The document discusses web browsers and describes how to create a simple web browser called "Sparton" using Visual Basic in Visual Studio. It provides information on common web browsers like Chrome, Firefox, Opera, Internet Explorer, and Safari. It also explains the main components of a web browser, including the user interface, rendering engine, networking, JavaScript interpreter, and data storage. The document then demonstrates how to add buttons, a text box, and a web browser control to the Visual Studio form and provides the basic coding to enable navigation functionality.

9.  The browser main functionality is to present the web resourced
you choose by requesting it from the server and displaying it on
the browser window.
 The resources is usually an HTML document, but may be also a
PDF, image, or other type.
 The location of the resources is specified by the user using a
URI (uniform resources Identifier.
 As you write URL and hit GO button , browser program sends a
request to a web server program running on the remote
computer.
 The server program, gathers the request from the web browser
tries to hunt for the web page and then formulate a response.
 THE BROWSER'S MAIN FUNCTIONALITY

10. The way the browser interprets and displays HTML files is
specified in the HTML and CSS specifications. These
specifications are maintained by the W3C (World Wide Web
Consortium) organization, which is the standards organization for
the web. For years browsers conformed to only a part of the
specifications and developed their own extensions. That caused
serious compatibility issues for web authors. Today most of the
browsers more or less conform to the specifications.

11.  Browser user interfaces have a lot in
common with each other. Among the
common user interface elements are :
o Address bar for inserting a URI
o Back and forward buttons
o Bookmarking options
o Refresh and stop buttons for refreshing or stopping the
loading of current documents
o Home button that takes you to your home page

12.  COMPONENTS OF WEB BROWSER
1 User Interface
This includes the address bar, back/forward button ,
bookmarking menu etc
2 Rendering Engine
o Rendering, that is display of the requested contents on
the browser screen.
o By default the rendering engine can display HTML and
XML documents and images

13. Networking: for network calls such as HTTP requests, using
different implementations for different platform behind a platform-
independent interface.
JavaScript interpreter. Used to parse and execute JavaScript
code.
Data storage. This is a persistence layer. The browser may need
to save all sorts of data locally, such as cookies. Browsers also
support storage mechanisms such as localStorage, IndexedDB,
WebSQL and FileSystem.

15. WHAT DOES BROWSER DO?
 When you type a web page address such as
www.facebook .com into your browser, that web page
in its entirety is actually stored on a server ready and
waiting to be delivered.
 In fact each web page that you request is
individually created in response to your request.

16. HOW WEB BROWSER WORK
 LIKE much of the internet, the world wide web operates on a
client/server model.
You run a web client on your computer called a web .
That client contacts a web server and requests information or
resources.
 The web server locates and then sends the information to the
web browser, which displays the results.

17. NOW WE CREATE A SIMPLE
BROWSER
IN VISUAL BASIC AND THE
BROWSER NAME IS “SPARTON”

18. Simply Open Visual Studio (Any Version)

19. NOW IN FILE MENU SELECT “NEW PROJECT”

20. THEN YOUR SCREEN IS LOOK LIKE THIS

21. NOW GO TO TOOLBOX AND ADD 6 BUTTONS

22. NOW WE ADD TEXT BOX

23. NOW WE ADD WEB BROWSER FROM TOOLBOX

24.  NOW WE CAN CHANGED THE BUTTON NAME AS OUR
NEED
 We also changed the layout or apperence of the
web browser screen
 And we also use our images to background of
web browser

25.  NOW OUR BROWSER LOOK LIKE THIS

26.  NOW WE CAN ADD URL TO OUR WEB BROWSER

27. NOW ITS TIME FOR CODING
Click on any button for its coding
Simply we click on go button

28. THE CODING SCREEN IS LOOK LIKE THIS

29. NOW AS IT IS LEFT 5 BUTTONS CODING ARE

30. NOW OUR BROWSER IS READY BUT WE CAN
CHANGE THE LAYOUT , SCREEN ORIENTATION ,
MINIMISE , MAXIMISE OPTIONS FOR OUR BROWSERS
BETTER PERFORMANCE.

31. NOW WE SUCCESSFULLY CREATE A WEB BROWSER

32.  Finally our browser “SparTon” is ready
