Lesson Summary

 * A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web.
 * The most popular web browsers are Google Chrome, Microsoft Edge (preceded by Internet Explorer), Firefox, Safari, and Opera.
 * The primary purpose of a web browser is to bring information resources to the user ("retrieval" or "fetching"), allowing them to view the information ("display", "rendering"), and then access other information ("navigation", "following links").
 * The prefix of the URL, the Uniform Resource Identifier or URI, determines how the URL will be interpreted.
 * The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP).
 * Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for the File Transfer Protocol, and file: for local files.
 * Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user's default e-mail application, and news: URIs are passed to the user's default newsgroup reader.
 * HTML and associated content (image files, formatting information such as CSS, etc.) is passed to the browser's layout engine to be transformed from markup to an interactive document, a process known as "rendering".
 * Most browsers can display images, audio, video, and XML files, and often have plug-ins to support Flash applications and Java applets.
 * All major web browsers allow the user to open multiple information resources at the same time, either in different browser windows or in different tabs of the same window.
 * Major browsers also include pop-up blockers to prevent unwanted windows from "popping up" without the user's consent.
 * Most web browsers can display a list of web pages that the user has bookmarked so that the user can quickly return to them. Bookmarks are also called "Favorites" in Internet Explorer.
 * In addition, all major web browsers have some form of built-in web feed aggregator.
 * Most browsers can be extended via plug-ins, downloadable components that provide additional features.
 * Most major web browsers have common user interface elements:
 * Back and forward buttons to go back to the previous resource and forward respectively.
 * A refresh or reload button to reload the current resource.
 * A stop button to cancel loading the resource. In some browsers, the stop button is merged with the reload button.
 * A home button to return to the user's home page.
 * An address bar to input the Uniform Resource Identifier (URI) of the desired resource and display it.
 * A search bar to input terms into a web search engine. In some browsers, the search bar is merged with the address bar.
 * A status bar to display progress in loading the resource and also the URI of links when the cursor hovers over them, and page zooming capability.
 * The viewport, the visible area of the webpage within the browser window.
 * The ability to view the HTML source for a page.
 * An incremental find features to search within a web page.
 * A browser extension is a plug-in that extends the functionality of a web browser.
 * Many browsers have an online store that allows users to find extensions and see lists of popular extensions.
 * Browser extensions are used for improving a browser's user interface, security or accessibility, blocking advertisements, and various other features to make browsing the internet easier and more pleasant.
 * Browser extensions have access to everything done by the browser, and can do things like inject ads into web pages, or make "background" HTTP requests to third-party servers. As a result, a malicious browser extension may take action against the interest of the user that installed it.
