 So, in this module, we'll talk about the difference between a website and a web application. Now, many people consider a website similar to a web application and a web application similar to a website. And sometimes people use them interchangeably, but they're quite different in their scope, in their domain, in their application, and in their complexity and difficulty level, their audience. So, I will give you a brief comparison of a website and a web application. So, let's proceed ahead. So, what is a website? As you can see on your screen, that a website is a collection of related pages. And these pages are on the same domain. And there are certain technologies which are used to develop the web pages. And those technologies are, of course, used also for developing web applications, but they are more focused towards a website. Now, if you look at the screen right now, so we have what is a web application? A web application consists of a collection of programs. And those programs are running on that domain, on that address, and that combination of programs, different applications, different middleware, that can be databases also, those are used collectively to have what is called as a web application. And the main goal of a web application is to make the user's response to provide certain information, certain data, certain value to the users. So, as opposed to a website, a web application is not about marketing something, is not about getting yourself known on the internet, but a web application provides information to the users, to interact with the users. So, over C, we can see over here that in a website, a user makes a request to a page, and something comes back in return. The user makes a request, and something comes back in return. Now, this is the case for a website, so we see that depending upon which page the user clicks, the same page is going to appear again and again, until of course the user changes that page. And if I change the sequence of the pages, for example, if I make a request something like this, and make a return like this, the contents of the page are not going to change. It is going to remain the same, that is the case for a website. So, a website is more or less static in nature. A website, the pages don't change, the pages are the same. As opposed to a website in a web application, the user makes a request maybe inputs in a form, that form then goes to the web application server. There may be a backend database also, there can be a backend database over here also, and the results are retrieved from that backend database, go to the web application, go to the dynamic output, this is the middleware, here the data which comes from the database is converted into an HTML page, and that page is presented to the users. So, we see that in the context of web application, the pages are dynamic in nature. They are changing as per the user input, and they are not static as opposed to a website. And of course, now I will give you a comparison in a tabular form, which will make you understand things much better. So, number one, a website is for promotion of the brand. A website is for the promotion of an individual, the promotion of the product, the promotion of the services, but as opposed to a website in a web application, there are tools which perform certain operations for the user, to facilitate the user. Then of course, for a website, there is data there, of course, information there, and that data and information is used to present the results for reading something, for comprehending something, right? But as opposed to a website in a web application, there is more focus on search, say for example, Google, a huge search engine, or maybe there are catalogs over there, and analysis is also performed, analytics is also there. There is a difference between a website and a web application. Then for a website, there is hardly any authentication services. The reason being that a user comes, looks at my content, reads the contents, and then leaves. But as opposed to a website in a web application, there is, the portals are there. For example, if I want to post something on Facebook, I need to log in. But if I don't post something, I don't need to log in. So websites are used for communication purposes, and the web applications are used for automating the task. Say for example, I would like to make a reservation to buy a ticket on a bus, on an airplane, so that is a web application, that is not a website. A website is less resource intensive, does not require complex programming, as opposed to it. And then of course, in a summary, we can see on your screen that a website is a different animal as compared to a web application.
