Write a short note on web browser.

A web browser is essential software used for accessing websites and serves as an interface between users and the World Wide Web. Web browsers come in various forms, including those with graphical user interfaces like Internet Explorer, Mozilla Firefox, Google Chrome, Opera, as well as text-based browsers such as Lynx.

They are typically installed on individual computers, enabling users to effortlessly explore files, folders, and websites through hyperlinks. Multiple tabs and windows within the same browser can be opened simultaneously, enhancing user experience.

Web browsers offer an array of features and functionalities, including the ability to download content, save bookmarks for easy access, and manage passwords securely. They also provide tools like spell-checking, integrated search engine toolbars, tabbed browsing for efficient multitasking, ad-blocking features, accessibility through HTML access keys, and pop-up blocking to enhance browsing safety and convenience.
