What parts make up a web browser

What does an internet browser do?

An internet browser takes you anywhere on the internet and enables you to see texts, pictures and videos from all over the world.

The internet is a huge and powerful tool. Over the course of a few decades, the web has changed the way we work, play, and interact with one another. Depending on how it is used, it forms a bridge between nations, drives trade, promotes relationships and ensures future innovations. Plus, it probably got us more memes than we can ever use.

It is important that everyone has access to the web. But it's also critical that we all understand the tools we use to access them. Every day we use web browsers such as Mozilla Firefox, Google Chrome, Microsoft Edge and Apple Safari. But do we understand what browsers are and how they work? At first we just loved the fact that we could email someone anywhere in the world, but now we think a little differently about information. Now it's no longer just a question of how much you know, but which browser or app can be used to access information most quickly.

At first we just loved the fact that we could email someone anywhere in the world, but now we think a little differently about information.

How does an internet browser work?

An internet browser will take you anywhere on the net. It pulls information from other parts of the internet and shows it to you on your desktop or mobile device. This information is transmitted using the Hypertext Transfer Protocol. This defines how text, images and videos are transmitted in the network. Such information needs to be shared and displayed in a consistent format so that no matter what browser they are using, people around the world can see this information.

Unfortunately, not all browser manufacturers interpret the format in the same way. For users, this means that a website can look and function differently. The creation of uniformity with the aim of ensuring that every user can surf the Internet equally regardless of the browser they are using is summarized under web standards.

When the Internet browser pulls data from a server connected to the Internet, it uses software called a rendering engine. This translates the data into text and images. This data is written in Hypertext Markup Language (HTML). Internet browsers read this code in order to generate what we see, hear and experience on the Internet.

Hyperlinks enable users to follow a path to other websites. Every website, every image and every video has its own unique Uniform Resource Locator (URL). This is also known as the Internet address. When a browser requests data from a server, the Internet address informs the browser where to find every element described in the HTML. The browser is then informed where it is located on the website.

Cookies (not the delicious ones to eat)

Websites store information about you in files called cookies. Cookies are stored on your computer for your future visits to the same website. When you return, the website code reads this file and recognizes that it is you. For example, if you visit a website and it remembers your username and password, a cookie enables it.

There are also cookies that can remember detailed information about you, such as your interests, your behavior patterns when surfing the web, etc. This means that a site can provide you with more targeted content - often in the form of advertising. There are types of cookies that are called Third party cookies and that originate from sites that you are not even currently visiting and that can track your activities from site to site in order to collect information about you. This information or data is sometimes sold to other companies. Sometimes you can block these types of cookies. But not all browsers allow you to do this.

For example, if you visit a website and it remembers your username and password, this is made possible by a cookie.

Understand data protection

Almost all larger browsers have a function for private surfing, which can hide the history from other users on the same computer. Many people think that private browsing mode, or incognito mode, would hide both their identity and history from internet service providers, governments and advertisers. That's not the case. These settings only delete the history on your PC system. This is useful when you are dealing with sensitive personal information on a shared or publicly accessible computer. Firefox goes beyond that.

Firefox helps you better protect your privacy online. Here you have the option of simply blocking trackers who want to follow you through the network.

Adapt your internet browser to your needs

Most major Internet browsers allow users to change settings via extensions or add-ons. Extensions are software that you can add to your browser in order to customize it or to provide more functionality. Extensions enable, for example, the activation of new features or foreign-language dictionaries. You can also use it to change and customize the look of your browser.

When developing their products, all browser manufacturers attach great importance to the fact that images and videos are displayed as quickly and smoothly as possible so that you can get as much out of the Internet as possible. They all work hard to ensure that users can enjoy a browser that is fast, powerful, and easy to use. However, the reasons for doing this differ. It is important that you choose the right browser for you. Mozilla developed Firefox to ensure that users were in control of their online lives and to help ensure that the Internet is accessible to all as a global public resource.
