v) Rounddown(3.29763,3)
Question 8
Differentiate between Absolute & relative cell referencing with the help of suitable
assignment.
Absolute and Relative Cell References
In Excel, when you enter a cell into a formula it will be a relative reference.
Consider the example below where we enter x and then want y = x2.
In cell B4, we entered the formula as
=A4^2. This is a relative reference when we drag the lower right hand corner of B4,
the cursor changes to a solid black plus sign and allows us to drag the formula down the
column. As we drag, the relative reference changes to A5, A6, A7, etc.

24. Now suppose we wanted to enter the formula y = ax2 and wanted to be able to
vary the value of the constant “a” in the formula. In cell B4, we entered the
formula as =$E$2*A4^2. The reference to cell E4, where the value is set to equal
2, is an absolute reference. For an absolute cell reference, you place a dollar sign
in front of the column letter and row number (if you press the F4 key after
entering the relative cell reference it will add the absolute reference). Now when
we drag the formula down the column, the absolute cell reference stays the same,
while the relative reference changes to use the correct value from column A.
Absolute cell references are going to be used with any fixed cell reference
in a formula. Realize that you can click on the cell you want in a formula
instead of typing the reference.
Mixed cell references are also possible to lock the column or the row only.
Question 9
Type the following data in MS_Excel:
A B C D E
1 Name of employee Basic Salary(Rs) DA HRA Total
salary
2 Ankit 18000
3 Ashima 9000
4 Raman 6500
5 Aman 11000
The employees are paid Dearness Allowance(DA) as per the following rules:-
If Basic Salary<10,000 then DA is paid @ 10% of Basic Salary
If Basic Salary>10,000 then DA is paid @ 12% of Basic Salary
The employees are paid House Rent Allowance(HRA) as per the following rules:-

25. All employess are paid House Rent Allowance(HRA) @12%subject to minimum amount
of Rs. 5000.
Write an appropriate formula in cell C2 to compute the DA,HRA in cell D2 and total
salary (Basic salary+DA+HRA) in cell E2.

28. HTML
1. Define HTML.
HTML (Hypertext Markup Language) is the set of markup symbols or codes inserted in a
file intended for display on a World Wide Web browser page. The markup tells the Web
browser how to display a Web page's words and images for the user. Each individual
markup code is referred to as an element (but many people also refer to it as a tag). Some
elements come in pairs that indicate when some display effect is to begin and when it is
to end.
2. List Basic HTML Tags and explain each tag with syntax.
Basic HTML tags are:
<html>
<body>
<head>
<title>
<h1>
<p>
<br>
 The text between <html> and </html> describes an HTML document. The HTML
document itself begins with <html> and ends with </html>.
The visible part of the HTML document is between <body> and </body>. The
text between <body> and </body> describes the visible page content
 The text between <head> and </head> provides information about the document.
 The text between <title> and </title> provides a title for the document.
 The text between <h1> and </h1> describes a heading.
 The text between <p> and </p> describes a paragraph.
 The tag of <br> represents a line break. It also does not have a closing tag. The
optional argument CLEAR in conjunction with aligned images is useful.

29. Example:
<IMG src="filename" ALIGN=right>
The text that is to be next to the image.
<br CLEAR="RIGHT">
after a right-aligned image.
3. Create a webpage with title as your name, and also insert an image and also write
some content on the webpage in red color in italics.

30. 4. Create a webpage with title as your name, and also insert a table of three columns
with some data and also write some content on the webpage in blue color in bold and
underlined and in different sizes.

31. 5. What are frames? How do they help in organizing contents of a web page?
A frame is a part of a web page or browser window which displays content independent of
its container, with the ability to load content independently. The HTML or media elements that
go in a frame may or may not come from the same web site as the other elements of content on
display. In HTML, a frameset is a group of named frames to which web pages and media can be
directed; an I frame provides for a frame to be placed inside the body of a document. Since the
early 2000s, the use of framesets has increasingly been considered obsolete due to usability and
accessibility concerns, and the feature has been removed from the HTML5 standard.
Using tables and frames on your Web page helps you present information to your site visitors in
an organized manner. Tables are a layout tool for data tables on Web pages, but the table
capability for Web pages has long been used to control the layout of the entire page.
Designers make the cells of a table very large, and put large graphics or whole blocks of text in
them. You can even resize tables automatically to accommodate various sizes of Web-browser
windows — at least up to a point.
Whether and how to use tables was, for a long time, one of the most controversial topics in Web-
page design.
Frames are more powerful layout devices than tables, but they have fallen into disfavor. They
allow separate parts of the Web-browser window to be updated and scrolled separately.
However, they produce odd effects; users seem to prefer one unified window to separate “panes”
within a window.
When designing your own Web page, there are so many different elements that you have to
adjust in table-based page design that you need to invest a lot of time and energy to learn how to
use tables effectively for layout purposes. And then a whole other set of issues arises about
making sure your table-based page design works well on most or all current computer systems
and Web-browser setups that are in use.
To create your own tables, you can get started by using the Insert→ Table command in Coffee
Cup. However, you really need a more advanced tool to work effectively with tables in your
Web pages — something like Microsoft FrontPage or Dreamweaver, both of which give you
more direct control over specific options. Of course, your other option is to start doing a lot of
experimenting in HTML until you learn how to get things just how you want them.
Frames divide a Web page into separate areas which you can then update individually. For
example, you can click a link in a frame in the bottom half of a Web page and update it with new
content while the other frame stays unchanged. This seems like a powerful capability. However,
frames are less popular than tables because frames are hard to create and manage. But advanced
With frames, the trouble comes with the “useful” part; users have a hard time using framed Web
pages.

32. For example, when browsing a framed page, users sometimes have difficulty finding where the
cursor is. If the user moves the scroll bar, which frame scrolls? Also, going forward and
backward in a frame is different from going forward and backward in the overall Web page, so
users may get lost easily. And printing a framed page properly requires extra steps.
Finally, frames create a functional problem or two. When users resize a browser window, framed
pages don’t always resize correctly. And designing a framed page to work well for various
monitor sizes is even harder than correctly designing pages with tables embedded in them.
