What Does A Web Browser Do?
The World Wide Web is a vast information network where web resources and documents are identified through Uniform Resource Locators, that can be linked by hyperlinks. The information is stored in a repository, such as a server, which can be accessed from a browser or a search engine. A web page is the document that a user can access to access the web. A web browser displays web pages in a browser window, and web servers serve web pages from their server on the Internet.
Users visit websites of many kinds, including news sites, e-commerce sites, blogs, business and personal pages, user profiles, and search engines. A web browser serves several distinct purposes. The primary role of a web browser is to display web pages, that the user has requested through a link, from a web server. In this role, a web browser acts much like a desktop computer, where applications run in the background so that the user’s interaction with the system is smooth and efficient. Users can use a web browser to access any web page, regardless of whether it is a static web page or a dynamic website, such as a social networking site.
Another role of a web browser is to provide information about web pages to the users. In this role, a web browser becomes a search engine, because it helps the user to find the web page that is requesting more information. For example, if the user has entered a web page address in the address bar, such as “myfirstsite,” the browser will search for other web pages that have the address “myfirstsite.” If the user is interested in the site she has just visited, she will click on a link to that site, and the browser will display a list of web pages that have links to them.
Some browsers, such as the Mozilla Firefox browser, are used for e-commerce sites as well. The Firefox browser is widely used for running e-commerce websites, because it is free and easy to use, and also because Firefox is one of the most widely supported browsers on the web. Google Chrome, which is the second most popular browser, is also used for running some e-commerce websites.
Web browsers and web applications also allow for social networking websites, such as Facebook and Twitter. These websites allow people to share pictures and videos, and also send text and picture messages to each other. Some of these websites use a form of Java script to give users access to the features of a personal website. Users may also be able to post their own content to web pages that they create. This content may include articles, photos, links, and widgets that allow users to customize the look and functionality of the websites.
