Wireless Communication - IEEE 802.11 / WiFi
Another name for this type of network is wireless fidelity. It is used to provide another method of connection to a LAN network router without the need for wires or any other means of physical connection
Another more technical name for this type of network connection is 802.11. 802.11a this was the first wireless connection that was developed which would transmit data at a maximum speed of 11Mbps. Then the next wireless was called 802.11g within this network the data could be sent at speeds of up to 54Mbps. The latest wireless connection is WiFi which is also called 802.11b this allows data to be sent at speeds up to 125Mbps.
Wireless connection is all about connection a computer with a wireless network card to a LAN, a WAN or the internet directly through a wireless connection. To connect, simply connect the wireless network card and you will be able to connect, some connection need a IP for you to connect successfully.
This is mainly used when cables are not an option or cables and wires could get in the way or cause problems. It is used a lot by business men that carry laptops as they are able to connect at the nearest point where they can get a connection.
IrDA – Infrared
IrDA stands for Infrared Data Association. This type of data transmission uses light waves to transfer data. It is mainly used for connecting the computer to other external devises including printers and now most computers and other external devices now come with IrDA ports. This enables you to transfer data from one device to another without any cables. For example, if both your laptop computer and printer have IrDA ports, you can simply put your computer in front of the printer and output a document, without needing to connect the two with a cable.
The only limitation of using infrared to transfer data is that to use are that the two devices must be within a few feet of each other and there must be a clear line of sight between them.
Bluetooth
Another type of wireless connection is Bluetooth it is also known as IEEE 802.15.1. This is used within personal area networks (PANs), these are mostly used to transmit data from mobile phones to send things such as images, videos and mp3s. this can be done from one mobile phone to another or from the computer to the mobile phone.
LAN
This is also known as a Local Area Network (LAN). This type of network is where there are more than two computers connected in the same building. Although most LAN is connected in the same building, they can be connected to other buildings by using telephone lines and radio waves. When this happens, it is called a WAN (Wide Area Network)
A LAN is made up of personal computers; these are known as nodes in the network. These computers are connected to a server so that whichever computer you are logged onto, you are able to access the data that is on that server. With networks, you are able to share many hardware devices such as printers and internet connections, this saves money.
Access Point
This is sometimes known as a transceiver, it is a station that transmits and receives data. They are able to connect to its users that are on the network and they can also serve as the point of interconnection between the wireless local area network and a fixed wire network. Each access point can provide more than one user within a distinct network area for example, when people move past the range of one access point, they are passed over to the next one.
LASER
This is also known as light amplification by the stimulated emission of radiation. This is a device that makes a light that is on constantly, it not like a normal light bulb though. If it is placed in the same place for a certain amount of time, it is a pure beam which can also be focused to be a single wavelength.
Narrow band radio
A narrow band radio is a small bandwidth which can reach speeds of up to 3 kHz. This is out exceptional to one channel and it can provide a transmission wave for an analogue signal. The analogue signal can be presented from a digital signal where the signal is contained within a voice channel.
Spread spectrum radio
This is where a signal is allowed to be passed over from frequencies to electromagnetic signals; this is done by the spread spectrum radio. Examples of this are wireless internet connection, mobile phones and radios; basically it is anything that uses radio waves.
Point to point and extended LANs with wireless bridges
This is a device that is used to connect more than two networks that are placed differently in different buildings. An example of this is the Cisco Aironet 350 which allows connections of transmission speeds of up to 11mbps, however this does seem slow but it is sending data over distances of 25miles. Now the wireless LAN’s make use of technology known as IEEE 802.11. There are two main kinds of wireless connection; these are 802.11g and 802.11b. 802.11b was the first type of wireless connection; this is however a lot slower than 802.11g. 802.11g is faster as it can reach speeds of up to 54mbps and also includes WI-FI protected access (WPA). The most recent type of wireless connection is called 802.11n; this can reach speeds of up to 100mbits. Most LAN networks are used schools hospitals and any type of business with more than two computers.
Wireless local area networks have wireless bridges; these have ports on them which can connect to more than one local area network. The bridges that are used, what they do is they collect packets that are sent over the network. Until the bridge receives the complete packet, it will not send another one if it has to. Bridges are able to transmit data simultaneously.
Increased availability of mobile computing
Mobile computing is getting more used as technology is developing. Some of the latest mobile technology is wireless internet connection and mobile computing. Mobile computing is not too expensive and is at a reasonable price to purchase, e.g. PDA’s.

