Web tarayıcısı nedir?

Web tarayıcıları, internetin her yerine ulaşarak dünyanın dört bir yanından gelen metinleri, resimleri ve videoları görmenizi sağlar.

Web çok büyük ve güçlü bir araç. 20-30 yıl içinde internet; çalışma, oyun oynama ve iletişim kurma şeklimizi değiştirdi. Nasıl kullanıldığına bağlı olarak ülkeleri birbirine bağlıyor, ticareti canlandırıyor, ilişkileri güçlendiriyor, geleceğin inovasyonlarına yön veriyor ve sayamayacağımız kadar çok internet şakasına ev sahipliği yapıyor.

It's important that everyone has access to the web, but it's also vital that we all understand the tools we use to access it. We use web browsers like Mozilla Firefox, Google Chrome, Microsoft Edge and Apple Safari every day, but do we understand what they are and how they work?

Eskiden dünyanın öbür ucundaki birine e-posta gönderebilmek bile insanları şaşırtıyordu ama bilgiye erişimle ilgili düşüncelerimiz kısa sürede değişti. Artık mesele ne kadar çok şey bildiğiniz değil, hangi tarayıcıyla veya uygulamayla bilgiye en hızlı şekilde ulaşabileceğiniz.

Web tarayıcısı nasıl çalışır?

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. This information needs to be shared and displayed in a consistent format so that people using any browser, anywhere in the world can see the information.

Sadly, not all browser makers choose to interpret the format in the same way. For users, this means that a website can look and function differently. Creating consistency between browsers, so that any user can enjoy the internet, regardless of the browser they choose, is called web standards.

When the web browser fetches data from an internet connected server, it uses a piece of software called a rendering engine to translate that data into text and images. This data is written in Hypertext Markup Language (HTML) and web browsers read this code to create what we see, hear and experience on the internet.

Hyperlinks allow users to follow a path to other pages or sites on the web. Every webpage, image and video has its own unique Uniform Resource Locator (URL), which is also known as a web address. When a browser visits a server for data, the web address tells the browser where to look for each item that is described in the html, which then tells the browser where it goes on the web page.

Websites save information about you in files called cookies. They are saved on your computer for the next time you visit that site. Upon your return, the website code will read that file to see that it's you. For example, when you go to a website, the page remembers your username and password – that's made possible by a cookie.

There are also cookies that remember more detailed information about you. Perhaps your interests, your web browsing patterns, etc. This means that a site can provide you more targeted content – often in the form of ads. There are types of cookies, called third-party cookies, that come from sites you're not even visiting at the time and can track you from site to site to gather information about you, which is sometimes sold to other companies. Sometimes you can block these kinds of cookies, though not all browsers allow you to.

Gizliliği anlayın

Nearly all major browsers have a private browsing setting. These exist to hide the browsing history from other users on the same computer. Many people think that private browsing or incognito mode will hide both their identity and browsing history from internet service providers, governments and advertisers. They don't. These settings just clear the history on your system, which is helpful if you're dealing with sensitive personal information on a shared or public computer. Firefox goes beyond that.

Firefox, takip kodlarının sizi web’de takip etmesini engelleyerek çevrimiçi ortamda daha gizli olmanızı sağlar.

Most major web browsers let users modify their experience through extensions or add-ons. Extensions are bits of software that you can add to your browser to customize it or add functionality. Extensions can do all kinds of fun and practical things like enabling new features, foreign language dictionaries, or visual appearances and themes.

All browser makers develop their products to display images and video as quickly and smoothly as possible, making it easy for you to make the most of the web. They all work hard to make sure users have a browser that is fast, powerful and easy to use. Where they differ is why. It's important to choose the right browser for you. Mozilla builds Firefox to ensure that users have control over their online lives and to ensure that the internet is a global, public resource, accessible to all.
