.

Server Side Factors:

Available Bandwidth

The bigger the bandwidth the better as the bandwidth is what allows you to have more viewers looks at the site. If you have a large bandwidth you can have a lot of people watch videos as videos take up a lot of bandwidth. Bandwidth can determine how much you can download at the same time

Having a higher bandwidth you can download more data in the same amount of time. Even if you have a high speed Internet and a low bandwidth it will still be restricted to a slow download speed.

Executions to be performed before Page Load

Before the web page is fully loads different parts of the page must be loaded first. Like the head, this hosts the CSS and JavaScript, and then the body. This is why a web page that loads slowly or has a lot of contents will only display the background and colors at first and it will show the foundations. Then followed by the body, which holds information.

Number of Hits

The number of hits on a web page is basically the number of requests sent by a user's computer to the server hosting the web page. While it does not tell you the exact number of people using the web page and how many people have visited the site this is a good way of keeping track of how your website is doing as the more people use it the slower it will get and if to many people are on the website it will crash

File Types

certain browsers will not be able to show certain file formats, sometimes there are problems with not being able to view images, videos and audio this is due to the user. It depends on the server side factor as the web page creator has to choose what file types they use.

Bitmap is a way in which an image is created its called bitmap is small pixels which go together to form an image many people use this as they can do small details to images such as shading as there is a range of color with it. Saving a bitmap image takes up a lot of space due to the fact it saves each pixel bit by bit. Paint uses bitmap this is why when you enlarge an image in paint it becomes pixilated.

JPEG has an even larger color palette and is better for high colored images. Both JPEG and GIF mean shading can be done to perfection as well as the detail on the image

Vector is much smaller in memory compared to bitmap as it saves images in chunks, it makes images with lines and shapes this makes the image more simple but when it comes to save it doesn't take up much memory. Microsoft word uses vector this is why when you enlarge an image in word it doesn't become pixilated. Vector is often used to create logos, as logos often need to be re-sized

MP3 is a type of music in the way it is stored, its a good one to use because it doesn't take up much space as its compressed and small.

AVI is a type of video. Its a windows based application and it doesn't use up a lot of memory. It's advised to use AVI instead of SWF as it takes up less memory. The fuller the memory the slower the system
