In this Knowledge bit, we will start learning about Backend, we will discuss and give an introduction to the backend. We will review how internet works then we will discuss the difference between static and dynamic site. We will also discuss that what is backend and how it is different from front-end.
How does the Internet work?
Let start by reviewing that how the internet works. When we open our browser and type any URL and press enter then few things happens behind the scene.
The first thing our computer needs to figure out what the IP address of the site that we want to load or what is the IP address of the site we want to send the request.
For example: – if we type www.geeksread.com in our browser and press enter then it will take the URL and then get the correct IP address which is the unique locator for GeeksRead server. Then once we have the IP address then our computer will send an HTTP request to that IP address. Then the GeeksRead server gets the request and then it figures out what to do and then it responds with something.
This is how the actual content look like before our browser takes care of it and renders it for us and convert that data into meaningful content. Now, This is the content that our computer sees.
So it all started with the URL that we typed in our browser then our computer finds the IP address and then sent the request for the data or particular page to that IP address. Then server receives our request and responds with the data or particular page that we have asked.
Difference Between Static and Dynamic pages:
The next thing we will discuss is the difference between static vs dynamic pages. There are two different types of website static pages and dynamic pages.
For example: let’s take an example of Twitter and Facebook, every time we reload our page we get different content like different posts, page suggestion etc.
