My website can be improved in a few ways. First of all, I could put more information in for people so it would look clearer and more denser and easier for people to understand. I could also make the hyperlinks bigger and a brighter colour so that people would see the links straight away and it will be easier to access different pages. On my trailers page, I could also add more trailers for people to watch. In terms of a better looking website, I could improve my films and payments page by making the pictures of films bigger for people to exactly see the name of the movie and other details. I can generally make the font size bigger so that if people have trouble seeing, they will see clearly the information that has been put in there. For my reviews page, I could again make the picture of a movie bigger and also the text box in which people would be writing the review.Another improvement that can b made is that I can link my reviews page to a database so that people can leave comments and other people could see the comments about the films. I could make the 'movies' page better by adding a button which will allow me to scroll to see more movies, rather than having 8 movies on the page that people can see. Also, on the reviews page, I could add another button or a drop-down so that people can easily click on the movie they want to review. Generally my website hasn't got a lot to improve but the tiny little details so that it would be suitable and easy-accessible for every person.

At first, my website had a white background therefore when I viewed it in Explorer, it didn't quite blend in. I have changed the general page background to black so it could fit in and blend in with the colours, making it look as an actual website.
The first screenshot shows the website without the added images on the sides and it made the website look boring and too dull. Therefore I have added the images of characters from the movie and placed them on either side to make the website look more fun and obvious that this website is about films.

To create my interactive website, I have used a lot of things to help me build it to a high standard. At first, I created the layout in PowerPoint that I was planning to use in Dreamweaver. With that I have first mixed up the colours to create my own, original banner and then I have found some pictures of Iron Man and Thor on the Internet because that way, it would be obvious that my website is to do with films. I have also used fonts in PowerPoint to edit the information and make my website look more creative, since Dreamweaver doesn't provide you with many different fonts that can be fun to look at. Then, I have saved all the images and my layout as PNG so that I could easily put them in Dreamweaver. I have also saved my buttons as the same PNG file so that then all I had to do is make them work and link up to pages when it comes to making an actual website.
When it came to Dreamweaver, I first had to define my page before creating anything else. Then, I have created a table for my layout and I had to merge some columns together so that my banner would fit normally. Then I have added all my images and began to create the website. To make my pages link, I have created a small table then wrote all those page names in, then clicked on one of the names and at the bottom of the page it said 'link' so I had to click on the file, go to my pages folder and click the page on which I want this page to be linked to. When my main layout was done, I had to save it 5 times so it would be 5 pages. Then I inserted all the images and typed in the information. To put a trailer in, I have used the embedded code from a YouTube video and then I placed the code in the code section on Dreamweaver. I have also placed another code in the code section of a PayPal button. Then I could view my website in Internet Explorer and saw that everything I did worked normally.

This is how I mixed up the colours to create my own banner.
This is how my layout for all 5 pages looked.
This is how I linked my buttons.
This was the embedded code I used for my trailer.
This is how I defined my page.
This is how I saw all my files here.
This is the code for the review PayPal button.
This is the table that I created.

