What does a Web Browser? How does it work?

A web browser is a software database that permits users to search, access, and view web pages. In common parlance, a web browser generally abbreviates “browser.”

Web browsers primarily use to view and access websites on the Internet and other content created with languages ​​such as Hypertext Markup Language (HTML) and Extensible Markup Language (XML).

Browsers translate web pages and websites served using the Hypertext Transfer Protocol (HTTP) into human-readable content. You can also see other protocols and prefixes, such as These include Secure HTTP (HTTPS), File Transfer Protocol (FTP), email processing (mailto :), and files (file :).

Additionally, most browsers also support external plugins required to display dynamic content such as video, audio, and game content on the page.


The initial web browsers started with a text-only browser called Lynx and Mosaic before the 21st century.

Later, Netscape Navigator and Microsoft Internet Explorer emerged as the top two options until Mozilla Firefox hit the market in 2004.

Meanwhile, Apple’s Safari products hurled in 2003 and became the default operating system for the company’s iPhones in 2007.

Since then, Google Chrome has also become a competitor in the browser wars, competing for most of the end-user activity.

What does a Web Browser do?

Essentially, a web browser knobs HTTP activity between a client and a server, the backbone of using the World Wide Web. URLs are traffic addresses for the web browser, and the browser uses IP addresses and other tools to make these connections.

In addition to making Internet browsing easier, newer web browsers offer additional functionality through several add-ons that can add later. Around these have to do with security and convenience, while others have to do with end-user convenience or data aggregation.

Continuous Web Browser Development

Some of the most important news in web browsers have to do with cybersecurity. For example, Google Chrome was a pioneer in hardening IT systems against websites that do not have a valid SSL certificate, preventing various types of hacking and security breaches.

Web browsers can also configure to process newer protocols, such as those created by the Internet Engineering Task Force to increase web security.

Other emerging technologies include the idea of ​​browser isolation, in which companies segment activities and separate internal network activities from web browser activities.

If browser activity can be placed outside of a firewall and monitored inbound, the internal network may be better protected.

Meanwhile, the underlying web coding languages ​​have also evolved. HTML became HTML 5, and Cascading Style Sheets, or CSS, have revolutionized the way a consistent site design is maintained.

The web browser is a favorite technology in the average user’s system tray, but it is still evolving and evolving to meet our modern Internet needs.

Interestingly, with the advent of the Internet of Things (IoT) phenomenon, in which various devices access the Internet, only traditional instruments such as cell phones and laptops actually use a browser design.

Other devices can only send and receive data without events controlled by the end-user. However, appliances such as smart refrigerators and other smart home devices may have web browsers installed.

These can fundamentally differ from previously known web browser designs.

For example, early implementations of smart refrigerator web browsers show how they promote certain types of visual interfaces built into the front of the device and the ease with which some web browsers can hack with malware infecting the refrigerator.
