Web browsers consist of client software that runs on your computer and displays home pages on the Web. There are clients for a wide variety of devices, including Windows, Macintosh, and Unix computers.
Web browsers can't display some types of files on the Internet, notably some kinds of multimedia files, such as sound, video, and animation files. (A common file type like this is called Flash.) To view or play these files, you need what is called a helper application or plug-in. You must configure your web browser or operating system to launch these helper applications and plug-ins whenever you click an object that needs them to be viewed. More often than not, when you install the application or plug-in, it will configure itself properly.
The meanings of tags are easily decipherable. Every HTML tag, or instruction, is surrounded by a less-than and a greater-than sign<P>. Often tags appear in pairs, the beginning tag and the ending tag. They are identical except for a simple slash in the ending tag. So, a paragraph of text frequently is surrounded by tags such as this: <P> Paragraph of text.</P>. Also, tags are not case sensitive. <P> equals <p>.
