Describe how to access the Internet. What are the providers? Define browsers and discuss URLs, HTML, javascript, AJAX, applets, and mobile browsers.
Through an Internet service providers can access the Internet.
The providers are already connected to the Internet and provide a path or a connection for individuals to access to the Internet.Your college or university most likely provides you with free access to the Internet.There are also some companies such as Netzero and Juno that offer free Internet access.
Browsers are programs that provide access to Web resources.
For browsers to connect to resources,the location or address of the resources must be specified.These addresses are called uniform resource locators(URLs).Once the browser has connected to the Web site,a document file is sent back to your computer.this document typically contains Hypertext Markup Language(HTML).The browser interprets the HTML formatting instructions and displays the document as a Web page.A language called javascript is often used to trigger simple interactive features.AJAX is used to create interactive Web sites that respond quickly.applets are written in the Java programming language .These programs can be downloaded quickly and run by most browsers.Mobile browsers are designed to run on mobile devices.A mobile browser is displayed on a very small screen and special navigational tools are required to conveniently view web content.
