To better explain how all of this works, let’s use the example of a customer trying to purchase a plane ticket using a website. All customers see on the website is the frontend; once customers enter all their information, such as their name, billing address, or destination, the web application stores the information in a previously created database on the server where the website requests the information.
The web application creates, deletes, changes, or renames items in the database. For example, when a customer purchases a ticket, that makes an article in the database, but when they change their order or wish to cancel, change the database item.
A server is a computer accessed remotely that runs software to fulfill requests from clients in the simplest form. In our example, the server the customer’s browser is communicating with is where the database is stored and modified.
Then, in short, when a customer wants to buy a ticket, the backend operation is the web application communicating with the server to make a change in a database stored on said server. Technologies like PHP, Ruby, Python, and other’ backend programmers make this communication work smoothly, allowing the customer to purchase their ticket with ease.
For example, if you’re using Google Chrome or Firefox, the browser translates all of the code in a manner for you to see and with which to interact, such as fonts, colors, drop-down menus, sliders, or forms. However, for all of this to work, there has to be something supporting the frontend. So that’s where the backend comes in.
