Functions of a Web Browser

A web browser is a medium through which you can basically access different websites.

• The main function of a web browser is to provide an interface to the user for sending requests and fetching data/information from the web servers.
• It also displays the information to the user including multimedia elements (images and videos) in the form of webpages, using CSS and JavaScript.
• A web browser acts as a platform to access various websites. Users can visit different websites by just entering the URL of the website on the web browser.
• Browsers also have navigation features like a navigation bar, tabs, and other tools which make surfing the net easier. One can also open multiple web pages at the same time, reload, and navigate forward and backward between web pages.
• Another function of web browsers is to ensure secure and safe access to websites. This is accomplished by pop-up warnings, scanning for malicious software and other safety measures.
• The functionality of browsers can also be improved by adding extensions or plugins to the browser. Most commonly installed extensions include AdBlock, Calendar and other constructive tools.
• The data accessed by a user frequently is stored by the web browsers in the form of cache. This saves the loss of data and time while accessing the data again and again.
