Some browsers, like Brave, do a much better job than others, offering stronger protective measures and turning more of them on by default. There’s a wide variety of ways in which your privacy can be put at risk on the Web, and there’s a similarly wide variety of ways in which browsers can protect you. Privacy is a major differentiating factor among browsers. For example, some fingerprinting techniques result from browser features that were designed to allow websites to offer richer experiences, like 3D graphics. More complexity means more ways for security and privacy to be compromised. This is a difficult task, because the technology within browsers-and within the websites they access-is extremely complex. This makes it crucial for browsers to protect your security and privacy.
Much of your most sensitive information-financial data, messages with friends and family-flows through a browser, especially on desktop devices. The Web is only part of the Internet, but a large portion of what you do on the Internet is done through a browser. It’s practically impossible to avoid using a browser. Not only can you go to any search engine by typing its URL in your browser (such as ), but you can change your browser’s settings to use your preferred search engine for queries from the address bar. You can use any search engine in any browser. Brave likewise has Brave (a browser) and Brave Search (a privacy-protective search engine). Microsoft has Edge (a browser) and Bing (a search engine). The most obvious example is Google, which has Chrome (the browser) and Google Search (the search engine, often referred to as just “Google”). Browsers let you choose which search engine you want to use for queries from the address bar.Īnother point of confusion is that several companies that make browsers also offer search engines. If it’s a URL, the browser goes to that webpage directly, and if it’s a search query, the browser sends you to a search engine’s site with that query already filled in. When you put something in the address bar, the browser figures out whether it’s a URL or a search query. The confusion arises because browsers let you enter either a URL or a search query into the address bar. A search engine is a website like any other. Is a browser the same as a search engine? It lays out text and images, and responds to your scrolling and clicking. Upon receiving HTML back from a Web server, the browser interprets it to display the page on your screen, in a process called rendering. HTML specifies how the page should be laid out, what it should look like, what should happen when you click on parts of it, and so on.
The browser may then need to make additional requests, possibly to other servers, to fetch other parts of the page, like images and videos.Ī webpage comes back from the server as a chunk of plain text, marked up with special characters in a system called HTML. When you type or paste a URL into a browser’s address bar, or click on a link, the browser contacts the Web server (a computer where a website lives) identified in the URL, and asks it to send back the page’s contents. What do browsers do, and how do they work?īroadly speaking, browsers have two main functions: fetching webpages from Web servers, and presenting webpages on your screen as a visual and interactive experience. You can use any of the above browsers on any major mobile and desktop operating system, except for Safari, which only works on iOS and macOS. Together, those three account for the vast majority of all Web browsing, but there are other notable browsers, such as Brave, Firefox, and Opera.

Most operating systems come with one of them already installed: Android with Chrome, iOS and macOS with Safari, and Windows with Edge. Worldwide, the three most widely-used browsers are Google Chrome, Apple Safari, and Microsoft Edge. Note that a browser is different than a search engine. The browser “calls” the server on which a website is hosted, and then renders that site for you in an intelligible way.
