a) <form>

<form> tag is used to create HTML form for user input
HTML form has various elements like inputbox,buttons,etc.

For example:

<form>
Name: <input type="text" name="studentname" required><br>
<input type="submit" value="Submit">

The above code creates a form with text box and button.

b) <table>

This tag is used to create table on a web page.
This tag consists of sub elements to define the structure of table.

<tr> tag is used to define new row

<th> tag is used to define table header

<td> tag is used to define table data

<table> tag has various attributes to represent a table in a better way like align, - For example

<table>
<tr>
<th>Subjects of IT Sem IV</th>
<td>Applied Mathematics</td>
<td>Web Programming</td>
<td>Automata Theory</td>
<td>Computer Organization and Architecture</td>
<td>Information Theory and Coding</td>
<td>Computer Networks</td>
</tr>
</table>

c) <iframe>

The HTML iframe element inserts a frame inside a document.
This frame works almost exactly as the HTML frame element, except that the last can only be inserted in a frameset (HTML frameset element).
This is useful for displaying a document in a portion of another document.
The document displayed inside this inline frame, is specified in the "src" attribute.
In XHTML 1.0 the "name" attribute for this element has been deprecated in favor of the "id" attribute.
On the other hand, the "align" attribute was deprecated in HTML 4.01. Therefore, their use is no longer recommended.

Example:
```
<iframe src="https://kt280.com " frameborder="1" width="100%" height="200">
```
If you see this message, it means that your browser doesn't support frames or they are disabled. You can access the information shown in this frame here:
```
<a href=" https://kt280.com ">Engineering Solutions</a>
</iframe>
```

d) <doctype>

The <doctype> tag specifies the document type.
The document type is specified by the Document Type Definition (DTD).
The HTML syntax rules are specified by the file xhtml.dtd file.
Hence, it is mandatory to specify the name of the file as the beginning.
There are 3 types of HTML DTDs and those along with their uses are:

HTML 1.0 Strict: This is used when we need a clean markup code.

HTML 1.0 Traditional: This is used when we want to use HTML features in existing documents

HTML 1.0 Frameset: This is used when we want frames in HTML document.

For example:
```
 <!DOCTYPE html  PUBLIC “-//W3C//DTD XHTML 1.0 Traditional//EN”
 “html://www.w3.org/TR/xhtml/DTD/xhtml.1dtd”>
```