Network Communication Continued
IRQ
IRQ stands for Interpret request. It is a device that works within the processor within the computer using input terminals. It is the hardware signal that instigates an interrupt that has an occurred. Within the modern computers today they use plug and play on them where as they used to have to set IRQ on them individually. Also within your computer each device including network interface card, keyboard, and mouse, is assigned an Interrupt Request (IRQ) this is a line that the device uses to alert the microprocessor that data needs to be processed. Each of these devices that are connected to the computer need there own unique IRQ if not the there will be conflicts between the IRQ. IRQ’s are not normally assigned to an NIC but if on the computer you are using an old version of windows, it is best to assign one as this will prevent running into an IRQ conflict.
DMA
DMA stands for Direct Access Memory this is a method of transferring data between two different memory locations within the computer. DMA is used to send the data at high speeds and large amounts of data at once. This is normally used for video displays that contain a lot of moving and changing images and these have to be changed at different frequency times.
In order for a NIC to operate efficiently, it needs to be able to carry out its interface tasks with minimum disruption to the CPU of the computer.
Four methods of NIC to computer data transfer are used
Bus mastering DMA (direct memory access):
•Data enters the NIC from the network.
•The NIC's own CPU stores data in the NIC's RAM.
•NIC's CPU sends data to computer's motherboard when the network transmission is complete.
•The computer's CPU is not interrupted - the NIC's CPU has ultimate responsibility for data transfer.
DMA:
•Data enters the NIC from the network.
•The NIC's CPU interrupts the computer's CPU.
•The computer's CPU stops other tasks and transfers the network data into its RAM.
I/O
I/O stands for Input / Output this is used to describe the entire connection path between the CPU Bus and the disk drive. It also is used to describe the "read" and "write" information sent back and forth between the CPU and the disk drive. This means it describes the method in which the information that is read off and writing on the CD is send back and forth between the disk drive and the CPU
There are four techniques used for transfer of data, the NIC may use one or more of these techniques.
•Polling is where the microprocessor checks the status of the peripheral under program control.
•Programmed I/O is where the microprocessor alerts the designated peripheral by applying its address to the system's address bus.
•Interrupt-driven I/O is where the peripheral alerts the microprocessor that its ready to transfer data.
•DMA is where the intelligent peripheral assumes control of the system bus to access memory directly. This removes load from the CPU but requires a separate processor on the card.
RAM
RAM stands for random access memory. RAM stored data as electrical signals. if the power from the computer is cut off then all unsaved data will be lost. When saving data it can never be stored permanently onto the RAM so therefore this type of memory is known as volatile memory
There are two basic types of RAM:
-dynamic RAM (DRAM)
-static RAM (SRAM)
Memory address register
This is a number that is given to each byte within the memory within the computer that is used within the CPU to track where data and instructions are stored are stored on the ram. Each byte is given a memory address and whether or not it is being used to store data. The computer’s CPU uses the address bus to communicate which memory address it wants to access, and the memory controller reads the address and then puts the data stored in that memory address back onto the address bus for the CPU to use.
Setting protocols
A protocol is a set of rules and instructions which are used to tell the computer what to do and how to communicate with other hardware in the computer. Therefore when there are one or move computers within a system they will exchange many messages to tell each other what they are doing what they are to do. It is a format for which computers understand and know what to do for when they receive and send data. Therefore when there is more than one computer communicating, they will exchange messages There is more than one type of protocol; the most common ones are HTTP and FTP. HTTP is also known as hyper text transfer protocol, this is a server protocol, and this is used for people who wise to gain access to the internet. FTP is also known as File Transfer Protocol, this is when files are sent over a network. There are three protocols that are known as flow control, error control and data compression.
