Web Browsing and How it Works?
A web browser (commonly referred to as a browser) is application software for accessing the World Wide Web. When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.
A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed.
How Web Browsing Works?
How does a web browser work? A web browser takes you anywhere on the internet. It retrieves information from other parts of the web and displays it on your desktop or mobile device. The information is transferred using the Hypertext Transfer Protocol, which defines how text, images and video are transmitted on the web.
Suppose,
You need to request a google search engine page so what you will going to write on the URL will be https://www.google.com.
So you will get the Google search engine page directly. But Do you have any idea
What's the process behind that?
I real world this how its work
First our Request goes to ISP(Internet Service Provider), ISP then transfer our request to DNS.
And Now question is what is DNS?
DNS Is a kind of Library which holds number of IP Addresses and return the IP Address of the particular URL which has been questioned to it.
In this case its https://www.google.com.
Then the request with some IP Address comes back to ISP and the ISP send the response to our client machine.
But hold on, How its shown as a google search page.
It has a separate story behind it.
In the picture above the response returning with three files HTML CSS and JavaScript
Yes that's the answer.
We got response in the form of a web page which has built with a base made by HTML some beautiful page designs made by CSS and the functionality made by JavaScript.
Yes there are some other files to like images videos or some documents we get too. but that depends Totally on which request we a performing.
So as In the above picture we can see. that Google server has sent a response to the client machine in the form of Html CSS and Java script.
And then we got what?
We got our response as Google search page
So This is how Web browsing Works Hope you have enjoy the Blog. And If yes Please leave a nice comment for the motivation....
