4. The Web: Lesson1: Web Browser Lesson 1: Web Browser

5. The Web: Lesson1: Web Browser A web browser is a software program to access information on the world wide web (usually referred to as a browser). Upon requests by a user of a website a web page is downloaded from a database server by the web client and the link on the screen is shown. A web browser is not the same as a search engine, although it is often frustrating in both. A user is a search engine that only contains information about other websites, including Google Search, Bing or DuckDuckGo. Nonetheless, a user must have a web browser installed to connect to the website server and to view their web pages. Web Browser

6. The Web: Lesson1: Web Browser The aim of a web browser is to collector and display information resources on the Web on the device of the user. This cycle starts when a Uniform Resource Locator (URL) , such as https:/en.wikipedia.org, is entered by the user into the web browser. Nearly all web-based URLs start with either http: or https: which means the Hypertext Transference Protocol (HTTP) is used to access the URLs. For HTTPS: the browser-web server contact is encrypted for security and privacy purposes.

7. The Web: Lesson1: Web Browser The rendering engine of the browser displays it on the user's device once a Web page has been found. This includes browser-supported picture and video formats. Hyperlinks to other pages and services are usually found in websites. Each link has a URL and the browser navigates to the new source when it is clicked or tapped. This restarts the process of bringing the user content.

8. The Web: Lesson1: Web Browser For later visits to the same website, most browsers use an internal web-page cache to improve their loading times. Many things like big images can be stored in the cache to avoid being downloaded from the server. Cached items are usually only stored until the HTTP reply messages of the web server. A number of features are common to the most popular browsers. Users can set and browse in private mode by using bookmarks. Extensions can also be personalized and some of them provide a sync feature.

9. The Web: Lesson1: Web Browser Most browsers have these user interface features: • Enable the user to open multiple pages simultaneously, either in different browser windows or in various tabs in the same window. • Go back and forth to the last page you visited or to the next one. • Refreshing or reloading the current page button. • To avoid loading the page with a stop button. (The pause button is combined with the reload button in some browsers.) • A click back to the homepage of the app. • An address bar for entering and displaying the URL of a website. • A search bar for entering search engine terms. (The search bar is fusioned with the address bar in some browsers.)

10. The Web: Lesson1: Web Browser Niche browsers with different features are also available. One example is text-only browsers that can help people with poor Internet connections or visually disabled individuals. A web browser is a computer-based software program that allows users to visit their favorite websites on the Internet. Mozilla Firefox, Google Chrome, Microsoft Edge, Apple Safari and the Opera browsers are among the most popular browsers today.

11. The Web: Lesson1: Web Browser Mozilla Firefox is a free, open-source web browser developed by Mozilla Foundation and its Mozilla Corporation subsidiary (the Mozilla Firefox Quantum or simply Firefox). It operates on common systems like Windows, MacOS, Linux and Android. Firefox can add or remove browsing features and allows users to tailor Firefox to their needs. This has been done to make it safe and easy to use Firefox. Mozilla Firefox

12. The Web: Lesson1: Web Browser Features such as tabbed browsing, spell checking, gradual searching, live-bookmarking, Smart Bookmarks, a download manager, private browsing, Google-based location-ware browsing, and a built-in search feature. Mozilla Firefox

13. The Web: Lesson1: Web Browser Extensions allow the user to add or change new things to the browser. They have been created by other users. Because extensions can access all parts of Firefox 's computer, extensions could be created which could harm a computer. However, only if you have administrator privileges can the extension change system settings. Mozilla Firefox

14. The Web: Lesson1: Web Browser Firefox also has topics or skins that alter the browser's user appearance. Some themes, such as Internet Explorer and Netscape, can make Firefox look like other browsers. Browsing tabbed is a browser feature used by many webpages, where labelled tabs top up to the webpage can be opened in a window. Type control-T to make a new blank tab. Mozilla Firefox

15. The Web: Lesson1: Web Browser In the top right corner of the window there is a search box in Firefox that can be seen. The browser uses a search engine, such as Google or Yahoo, when someone with Mozilla Firefox types something into the search box and presses enter. Firefox 2 contains "search recommendations." The suggested words will be displayed when words are entered in the search box. The browser suggests for example, "Wikipedia," if "wiki" is typed. Mozilla Firefox

16. The Web: Lesson1: Web Browser If a word is wrong in a text box, like the one in which someone changes a Wikipedia page, Firefox can use the spell check, the program emphasizes the word wrongly spelled on a red line. Mozilla Firefox will list words using the right orthographer when you scroll over that word and copy the right one. For instance, "chekc" would have a suggestion for the wrong word "checkc." Mozilla Firefox

17. The Web: Lesson1: Web Browser Google Chrome is a Google-developed cross-platform web browser. It was released for Microsoft Windows in 2008, and later ported to Linux, MacOS, Android and iOS. The browser is also Chrome OS's main component, and is used as an applications portal. Google Chrome