SECURITY RISKS
Viruses - Viruses are easily picked up and can spread vastly causing significant damage, computer viruses are able to copy themselves and infect your computer. If someone owns a website and it becomes infected with a virus, it won't only potentially affect the owner's computer and website but will more than likely spread to other users when they enter their website, so the virus could infect millions of people at one time. The website can be affected by crashing or becoming unresponsive.
Hacking - Hacking is referred to as the re-programming of a system to function in ways not authorized by the owner, administrator or designer. It is also referred to as the modification of a program or device to give the user access to features that were previously unavailable. If someone's website was to be hacked, it may cause massive problems such as the hacker gaining access to all the owner's customers details, they are also able to change the prices of products and all the other little details. They can change almost everything, so this is potentially dangerous for a website.
ID theft - ID theft is a form of fraud which involves using another person's identity, typically in order to access resources, to claim benefits and make money. This is particularly dangerous on the internet as many people share their details, thinking the internet is secure and others won't be able to access it, but it's very easy to retrieve information from the web. ID theft is most easily done through the internet, once you know how to hack into someone's website, you're able to retrieve a lot of information about them.
PROTECTION MECHANISMS
Firewall - Firewall is part of a network that is designed to block unauthorized access. It is a device that is used to permit or deny network transmissions based on a set of rules. When owning a web company or any other business, it is very important to have a hardware firewall (this may be a router) as well as software firewall because its important that someone has those when running a network of computers as it will help that person to prevent the spread of virus throughout his network. So if one computer is to become infected it won't spread to the rest.
SSL (Secure Socket Layer) - The secure socket layer provides communications security over the internet. SSL encrypts sections of network connections above the transport layer using a keyed message authentication code for message reliability. For websites its very important to have a certificate showing you a secure website as customers are more likely to visit you and will at ease giving out their details. There is a process of what happens when a web browser connects to a secure website.
This is a screenshot that the web owners would have in each and every site. Everyone would have Terms and Conditions about the customer and the product that they're about to apply for or buy. The user/customer is meant to accept/agree the terms and conditions before applying or going any further with their registration.

TCP/IP protocols map to a four layer conceptual model. The four layers of the model are: Application, Transport, Internet and Network Interface. Each layer in the model corresponds to one or more layers of the seven layer Open Systems Interconnection (OSI) model; (application layer, presentation layer, session layer, transport layer, network layer, data-link layer and physical layer).
Internet Layer- The Internet layes is responsible for addressing, packaging and routing functions. The core protocols of the Internet layer are IP, ARP, ICMP and IGMP.
The Internet Protocol (IP) is a routable protocol responsible for IP addressing, routing and the fragmentation and reassembly of packets.
The Address Resolution Protocol (ARP) is responsible for the resolution of the Internet layer address to the Network Interface layer address such as a hardware address.
The Internet Control Message Protocol (ICMP) is responsible for providing diagnostic functions and reporting errors due to the unsuccessful delivery of IP packets.
The Internet Group Management Protocol (IGMP) is responsible for the management of IP multicast groups.
Transport Layer - The Transport layer is responsible for providing the Application layer with session and datagram communication services. The core protocols of the Transport layer are Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).
TCP provides a one-to-one, connection-oriented, reliable communcations service. TCP is responsible for the establishment of a TCP connection, the sequencing and acknowledgment of packets sent, and the recovery of packets lost during transmission.
UDP provides a one-to-one or one-to-many, connectionless, unreliable communications service. UDP is used when the amount of data to be transferred is small (such as the data that would fit into a single packet), when the overhead of establishing a TCP connection is not desired or when the applications or upper layer protocols provide reliable delivery.
Application Layer- The Application layer provides applications the ability to access the services of the other layers and defines the protocols that applications use to exchange data. There are many Application layer protocols and new protocols are always being developed. The most widely-known Application layer protocols are those used for the exchange of user information:
The Hypertext Transfer Protocol (HTTP) is used to transfer files that make up the Web pages of the World Wide Web.
The File Transfer Protocol (FTP) is used to the interactive file transfer.
The Simple Mail Transfer Protocol (SMPT) is used for the transfer of mail messages and attachments.
Additionally, the following Application layer protocls help facilitate the use and management of TCP/IP networks:
The Domain Name System (DNS) is used to resolve a host name to an IP address.
The Routing Information Protocol (RIP) is a routing protocol that routers use to exchange routing information on an IP internetwork.
The Simple Network Management Protocol (SNMP) is used between a network management console and network devices (routers, bridges, intelligent hubs) to collect and exchange network management information.
Internet Layer- The Internet layes is responsible for addressing, packaging and routing functions. The core protocols of the Internet layer are IP, ARP, ICMP and IGMP.
The Internet Protocol (IP) is a routable protocol responsible for IP addressing, routing and the fragmentation and reassembly of packets.
