Copying a Web page onto a server is called publishing the Web page. This process is also called
posting or uploading.
HOW DOES THE WEB WORK?
Web documents can be linked together because they are created in a format known as hypertext.
Hypertext system provides an easy way to manage large collections of data, which can include text
files, pictures, sounds, movies and more. To support hypertext documents, the Web uses a special
protocol, called the Hypertext Transfer Protocol (HTTP). The language allows a document’s author
to embed hypertext links— also called hyperlinks or just links in the document. HTTP and hypertext
links are the foundations of the World Wide Web.
USING WEB BROWSER
For several years, the Web remained a tool used by scientific researchers. But in 1993, developers at
the National Center for Supercomputing Applications (NCSA) created Mosaic, a point and click
Web browser. A Web browser is a software application designed to find hypertext documents on
the Web and then open the documents on the user’s computer. Commonly used web browsers are
Google Chrome, Microsoft Edge, Mozilla Firefox, etc.
Launching Your Browser
You may need to connect to the Internet before launching the browser. Once you have established
a connection, launch your browser by following the given steps:
3 Click on Microsoft
Edge. The Microsoft
Edge window will appear.
1 Click on search box. 2 Type Microsoft Edge.
USING URLs
You have learnt in the previous class that every Web page has a unique address, called a Uniform
Resource Locator, or URL. URLs help you to navigate the web. When you provide a URL to the
browser, the browser finds that URL’s Web page and then transfers the Web page to your PC. The
content of the web page then appears in the Web browser window. You can specify a URL in several
ways, but two methods are commonly used. Let us discuss about them.