Data bus
A data bus is a physical connection that is used to carry information between the CPU to the other devices within the computer. This bus also carries data that is being processed or used within the system. There is also another bus called the control bus that sends signals that report all of devices within the system.
For example, one line of the bus is used to indicate whether the CPU is currently reading from or writing to main memory.
This uses a collection of wires connecting the CPU with the main memory that that is used to identify certain addresses in the memory.
All buses consist of two parts - an address bus and a data bus. The data bus transfers actual data whereas the address bus transfers information about where the data should go.
OSI Seven Laver Model
1.Application layer
2.Presentation layer
3.Session layer
4.Transport layer
5.Network layer
6.Data link layer
7.Physical Layer
These days when a computer is bought, it is ready made to be able to use on networks. The whole point of standardisation is to make sure they have more open systems, which means users will be able to select from a wider range of manufacturer’s products. The OSI seven layer models for communication protocol identify a hierarchy of seven layers.
1.Application layer
This is the transfer of information between both of the users, applications programs and devices (e.g. writing a letter or sending an email). The applications layer hides the physical network from the user, File transfer, access and management. A gateway can provide a connection between any networks at this level. Think of user view of system. The application layer contains a variety of protocols that are commonly needed. For example, there are hundreds of incompatible terminal types in the world.
2.Presentation layer
Describes the syntax of data being transferred so that different devices, which may be using data in different formats, can communicate with one another. It may also carry out encryption to ensure data security during transmission over vulnerable telecommunication links, The presentation layer also attempts to deal with conversions between terminals that use different line and screen lengths and different character sets, Think of character format.
3.Session layer
Describes the organisation of data sequences larger than the packages handled by lower layers, When a user requests a particular service from the network, the session layer handles the dialogue including the use of passwords and user-ids, It also manages data exchange (i.e., duplex or half duplex), Think of an Internet dialup session.
4.Transport layer
Describes the quality and nature of the data delivery, The transport layer masks out any peculiarities of the network and any undesirable features that may prevent a high quality transmission for the network, It provides the session layer with a reliable message transfer facility that is independent of the underlying network type. Messages are divided into message blocks with error detection and security procedures. Think for routing.
5.Network link layer
Describes the routing of packages of information around the network over various data links and between any two notes in a network (or between networks), Larger message blocks can be subdivided into packages; A router can connect dissimilar networks at this level. Routing software can also carry out accounting functions to enable the network owner to charge users. This is the layer in which the NIC operates under. Think of network packets.
6.Data link layer
Describes the logical organisation of the data bits transmitted on a particular medium. The data link layer handles error detection, error correction, retransmission and synchronisation (which improve the quality of the network), Data is transmitted in frames, and each frame containing one packet, a bridge can connect two similar networks at this level. Think of data transmission.
7.Physical layer
Describes the physical properties of the various communications media (which includes the mechanical properties, electrical properties and the transmission of binary data within the communication channel). Standards are set regarding the mechanical, electrical and procedural aspects of interface devices, For example, standards are set for the number of pins a network connector should have and the function and position of each pin, at this level data is sent as a serial stream of bits - there is no error correction. Think of wiring

