The basic networking components required for functioning of our website are categorized in 3 types:
-Access Devices
-Networking devices for data forwarding
-Information servers

Access devices
A user, be it the merchant or the shopper needs a device in order to access the website on a browser. The devices are a desktop/laptop computer, a mobile phone or a tablet PC. With a browser installed on the access device, the users will be able to access the website.

Networking Devices
Networking devices are used in order to connect to the Internet and enable the flow and exchange of data. The components involved in this section are Modem (Wired or Wireless), Routers, switches, Hubs, ISPs etc.

Information Servers
Server used to manage save and …show more content…
Gateways
Anything that operates above layer 3, but still is considered to be part of the networking infrastructure, is a gateway. Gateways can have very different tasks, they can transfer data between different networking architectures, or they can implement application-specific functionality that requires knowledge of particular application-level protocols. A typical example for a gateway is a Wireless Application Protocol (WAP) gateway, that connects the Internet and a mobile phone network (such as a GSM network) and enables mobile phone users to retrieve Web pages with their mobile devices.

Factors involved in selecting a Network Architecture:

Network Requirements
A merchant must have a presence on the Internet so that a client from anywhere on the Internet can interact with the electronic shop set-up by the merchant. The merchant also needs to interact with other third-party companies through the Internet for order fulfillment. This sets up a multi-tier architecture as illustrated in Fig. 1 …show more content…
It holds information of the electronic merchandise and is accessed concurrently by many users over the Internet. Thus a network database is essential to develop a true e-commerce application.

A network database has a client portion and a server portion. The server portion is installed in a computer that runs a server-side operating system such as the Windows NT server.
The client portion is installed in one or more computers in the network running a client operating The server contains the actual database and database-management tools.

The client is used for operating and managing the database system from a remote computer within a local network.
Microsoft SQL Server is a popular network database, because most networked PCs run on the Windows operating system. The graphical user environment of the SQL Server is very simple to use. The SQL server also comes free with the Windows NT operating system and a few other Microsoft software bundles. The security of the SQL server is integrated with the security of the Windows NT operating system. It allows a network administrator to easily map a user’s database access permission to that of the network

P.2 Models: Open System Intercorrection (OSI) OSI (Open Systems Interconnection) is reference model for how applications can communicate over a network. A reference model is a conceptual framework for understanding relationships. The purpose of the OSI reference model is to guide vendors and developers so the digital communication products and software programs they create will interoperate, and to facilitate clear comparisons among communications tools. TCP/IP model TCP/IP stands for Transmission…

consists of hosts connected to networks that are in turn interconnected via gateways. The networks may be either Local Area Networks (LAN) or Wide Area Networks (WAN). Within a business organization at a single location, the computer network is usually LAN. When the business organization needs to communicate with other business or individuals at a different location, a WAN network is created to connect the different sites together. These different types of networks are often connected by using TCP/IP…

protocols used for LAN and WAN networks. I will also discuss the hardware components used and the functionality of them. Some of the protocols I will include in my report are Ethernet and TCP/IP. I will also detail other protocols and the functionality of them. I will show the link the protocols I have between the OSI model and the layer they relate too. The end device is how a user makes a connection to the network. Using things like a laptop or PC with a network interface card establishes a connection…

Task I involved the setup of the network. Kyle, Casey, and Bernadette met in lab to work on this task. It was a simple setup for firewall E so that outside computers cannot access any internal computers and services. This involved setting up Network E such that all service packets were dropped coming from outside IP’s that were trying to access the internal network. Once Task I was done, everyone worked on Task II, which involved cracking the WEP and obtaining the key. This task took a few attempts…
