HTML is the short form for Hypertext markup language. HTML defines the organization and design of a Web document by using a variety of tags and attributes. When you write a normal document using a word processor like Microsoft Word/Office, your text is saved in a file with a special format. It is not simply saved as the string of words you typed since the document needs to conserve things like the font you chose, which words are in italics, which bold, and so on. The special format includes not only your words, but all these additional information so that the next time Word opens your document; it can display the document with the precise appearance you created earlier.

When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser's Java Virtual Machine (JVM).

In computer programming, a filter is a program or section of code that is designed to inspect each input or output request for certain qualifying criteria and then process or forward it accordingly. This term was used in UNIX systems and is now used in other operating systems. A filter is "pass-through" code that takes input data, makes some specific decision about it and possible transformation of it, and passes it on to another program in a kind of pipeline. Usually, a filter does no input/output operation on its own. Filters are sometimes used to remove or insert headers or control characters in data.
