How Front End talks to Back EndKavita
Before we understand the communication channel between Front End and Back End, let’s understand the core player of Web Development. As you all know the web is very frequently interchanged with the internet. The Internet is a global computer network which provides any information anytime with no cost over an open network. So-called Web Client requests the information and server provide the variety of information. To establish the communication between Web Server and Web Client, we need to take the help of Web Application. So before we move on our today’s topic, first let’s understand the terminology used on the web.
Key Component of Web:
Web server is a program who processes the request of web client using HTTP protocol. Web Server and Web client exchanges the web pages to communicate with each other. Web Server is a smart system who is always ready to provide the listed service to every client. It also takes the responsibility to maintain the secrecy of data. Every web server is configured to handle various challenges triggers on daily basis. Always a web server is connected to the internet. Every Web server that connects to the Internet will be provided with a unique address which was arranged with a series of four numbers between 0 and 255 separated by periods. The available web servers are IIS, Apache, Biztalk and so on…
A web client is an application who request required resources to a web server, using Hypertext Transfer Protocol (HTTP). Web clients are designed to receive the response send by Web Server. Every web client interprets the response and renders on a respective client. The examples of web client are Internet Explorer, Opera, Safari, Google chrome, etc…
Websites are the collection of web application hosting together on a web server. This contains various components of User Interface and Business Interface integrated together to provide the right information at right time. Web applications are developed using the scripting languages.
A script is a set of instructions. Scripting language helps to develop the web application which either can execute at client side and at the server side. The scripting language is a very powerful language. This helps to develop static and dynamic kind of web application. The scripting language is the useful tool to develop the responsive and interactive web application. There are the two types of Scripting Language: one is client and side and another is server side.
Client Side Scripting (Front End Programming):
Client Side scripting helps to develop the dynamic application which gets processed at browser and browser interpret at the client side. Client-side programming helps to develop user interface, with which the user interacts. A client-side script consists of plain text and runs on the client’s browser.
Server Side Scripting (Back End Programming):
Server-side scripting tends to be used for allowing users to have individual accounts and providing data from databases. It allows a level of privacy, personalization, and provision of information that is very powerful. E-commerce and social networking sites all rely heavily on server-side scripting.
The script is interpreted by the server meaning that it will always work the same way. Server-side scripts are never seen by the end user. They run on the server and provide results which are sent to the client. In terms of Security, server-side scripts are more secure than client-side scripts. Server-side scripts are more compatible then the client side as it can be controlled and organized very easily with a single language and by hosting server.
