Q:Describe how to access the Internet. What are the providers? Define browsers and discuss URLs, HTML, javascript, AJAX, applets, and mobile browsers.

A:The most common way to access the internet is through an internet service provider(ISP).

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) commands.The browser interprets the HTML commands and displays the document as a Web page. Web pages also can contain special programs called applets that are typically written in a programming language such as Java.Java applets are widely used to add interest and activity to a Web site by presenting animation ,displaying graphics,providing interactive games,and much more.
