What is a Web Browser and How Does it Work
Wikipedia defines Web browser as a software application that enables a user to display and interact with text, images and other information typically located on a Web page in a site on the World Wide Web or a local network.
Build a web page is actually not as it appears in a Web browser. A website is written in coded form in HTML, PHP or another language. Web browser, this information and formats into the display, which we normally see when we visit a website.
may appear because of the inherent differences in browsers the displayed page slightly differently in different browsers.
If you want to see how a website has actually written, do a right click and select “view source”. You will see a mess of commands and text make no sense. The browser converts this clutter into understandable representation.
Like most people, you could have used one or two web browsers. But there are many of them available. Internet Explorer is the most common browser used by most people. Other web browsers are Mozilla Firefox, Safari, Opera and Netscape.
Although browsers are typically used to access the World Wide Web, they can also be used to access information from Web servers on private networks can provide. They can also be used to access content in file systems such as ebooks, etc.

Web pages are removed using a URL (Uniform Resource Locator), which is treated as an address, starting with http:for HTTP access. Many browsers also support a number of other protocols, such ftp:for FTP (File Transfer Protocol), rtsp: for RTSP (Real-Time Streaming Protocol-A protocol for use in streaming media systems), and https: for HTTPS ( an SSL-encrypted version of HTTP used to specify a secure HTTP connection).
In addition to HTML, PHP and other languages, the Web browser also supports various image formats such as JPEG, PNG and GIF. The combination of HTTP content type and URL protocol specification allows Web page designers embed images, animations, video, sound and streaming media into a web page or make available through the Web site.