Networks Communications
Baseband
This is a type of data transmission. This type of transmission sends both a digital and analogue signal over one single multiplex channel. This means there is one single line or channel that can transfer both analogue and digital signals. Examples of this would be an Ethernet or LAN (local area network). Baseband transmission uses TMD which is a Time division multiplexing, this means it sends bits of data at different times along the full bandwidth.
Broadband
This is a type of data transmission. This is a faster type of data transmission that carry several channels at once as the other types including base band struggle to send one signal at once, broadband can transfer many signals at once over a vast network
Modem
A modem is a device used to convert a digital signal into an analogue so data can be transferred easily. When data is stored within a computer it is stored in a digital form but when it is transferred down a telephone it has to be changed to an analogue signal to go down telephone line. A Modem is a piece of hardware using to pass information from one pc to another using a telephone line. The modem acts like a telephone and allows two computers talk to each other. A modem can transfer data at 30,000 bits per second
Digital Signalling
A digital signal is when binary numbers are transmitted as a signal this signal only works using 2 numbers 0 and 1. Unlike the analogue signal, digital signal switch on and off. This is also known as a pulse wave. This wave can only be positive and negative
Analogue waves
An analogue signal is like a wave that represents the vibrations of the sound. This means that the information can have an unlimited amount of numbers. The analogue signal is an continuous.
This is how it works
From the computer the signal is sent as a digital pulse wave then it is converted into an analogue wave to travel down the phone line then it is converted back to a digital to go back to the receiving computer.
Amplitude modulation
Amplitude modulation
Amplitude modulation is a type of modulation that is used within the radio transmission to send audio sounds and messages For example, radio uses AM to transmit an audible sound of say 400 Hz by varying the amplitude of a radio signal with frequency 100,000 Hz. This is means of loading information onto a carrier wave by modulating its height.
Frequency modulation
Frequency modulation a method of transmitting information on radio waves by encoding the information as a change in frequency or number of waves per second. This is also used in radio transmission (FM).
The advantages and disadvantages of using baseband transmission
Advantages
Cheap to setup
Fast data transfer
Disadvantages
Can only transmit over a small area
The advantages and disadvantages of using broadband transmission
Advantages
Can transmit data over a large area
Fast to transfer the data
Disadvantages
Can be more expensive
Unicast
Unicast is a type of communication within a network that is sent by a single sender and is receive by only one single receiver. An simple example of this is a simple email from one person to another
Multicast
This is another way of communicating over the network. Where as the unicast was sending a message from a single sender to a single receiver, multicast is sending a message to a specific group. So it is sending a message from a single sender to a group of receivers. An example of this is sending an e-mail message to a mailing list Teleconferencing and videoconferencing also use multicasting, but require more robust and technical networks.
Broadcast
This is another type communication over a network. Broadcast simply sends a message to all of the systems within the network. Whereas the other two types of communication sends the message to specific recipients where are this one sends it to all of the systems within the network. Broadcasting is a useful feature in e-mail systems.

