Hi guys!

Are you all right?

I'm here, but one time with you to chat about technology.

The subject this time is the differences about the differences of a developer Back-end and a Front-end.

So let's get down to business.

What is Backend and Frontend?

Back-end and front-end are the fundamental parts of software development.

The websites you access and browse daily, the applications on your mobile devices, the systems, the web that you interact with when buying or selling something. They all have these two main parts that are in charge of delivering the expected product or service.

More after all what is a Front-end developer

You've accessed some websites today, viewed all the pages, seen categorized navigation menus and layout defined with beautiful colors, everything organized.

If yes! Very good!

You have viewed and interacted with the front end of the website.

That is, everything that the user can view, click or have some other type of interaction is the front-end that is responsible for making this happen.

Responsiveness and performance are two main goals of a front-end developer.

The developer must ensure responsiveness, that is, that it appears correctly on devices of all sizes that exist. No part of the site should behave abnormally, that is, it has to be working perfectly, regardless of the screen size.

All details are important, since the user who is accessing a website or application is consuming content that he deems relevant or even made a purchase, for example.

Nothing can be more unpleasant for a user than an unfriendly interface, right?

That can make the user give up making a purchase or making a request for a layout that is not working well.

Frontend languages

Examples of front-end languages are:


HTML stands for Hyper Text Markup Language. It is used to design the front-end part of a web page, with its hypertext markup language.

Hypertext defines the link between web pages and markup language is used to define the text documentation within the tag that defines the structure of the pages.


CSS is a simple design language intended to simplify the process of making web pages more presentable.

It allows you to apply styles to web pages and to do so independently of HTML.


JavaScript is a programming language used to trigger user interaction with a website or application. He is the one who allows you to implement cool games and web-based software.

Today JavaScript is the most used language and is supported by all major browsers on the market without the user having to install any plug-in.

And what is a Backend developer

On the other hand, the backend is the part that no one sees, that is, everything that runs on the server linked to the intelligence of the website or application to deliver what the frontend uses. It's the backend that does the execution.

In a way, the backend works for the frontend, and with both parties, the result is achieved and the delivery of the product or service is completed for the user.

It is important to emphasize that. Among some technical assignments, it is in this part that it is defined how the server will communicate with the application's database as well as handle the front-end communication with the server used.

Here, communication must be objective in such a way that what works, what doesn't work, and how to deal with errors is identified, minimizing the possibility of returning the same problems.

Backend Languages

Examples of backend languages are:


PHP is a server-side scripting language specifically designed for web development.


Java is one of the most popular and widely used programming languages and platforms. It is also famous for being highly scalable.


Python is a programming language that lets you work quickly and integrate systems more efficiently. It is very popular and made to be simple and practical.

What is the difference between frontend and backend?

Frontend and backend development are quite different from each other, but still, they are two aspects of an iceberg, i.e. one part you see and the other part you don't, but both are there.

That is, the front-end is what the user sees and interacts with, and the back-end is the foundation that sustains everything.

Let's also say that the front-end is the part of the website that the user can see and interact with, with the graphical interface and the command line, including the design, navigation menu, texts, images, videos, etc.

And the backend is the other way around, it's the part of the website that users can't see and interact with.

a tip: the Front-end deals with sensitivity and Communication back-end.
