Architecture of the Web
The Web is based on the two-tier architecture. The two-tier architecture is Client - Server architecture where direct communication takes place between the Client and the Server. Client is the computer program making a request over the web and Server is the computer program responding to that request. The requests can be from different clients. In the two-tier architecture, there is no intermediate between Client and Server.
In this Figure Show the underlying basic architecture of web diagrammatically.
The HTTP Protocol is a request/response protocol based on the web architecture where web browser acts as a HTTP client and web server acts as a HTTP server. Web client sends a request to the web server and web server processes the request with Server Side Scripts and database and responds with the requested information to the web client. Server Side Scripts are the scripts providing the customized interface to the web client.
The prominent components of the web architecture are:

| Components | Description |
|---|---|
| Web Client | A Web client or simply a client is the computer that requests for information from the server. For example, you are looking for booking a ticket through a website www.movie.com For this, you will open the browser on your computer and type www.movie.com in the address bar of the browser. In this scenario, your computer act as a client, which is making request to the web sever to provide you the move.com site.Internet is the medium through which your requests reaches the web server. |
| Web Browser | Web browser is a software which is required on a client computer for displaying the content of the websites. Some of the popular web browsers are Google Chrome, Firefox. The navigation of information on the web through these browsers is called surfing or browsing. There are two types of browsers: Graphical:It Provides access to text, images, audio and video present in documents over the web such as Firefox and Safari. Text:(t Provides access to the documents over the web in text-only mode such as Lynx. |
| Web Server | A web server or simply the server is the computer that receives the request from the client, finds the resources of the request made and returns the response to the client. In this case,the server looks for the movie.com website and sends is to the client. Every web server has unique address called IP address.IP address of a web server is specified during the registration of its domain name. |
| HTTP Protocol | HTTP, Stands for Hyper Text Transfer Protocol, is used to transmit files between servers and clients. When you fill out a form on the Internet, the information needs to be sent to the servers and clients. When you fill out a form on the Internet, the information needs to be sent to the server. The operation of sending the information from client to the server is performed by HTTP. it acts as messenger that fetches files to and from servers and delivers the results to the client computer. |
