A web application is an application which is accessed by users over a network such as internet. It is normally used to display images, text, video, and data which can be stored and retrieved from server. Example of web application are website, Facebook .

Now, I would to explain a little about architecture of web application that I have learned in our classes. Web applicaition is commonly combination of script , client and server.

                           

As a simple example for web application, I would to explain about website that we are familiar with. Website is the combination of web documents. Normally, we can see text and pictures in website. There are two types of website. They are static and dynamic website.

Static website are read-only website. It allows users to search and retrieve information and read it. Static website can only really be updated by someone with a knowledge of website development. As example , we can say that educational websites, and company websites are static websites. 

                             

 Dynamic websites have interactions between people , software and data. It has ability for clients or users to upload documents.Normally, it can read and write. For example , e-commerce system, and Wikipedia are dynamic websites.

 
                                       

                                            

Moreover, I would to post about generation of web application. There are three generations in web application. The first generation is Web 1.0 which information displayed are very restricted. The second generation is Web 2.0 which is very popular nowadays because it allows users to interact with web.
