Web Application Development

The first versions of WWW ((what most people call “The Web”))) provide means for people around the world to exchange information between, to work together, to communicate, and to share documentation more efficiently. Tim Berners-Lee wrote the first browser (called WWW browser) and Web server in March 1991, allowing hypertext documents to be stored, fetched, and viewed. The Web can be seen as a tremendous document store where these documents (web pages) can be fetched by typing their address into a web browser. To do that, two im- portant techniques have been developed. First, a language called Hypertext Markup Languag (HTML) tells the computers how to display documents which contain texts, photos, sounds, visuals (video), and animation, interactive

Web technologies are one of the last components to an IT system. It connects the company to the World Wide Web. A company may utilize it to service clients where they use the interface or it could be used by the company to input client information. Web technology can be used as a way of staying connected with multiple people at once. Web technology also can help a company save, transfer, and download information that has been saved into a cloud.

A web server is a PC that opens pages on a browser on request. It sends the web address of the page that has been requested to the web browser. They have an IP address and possibly domains and are essential for an ecommerce because ecommerce is online and a web server is what you need to surf the web.

Web hosting services – this is where a user will buy a certain amount of storage space on a company’s network, which will then be visible to the public through a IP address, and store their website files so a third user can visit the website. This allows users to view the website by downloading packets of information.

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.

This statement indicates that there should be careful and deliberate choices when choosing a web server. Many different operating systems are available to use as a webserver. One of the most popular is Linux. Linux and UNIX are very reliable when it comes to security. Versions of Linux include Red Hat, Ubuntu, CentOS and Fedora. The advantages of Linux based web servers are easily modified, stable, and secure. Red Hat Linux is currently the best with regards to performance at large scale. UNIX is also a viable option when looking for an operating system. Comparable to Linux, it’s very reliable, easy to customize and secure as well. However, its hardware requirements and cost make it difficult to make it into a web server. Microsoft Windows Server operating systems are a very popular method for an operating system. Microsoft offers different versions of its server software including the 2003, 2008 and 2012 editions. The Microsoft platform is a great choice because most of the online applications are adaptable to use on their OS. Support for Microsoft is readily available as well, making it even harder to choose another OS. The only down sides are that it is not as secure as the previously mentioned Linux platform and because Microsoft uses licensing for their OS, it can be pricey to add to use for the system.

“The mail server is a server that stores and manages electronic messages (email) among users. If you are using Microsoft email products, you will be using Microsoft Exchange to act as your mail server, and you would most likely access the email using Microsoft Outlook or a web browser” (MOAC, 2011) . Having web services is ideal, as well. “Using a web server to provide web services means that users can access web pages using their browsers. These web services may be used to do research, provide leads for sales, allow customers to purchase goods and services, and provide customer support over the Internet. Web services may also be used to provide an easy method to access databases, run reports, track sales leads, provide customer support, and even help you with payroll and human resources” (MOAC,

Server: This is a computer that is designed to carry out specific functions at the request of other computers they’re connected to a network and direct the information stored on the network to clients, for example a web server will run software that receives requests from clients and then processes the request and delivers an output using HTML.

Apache is the most common web server used. The functionality of the server can be expanded with modules if necessary, and it is easier to install and deploy servers that require more features.

Web application is the communication between client and server using HTTP protocol. Where the server is responsible for serving web pages. Client which is web browser, request web page from the server, receive the server response and display to the user. The user uses the client (web browser) to display the web pages, watch videos online etc. The client side and server side programming refers to the programming which runs at the specific side, the server’s or the client’s.

Because Web servers are one of the few system components on a target network that typically communicates with third parties, they are frequently the targets of malicious attacks by intruders. Intruders can easily launch automated attacks against thousands of systems simultaneously to identify the relatively few vulnerable systems.

A web hosting company allows business big and small, also individuals to make their websites accessible on the internet over the WWW (World Wide Web) hosting companies provide space on a server, this can be rented space or the actual server itself can be owned by the client. Everything that is stored at a data centre sits on a server, a server is basically a powerful pc that is capable of storing different data, or websites, that are then accessible through the network of the internet.

Windows Server is a server operating system from Microsoft Corporation. Windows Server offers ease of management through its interface. The Windows Sever web hosting environment supports major Web programming languages and databases such as PHP, MySQL, ASP.NET and MS SQL.

Application servers: These servers use special tags within an HTML file to direct processing. They also can have hooks to call external programs to handle processing that is not built into the server, and they also separate developer and server portions into separate packages.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
