HTML
Short for HyperText Markup Language, the authoring language used to create documents on the World wide web. HTML is similar to SGML, although it is not a strict subset.
HTML defines the structure and layout of a Web document by using a variety of tags and attributes . The correct structure for an HTML document starts with <HTML><HEAD>(enter here what document is about)<BODY> and ends with </BODY></HTML>. All the information you'd like to include in your Web page fits in between the <BODY> and </BODY> tags.
Applets
A programme designed to be executed from within another application. Unlike an application, applets cannot be executed directly from the operating system. With the growing popularity of OLE(object linking and embedding), applets are becoming more prevalent. A well-designed applet can be invoked from many different applications.
Web browsers, which are often equipped with Java virtual machines, can interpret applets from Web servers. Because applets are small in files size, cross-platform compatible, and highly secure (can't be used to access users' hard drives), they are ideal for small Internet applications accessible from a browser.
BLOGS
Short for Web log, a blog is a Web page that serves as a publicly accessible personal journal for an individual. Typically updated daily, blogs often reflect the personality of the authorWIKIS
Similar to a blog in structure and logic, a wiki allows anyone to edit, delete or modify content that has been placed on the Web site using a browesinterface, including the work of previous authors. In contrast, a blog, typically authored by an individual, does not allow visitors to change the original posted material, only add comments to the original content.
Wiki wiki means "quick" in Hawaiian. The first wiki was created by Ward Cunnigham in 1995

For example, there are number of plug-ins for the Netscape Navigator Browser that enable it to display different types of audio or video messages. Navigator plug-ins are based on MIME file types.
FILTER
A program that accepts a certain type of data as input , transforms it in some manner, and then outputs the transformed data. For example, a program that sorts names is a filter because it accepts the names in unsorted order, sorts them, and then outputs the sorted names.