leona lewis music video
i no i no its leaon lewis music video but i like it and now the song has really grown on me and now i luv it as much as the video. i was attracted to the video from the first time i saw it, i dont no y i just think its well produced and you can defo telll it was produced in america theres just a certain cerfistication about it that shows me that its been done by someone who really knows what they are talking about. the shots wen shes in the corridor in the black dress are really nice shots and it looks like the bit in the well known madonna video. this was done more than 10 years ago and there doing it again with a modern twist to bring it up to date. i aslo like the way they have used the different apartments to show the differnt issues within a relationship. this is very cleverly thought out. this also reminds me of the 'Say My Name' video by Destinys Child the way they show each room with a different colour and the shots got from room to room showing different things.
Lambini dancin advert!!!
well heres the thing i was actually doing some work (reseach some may call it) and i found this then adrian kindly informed me that people actually do this dance in the clubs in europe its like a huge thing like people have like competitions to see who can do it the best!!! i just thought it was just a dance that was chorographed for the advert. imagine trying to be that co-odinated when ur drunk or in my case just at all!!

Communis Research
After i had decided to used communis for my presentation and got some information from liam i was even more interested in what they do so i found out who there clients were then looked at some of there websites

The Phone Call
So as part of first SPP2 task i have to produce a presentation on someone that inspires us to choose the pathway that we have so i choose to produce a presentation on the company called communis that deal with accessibility. i knew of this company though a lecture on accessibility we had last year so already kinda knew how to go about getting in to contact with them.
my first port of call was Adrian as i knew had a lot to do with this field so i emailed him asking if who i was to get into contact with and how. he was really help full and replied really fast with exactly the right information i needed. he gave me the guys name and how to get into contact with him and even emailed contacted him first and mentioned me to him. Adrian gave me a choice i could either email Liam through him or call him myself. i thought bout this and thought that it would look more professional if i called them myself as then he would know that i am serious bout this.
so i did and this is wot i got from it
what is your roll within the company
"I'm the managing director"
how did u get to where you are now
"Well i started before there was any such thing as the Internet in spring 1995 and started teaching myself when it was all new and exciting"
"i was unable to use a mouse"
"It was then called Design for all"
what made you want to do what you do
it wasn't just the fact that i couldn't use a mouse it was that i wanted to produce good websites and if you create a good website it will be accessible
he kinda said the same but made it sound different as the last question
where do u think the future is within this area
how would you advise us students and graduates to get into accessibility
hmm i think its skipped a generation as we have all been self taught about the Internet so some students come to us having a first class degree and no experience and it means nothing to us and it would cost too much to train them.
wow i was so inspired to learn that he as some kind of disablity himself so he knows exactly what its like hes not just some person who thinks he knows what hes talking about when it comes to restrictions through disability. also he was self taught means that his knowledge is very thorow.
although he did scare me when he started saying that students think that there degrees thinking there good but there's no way
then he said if u bring me a website that works on 5 different phones and different screen sizes then all give you a chance.
so id better get working then!!!!
my first port of call was Adrian as i knew had a lot to do with this field so i emailed him asking if who i was to get into contact with and how. he was really help full and replied really fast with exactly the right information i needed. he gave me the guys name and how to get into contact with him and even emailed contacted him first and mentioned me to him. Adrian gave me a choice i could either email Liam through him or call him myself. i thought bout this and thought that it would look more professional if i called them myself as then he would know that i am serious bout this.
so i did and this is wot i got from it
what is your roll within the company
"I'm the managing director"
how did u get to where you are now
"Well i started before there was any such thing as the Internet in spring 1995 and started teaching myself when it was all new and exciting"
"i was unable to use a mouse"
"It was then called Design for all"
what made you want to do what you do
it wasn't just the fact that i couldn't use a mouse it was that i wanted to produce good websites and if you create a good website it will be accessible
he kinda said the same but made it sound different as the last question
where do u think the future is within this area
how would you advise us students and graduates to get into accessibility

SPP2 Task 1
Look at a Pathway practitioner and prepare a presentation for next week. An analysis of this person/people should be posted on your journal. Include links to where we can see their work/or discussion of their work.
At first this task scared me to death and i thought there is no way i can get in touch with a professional web designer!!! I mean people like that haven't got time to chat to students like us. so i sat down and thought right why do i want to be a web designer then i thought Money !!!! then i thought like any girl would Shoes and Handbags so then i start thinking bout the fashion mags then i thought no way.
so then i thought what bout the other thing in my life that i feel strongly bout which is accessibility because having a disability myself i feel strongly that people with disabilities have enough to deal with in there lives without having something as trivia as the Internet proving more difficult to deal with than it should be. i also think that it is where the future is when it concerns the web because nowadays more and more people are using mobile Internet on things such as PDAs and mobile phones
right that's it I've finished my rant now so i decided on accessibility so then find out some information then i remembered that we had a guest lecturer that taught us about accessibility so i thought if i could get in touch with him he could give me the information i required for this task.

Welcome Back!!!
Wow here we are made it through to the second year! So welcome back and this year I'm gonna be blog crazy. OK I'm gonna be honest here i hated doing my blog last year and have never really got on with it. i think this is because i put too much pressure on myself to do it right and be all professional and try to show off. therefore i became terrified of it totally and just refused to do it at all. This got me into a little bit of a predicament as it got to the end of last term and i had done about 5 blogs and ended up doing a hard core week of blogging which was probably the most boring week of my life and to make matters worse i had no one to blame but myself!
so this year I've chose a different approach I'm gonna put whatever i want in my blog now what i like, what i don't like, what i want to do and wot I've done that i think is good. even though this is probably wot they've bin wanting me to do all the time i think i just put far too much pressure on myself to do it rite that it was wrong. so this is fresh blog and a fresh start for me and the blog and as jools so rightly said today i have to reflect on my mistakes and learn from them.

