I found Something while learning html in this app but couldn't understand...

Question

(I found these while learning. Can anyone please tell me what are these and what is the roll of these. Also how to use these...)

APPLET - embedded Java applet
IFRAME - Inline frame
INS - inserted text
MAP - image map
OBJECT - embedded object
SCRIPT - script within an HTML document

Answer 1

* The obsolete HTML Applet Element (<applet>) embeds a Java applet into the document; this element has been deprecated in favor of <object>.(i explained object tag below)
*The HTML Inline Frame element (<iframe>) represents a nested browsing context, embedding another HTML page into the current one.
*The HTML <ins> element represents a range of text that has been added to a document. You can use the <del> element to similarly represent a range of text that has been deleted from the document.
*The HTML <map> element is used with <area> elements to define an image map (a clickable link area).
*The HTML <object> element represents an external resource, which can be treated as an image, a nested browsing context, or a resource to be handled by a plugin.
*The HTML <script> element is used to embed or reference executable code; this is typically used to embed or refer to JavaScript code.