18. The Web: Lesson1: Web Browser Most of the source code for Chrome comes from the free open-source Chromium software project, but it is licensed to Chrome as a proprietary freeware. WebKit was the original renderer, but eventually Google forced the renderer to build the Blink motor; all Chrome versions except the iOS now use Blink. Google Chrome

19. The Web: Lesson1: Web Browser Google Chrome has a simple user interface, which is later introduced in other browsers using its user interface concepts. The fusion of the address bar in the omnibox, for example. Chrome also has a good browser reputation. • Bookmarks and settings synchronization • Web standards support • Security Google Chrome

20. The Web: Lesson1: Web Browser • Password management • Security vulnerabilities • Malware blocking and ad blocking • Plugins • Privacy • Speed • Stability • User interface Google Chrome

21. The Web: Lesson1: Web Browser • Desktop shortcuts and apps • Extensions • Themes • Automatic web page translation • Release channels, cycles and updates • Color management • T-Rex Google Chrome

22. The Web: Lesson1: Web Browser Microsoft Edge is a web browser that has been created by Microsoft. It was first released on Windows 10 in 2015. It replaces Internet Explorer (IE), a browser that was originally created on Windows 95 and which for two decades was part of Windows operating systems. Microsoft Edge

23. The Web: Lesson1: Web Browser Edge is a smaller browser optimized for Web service and based on web standards. Microsoft does not currently plan to add Edge to previous Windows versions, or to supply versions of non-Windows operating systems. Microsoft Edge

24. The Web: Lesson1: Web Browser Edge has reduced the bloat that most modern browsers, including IE, have had; Active-X support has also been reduced. Edge was called the code in development "Spartan," which refers to a lightweight browser structure designed to make Edge work on multiple device platforms, often mobile. Microsoft Edge

25. The Web: Lesson1: Web Browser The same way Internet Explorer did in earlier releases, Edge installs together with Windows 10. However, IE for communication compatibility is also included in Windows 10 especially within the company. Microsoft Edge

26. The Web: Lesson1: Web Browser Edge’s features include: • Inking - an annotation tool that allows users to write or draw on Web pages. • Cortana - a personal virtual assistant from Halo, a popular video game. • Private browsing. • Security features such as Microsoft Passport and asymmetric cryptography to deter phishing and other social engineering attacks. Microsoft Edge

27. The Web: Lesson1: Web Browser • Support for Firefox and Chrome add-ons. • Faster overall page rendering. • Integration with social media. • Automatic form fill. • Uncluttered interface. • Reduced resource consumption to optimize for low-power devices. Microsoft Edge

28. The Web: Lesson1: Web Browser Safari is a Web browser based on the WebKit engine, created by Apple. A smartphone edition has been paired with ioS devices since the iPhone was introduced in 2007, and first published on desktop in 2003 with the Mac OS X Panther. The default Apple mobile browser is Safari. A version of Windows from 2007 to 2012 was available. Apple Safari

29. The Web: Lesson1: Web Browser Starting with Mac OS but has been ported to iOS and Windows since then. Safari was released for the Windows XP SP2 release for the first time on June 11, 2007. As for the iOS safari version, it's slightly different from the OS X version as it uses a different GUI, Webkit and an API. Apple Safari

30. The Web: Lesson1: Web Browser Safari is an OS X Cocoa framework and uses a rendering WebKit. WebKit itself consists of the GNU GPL free software, WebCore and JavaScriptCore, which also make Safari free. In addition, Apple releases the code under a 2-clause BSD open-source permit. Apple Safari

31. The Web: Lesson1: Web Browser Opera is the free web browser developed by Opera Software for Microsoft Windows, Android, iOS, macOS, and Linux. Opera uses Blink layout engine as a Chromium based browser. The user interface and other features make it distinctive. Opera

32. The Web: Lesson1: Web Browser Opera was designed as a research project at Telenor in 1994 and purchased in 1995 from Opera Software. For the first ten years it had been a commercial software and had a proprietary Presto layout engine. The Opera version of Presto received a number of prizes, but the production of Presto ended in 2013 following a significant Chromium transition. Opera

33. The Web: Lesson1: Web Browser Three mobile versions, Opera Mobile, Opera Touch and Opera Mini, are also available. On 11 June 2019, a gaming browser was launched called Opera GX. Opera

34. The Web: Lesson1: Web Browser Opera created features which other web browsers have later adopted, such as: speed dialing, pop-up blocking, newly opened shut-off pages, browsing privileging and tabs. Opera features a bookmarks bar and a manager for downloads. Opera also has "Call rates" enabling the user to connect an infinite number of thumbnail pages to a page shown during the opening of a new window. Speed Dial makes navigating to the selected web pages simpler for your app. Opera

35. The Web: Lesson1: Web Browser • Usability and accessibility • Privacy and security • Crypto wallet support • Standards support Opera