Identities-Finished Product
I think the finish product is well researched and well put together however I think I still need to look at the finer details within my project and there could be some slight improvements such as testing and checking everything works how it should and everything is saved in the rite format. The things I like about the package are the flyers sunglasses and web banners.
I think there are good points and bad points at each stage of my project but overall I think it needs a few minor improvements.
I think overall the research section was a very strong well planned part of my project and I think I used the criticism, I receive very well and there for it was very useful and effective within the rest of my project. I also think I used the accessibility when creating my website and other parts of my project and I think it was a major factor for me within this project. So overall I think this was a very good part of the project.
I think the working methods of my project were good as the way I used the poster not only for my research but, also as a basis for the whole project I think that was a very effective. I also think that the planning involved with getting my flyers and posters and post cards printed was also very effective. However I think that my testing and checking of my website could have be been improved greatly.
The finished product in conclusion this part of the project was good if it on my computer but as I didn’t test it on other machines so in the presentation the finish product was not as good as I’d have hoped.
Overall I think the project itself was good and it would have been better if I had tested and checked more accurately.

Research-Platform
Platform is a third of the Trent Media organisation. Like the other aspects of Trent media Platform is all about the students. This time I knew of Platform but again I didn’t know it was a part of the Trent Media. I knew it’s existed as I saw it around the halls and the union and the halls and other parts of uni but I had never read t or took much notice of it before. So again I looked into what Platform was involved in and what it actually did. I soon realised again that it was all to do with the students. but they don’t seem to be reading it or getting involved. This could have been the case for a number of reasons, including there advertising structure was not very strong and there wasn’t a lot of info about the magazine out there and within there logos there wasn’t anything to tell people that the three sections within Trent media were connected in anyway for example I knew that want Trent media was but I didn’t no about Trent TV. This is when I found out more about what they did, wrote about and were involved with. I also looked at the material such as there logo and website etc.
After looking at the current material I thought that out of the three logos within Trent media I thought this was the most appropriate logo that were for the product that it was used for so I thought that was good but other than that it was more or less the same as the other 2 in the colours were not very eye catching and they didn’t have much continuity within them all
So after I had looked at all the information I thought about some of the basic ideas that were going around in my head
I cant change the name so it could be something to do with writing and reading
Something to do with platform a stage
Students
Continuity with the Trent media logo
More colour
Something that will attract people of my age
Online
Easy to access to watch online maybe a button on desktop
I also looked at magazines that are out there and local magazines and newspapers

Interactive Narrative
Having scrapped my first few ideas about the interactive narrative i decided to keep it simple and create an interactive narrative about what would happen if you stay in or go out. this mean you would have different outcomes with whatever u click on so for example if u click on the sparkly top then u would go out of if u clicked on magazines or DVDs then u would stay in.
So the first thing i did was to take the photos so i took photos of everything i could think of that you would do if u stayed in and everything if you went out. then i took the images and put them on different pages within deamweaver and linked them together using javascript to make a interactive narrative. the most difficult thing to do within this task was making sure the links linked the correct pages together but other than that it was pretty simple as i had already had a little experience with java script before.

Design Board Presentation
During the ident project i had to create a design board to present my ideas for this project to the tutor and other students
Overall i think it went well and i was pleased but i was given the feedback that i needed to do more research on what people like not just go on wot i liked which was a very fair point and therefore led me to create another questionnaire and do more research so overall it was very successful and useful within my project.

