What is a browser?

Information retrieval

A Web browser is a program for retrieving information on the World Wide Web. As you probably know, you are using a browser right now to view this document. To find this document, you have most likely clicked on a number of links, or you may have entered an Internet address (URL) directly into your browser's address field.

Having several browsers installed on your computer, and using them, is quite possible. Note, however, that some browsers, though not Opera, may try to take control and set themselves up as your default browser.


We Can Say That ...........................

A web browser is a software application that enables a user to display and interact with text, images, videos, music and other information typically located on a Web page at a website on the World Wide Web or a local area network. Text and images on a Web page can contain hyperlinks to other Web pages at the same or different website. Web browsers allow a user to quickly and easily access information provided on many Web pages at many websites by traversing these links. Web browsers format HTML information for display, so the appearance of a Web page may differ between browsers .

Some of the Web browsers available for personal computers include Internet Explorer, Mozilla Firefox, Safari, and Opera

Navigation with a mouse


All browsers have toolbars with a collection of buttons and fields. These buttons perform the most commonly used and most useful functions related to surfing the Web.

Go back

Browsers keep a record of a certain number of pages you have visited. Going back to a previously visited page is therefore easy -- just click on the "Back" button.

Go forward

Going forward is just as easy -- just click on the "Forward" button. Note, however, that going forward is only possible after first having gone back.

Go home

It's easy to get lost on the Internet. But it's even easier to get home. Instead of continuously clicking the "Back" button until you get back to where you started, simply click the "Home" button once. This will take you to the page you have set as your home page.


Sometimes an interruption occurs and part of a Web page is lost. Reloading the page by clicking the "Reload" button once then becomes necessary. This is also useful for pages that change on a regular basis, like newspaper sites.


If you would like to stop loading a page, often because the page is heavily loaded with images or you are at the receiving end of a slow connection, simply click the "Stop" button once.


If your system is correctly configured and connected to a printer, simply clicking the "Print" button will print the active document.
