Unit 28 - D2
Possible Improvments to My Site
Accessibility - The website is very easy to access, the links are in obvious places and are large enough to be noticed, allowing people to get around the site with ease.
Ease of Use - Although the site is very easy to use, certain areas could be changed to improve the site. For example, the 'buttons' to reach other pages are currently just hyperlinked text, it would be better if they were proper buttons, as this would make their purpose more obvious.
Functionality - The website functions well, but it is very simplistic, it could be improved by adding more text or pictures related to the film club to make the site more appealing.
User Environments, Links, Navigation - The only links on the site are the hyperlinks used for navigation, as mentioned earlier, these could be improved by making them look more professional.
Content - The site does contain trailers from films with an age rating of 12 and 15, this may be inappropriate for some users and could be solved by changing the films on offer to suit a younger audience. The site could be improved with the addition of pictures as there is currently a lot of empty space on some of the pages.
Check against user requirements - Currently, there is no system in place that checks that the user is old enough to join the film club, the site could be improved by adding coding that will prevent people below or above a certain age threshold from joining.

Unit 28 - D1
TCP/IP protocols map to four layers. These four layers are; application, transport, internet and network interface. Each layer in the model links to one or more layers of the seven layer open systems interconnection model. The seven layers are the; application layer, presentation layer, session layer, transport layer, network layer, data-link layer and physical layer.
Internet Layer - This is responsible for addressing, packaging and routing functions. The protocols for the Internet layer are IP, ARP, ICMP and IGMP.
The Internet Protocol (IP) - This is the routable protocol responsible for IP addressing, routing and the breaking up and reassembly of packets.
The Address Resolution Protocol (ARP) - This is the resolution of the internet layer address to the network interface layer address such as a hardware address.
The Internet Control Message Protocol (ICMP) - This provides problem solves and reporting errors due to the unsuccessful delivery of IP packets.
The Internet Group Management Protocol (IGMP) - This is for the management of IP multicast groups.
Transport Layer
This provides the application layer with session and datagram communication services. The protocols of the transport layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
TCP
This provides a connection oriented and reliable communications service. The sequencing and acknowledgment of packets sent, and the recovery of packets lost during transmission.
UDP
This provides many connectionless and unreliable communications service. UDP is used when only small amounts of data are transferred. When the overhead of establishing a TCP connection is not wanted or when the upper layer protocols provide good delivery.
Application Layer
This gives applications the ability to access other layers and defines the protocols that applications use to exchange data. There are many application layer protocols and new protocols are always being created. The most popular application layer protocols are those used for exchanging user information. These are HTTP, FTP and SMPT.
The Hypertext Transfer Protocol (HTTP)
This is used to transfer files that make web pages for the internet.
The File Transfer Protocol (FTP)
This is used for the interactive file transfer.
The Simple Mail Transfer Protocol (SMPT)
This is used so the transfer of mail messages and attachments work.

Unit 28 - M2
Navigation
I used hyperlinks to allow users to navigate around my site, I hyperlinked certain text so that when it was clicked it would take the user to another page on the site.
HTML
I used HTML coding when creating my website, I used it when copying the embed codes for YouTube videos and using the code feature of Dreamweaver to add these videos to my website so that users are able to see the trailers for the films on offer.
Audio and Visual Elements
The film trailers I embedded from YouTube are the only audio elements of the website, these are also visual elements. Another visual element is the logo that I created in illustrator, this is used on every page of the website.
Hierarchy
This separates the page in the order of importance; it is done through the size, colour, shape or font.