Identities-Working Method
within the identity package that i created i created a number of different advertising things in order to boost awareness these included:
Poster
Flyer
Postcard
Web banners x2
Website
Sunglasses
Bag
So I started by designing my poster first then I could get an idea for the whole brand I also used this as part of my sample pieces during the research process. So I used this to base the whole package on as I new that the students liked it. I used this to design my flyers and postcards. Evaluating this method of designing it was very useful to me as I designed something very simple such as a poster and used it then to base the rest of the package around. This also helped me keep the continuity within my package.
So after I had done the simple parts of my package I then went on to do the more complex things within this project such as my website and web banner. I started by doing my web banners first because I had a very good idea of what I wanted to do with them as I had just designed my flyers and postcards so I had lots of ideas based on them. Evaluating this process I think this was the simplest but most effective part of the project because the way I managed the project this part of the project was very effective as I had lots of ideas from the flyers, posters and other parts of my package. I also made my web banners very simple and effective as I think it gives more of a statement when on another website.
So the last thing of my package I had to design was my website this was the most difficult and time consuming part of my package. I again based it on the rest of the package for example the colour scheme etc. I started by creating the index page as a base then worked out from there. Evaluating this method it wasn’t a very good method of designing this part of the project as I kept adding pages as a result of working in this way. I started off only thinking I needed 6 or 7 pages and ended up having 15 pages and therefore a lot more last minute work.
Also going back to my research of accessibility I found that when people are using screen readers they need to have very simple websites and all the buttons and things that you add to your web site and also you need to be very clear of what you label and name some of the objects within your site so they can be read by the screen reader then therefore give people with sight difficulties full understanding of what is on your website. So therefore I made sure when creating my website that every object that I added was clearly labelled and that my website was kept very simple. This was a lot more work at the time but I think it is worth it to make it easier with difficulties and disabilities.
Also due to my research I created a CSS style sheet that I could put into my website that would get rid of the colours that are not accessible for people with sight difficulties and replace them with colours that people with these issues would be able to view easily. For me this was a difficult task but I feel is it worth it to enable everyone to view my website. Again I think that I think more web designers should think of these issues when creating websites for major companies.
I think my project was managed well. I did a lot of research early on in the project which meant that I could make informed decisions about the rest of the project so that very useful and effective within the rest of my project. I also insured that things such as printing and other factors within my project were done early to avoid the rush on the day of the deadline. However the last part of my of my project was the website deign and that was not planned very well as I kept adding pages within my website which then meant I was behind schedule. I think was one of my major let downs within this project. Also another thing that let my project down was the fact that because I was behind schedule I could not test my project as well as I had hoped this was a major factor as this lead to my CSS and some other issues not working correctly in time for the last presentation I am working on them all and testing them thoroughly to ensure everything is done correctly.
I think the finish product is well researched and well put together however I think I still need to look at the finer details within my project and there could be some slight improvements such as testing and checking everything works how it should and everything is saved in the rite format.

External Work
within this year i have tried to push myself to do some external work as i think it is important to build my CV and learn new skills and maybe even earn some money and at the moment I'm doing things that i really enjoy so therefore it is easy for me to work hard at this and do these things in my spare time.
at the moment i have a few projects on the go all for friends and family. i have decided to do this because i think it is a really good way of learning by actually doing that tasks. I'm going them for my friends and family as it gives me a time limited and i can lean lots of skills like working with a client and time management
also at college i built and created an e-commerce website it was really good and contained a bit of everything from css and java script to flash and action script i was very proud of it

Flash
Within the website that i created within the ident package that i created for trent media i decided that i wanted to put some flash animation on it to make it more interesting and eye catching for the audience .
so i had the idea of makin all the images move or twirl in some way then for this i made the decision that i wanted all the image to roate showing them all one after the other so it would start with the trent media man then going on to platform then trent tv then fly.
so after i decided what i wanted to do then i went on to try and find out how to impliment it so emailed adrian to see if he could help me although i already had some idea of how to do it and how i wanted it to look. i just kinda didnt have the memory or the confidence to just go ahead and it myself.
I arranged to meet adrian one afternoon and he started everything including lots of complex ways of doing apart from the way that i had in mind then we tryed the way i kinda remebered which was to make the image smaller and smaller and doint this gave the illousion that they were twirlin around so he showed me how to do it with one of the images then i had to do it with the other 4 the hardest bit of doin this was making one image disappear and a new image appear in its place.
