Web Server: A webserver is a Hardware device used to host an eCommerce website. The server supports the entire content of the website such as HTML files, Data bases and Image Files. Web Servers will run on operating systems such as Windows or Linux and will use web server software to manage access requests to the website. Webservers are similar to PC’s however they have faster processors and more memory making it much more powerful.Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and determining whether they should be allowed through or not, based on a rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e. g. , the Internet) that is not assumed to be secure and trusted. Software Browsers: When you design an eCommerce solution it is important to consider how the site is seen on the web.
When customers access an online shop they will need to use a web browser to load the website. A browser is a software application on a machine that allows someone to access the internet. When a website is loaded in a browser the html code, css, image and information that is stored in a database connected to the website are rendered together to make the site appear in the browser window. When developing an eCommerce site it is important to test that the site appears correctly in all of the main browsers that people use to access the internet such as, Internet Explorer, Mozilla Firefox, Google Chrome and Safari.

This skin can then be exported into a html and css combination that is used as the basis for the developing site. Server Software: Web servers need to run software that manages access attempts to a website.
When a user tries to access a website the web server software processes the access request and serves up the correct files that have been requested from the client’s machine. Examples include Windows IIS (internet information services) which runs on windows based web servers and Apache which runs on Linux based web servers. Server Software runs in the background and works over a network to allow a browser stored on a client machine to access the files that make up an eCommerce site. Database System: A database system is an important part of an eCommerce website.
The database is used to store information about the products for sale on the site. The database will hold information such as store pricing, descriptions, images and other details. In addition to this the customers details are also stored such as what they ordered, payment details, shipping details, phone numbers, emails and lots more. Staff who are responsible for the delivery of items will use the database that is connected to the eCommerce site to ensure all the correct products are sent to the correct customer.

TCP/IP is a complex technology and normally and eCommerce site developer does not have to have in depth knowledge of the protocols but should understand that they exist. Ports: Ports on different devices allow them to connect to other devices stored on the internet.
Ports allow a device with one IP address to access another device with a different unique IP address. A device will normally have more than one port, for example when one user wants to send an email to another they will allow access through port 25 as this is normally reserved for email. When a shopper on a client machine wants to access an eCommerce website they will connect IP addresses from their machine to the web server that stores the eCommerce site over port 80. Other Protocols: FTP (File Transfer Protocol) is the set of rules used to communicate information between two devices running on a TCP/IP based network.
If the customer online was to request a receipt this would be sent to them using FTP.
