Web Server vs Application Server
This article explains in detail about the Web Server and Application Server.
Both the servers function together to render the information, data or content that the visitors request from the website.
But each of the server do not perform same functions. Both have their respective area of concern on which they focus.
Web Server receives request from browser whenever the visitors browse any website over HTTP protocol.
Once the server receives the request it renders the static contents as response to the visitor (client) via HTTP only. Static content can include image, audio, video or other contents.
A web server is required for hosting your website.
Suppose you have created a static website that you wish to be available online. This will only be possible with the help of web server that you will have to purchase from web hosting companies like GoDaddy,Hosting Raza, etc.
A web server must be properly chosen analyzing the traffic of the website. If the web server is not capable of handling the traffic coming to your site then service will get impacted and it will also result in declining popularity of your site among your visitors.So choose a web server which can handle the traffic to your site.
A web server has unique IP address.

While you are booking a flight ticket, an application server makes sure to call the bussiness logic, contact with respective data base to give you real time details of current availability, fares, etc.
