This image above is an Intranet Diagram which shows a client using the firewall to send certain information across the internet to the server/receiver. It also incorporates the VPN , the Virtual Private Network to insure privacy of the information when sending it across the internet to the server. The intranet diagram uses the same networking systems as the extranet network.

The image above displays an Extranet Diagram which shows the connection with the client/server and 2 firms using the internet to be able to transport different pieces of information. They transport the information using a VPN, a Virtual Private Network which ensures the privacy of the information being sent across the internet. The Firewall displayed above is like a "gatekeeper" which allows security and authenticates certain users to access the information.

B2C Critique Your Competitor’s E-Commerce Website 5.1

The website that I chose to evaluate was www.ikea.com. Ikea is a Click-and Mortar B2C. This is a website that advertises furniture for different rooms in the house. For example, a kitchen, living room, family room, and even a child's room. The different rules that this website uses all 6 of the listed rules. It offers something unique, its aesthetically pleasing, its easy to use, it also motivates people to visit, it advertises their presence on the web, and a customer can learn from the website. I would rate this website a 4 out of 5. I would give the website this rating because it is an appealing website that would make a customer like me to come back and purchase. When you search for Ikea on a search engine such as google, you would find that the website shows up on the list of results.

Entity Relationship Diagram 4.4















 The diagram above shows an example of an Entity Relationship Diagram. The first entity describes the specifics of the invoice. In an invoice it has different records that contains the customers information. Each record contains attributes that describes what the customer purchases, or just basic information about that customer. The customers information is usually entered into an database table holding their data. The diagram above shows the relationship between the information on the invoice, and the information of the customer and the information and description of the product that the customer purchases.

Packet Switching Technology 4.3











The diagram above is a Packet Switching image that show how information gets broken up into pieces and sent by the client/server through the router. It displays concurrent data, which the job of sending the message and correcting it happens simultaneously. For the information to be sent correctly and on time, Packet Switching Technology is used. The message gets broken up into packages and gets put into the hands of TCP and IP. The IP and TCP have different roles regarding getting the information sent properly. The IP data-gram depends on the IP address, the address assigned to the computers and routers, otherwise the information would get lost. TCP helps the IP deliver the packets.
