Question No: 01
(a) What are the various types of computers? Differentiate each type.
Answer)
ComputerAn electronic device for storing and processing data, typically in binary form,
according to instructions given to it in a variable program.
Classification of Computers
Based on the operational principle of computers, they are categorized as analog,
digital and hybrid computers.
Analog Computers: These are almost extinct
today. These are different from a digital computer because an analog computer can
perform several mathematical operations simultaneously. It uses continuous
variables for mathematical operations and utilizes mechanical or electrical energy.
Digital Computers: They use digital circuits and are designed to operate on two
states, namely bits 0 and 1. They are analogous to states ON and OFF. Data on these
computers is represented as a series of 0s and 1s. Digital computers are suitable for
complex computation and have higher processing speeds.
Hybrid Computers: These computers are a combination of both digital and analog
computers. In this type of computers, the digital segments perform process control
by conversion of analog signals to digital ones.
This was the classification of computers based on their style of functioning.Following is a classification of the different types of computers based on their sizes
and processing powers.

Mainframe Computers: Large organizations use mainframes for highly critical
applications such as bulk data processing and ERP. Most of the mainframe computers
have capacities to host multiple operating systems and operate as a number of
virtual machines. They can substitute for several small servers.
Microcomputers: A computer with a microprocessor and its central processing unit is
known as a microcomputer. They do not occupy space as much as mainframes do.
When supplemented with a keyboard and a mouse, microcomputers can be called
personal computers.
Personal computers come in different forms such as desktops, laptops and personal
digital assistants. Let us look at each of these
types of computers.
Desktops: A desktop is intended to be used on a single location. The spare parts of a
desktop computer are readily available at relatively lower costs. Power consumption
is not as critical as that in laptops. Desktops are widely popular for daily use in the
workplace and households.
Laptops: Similar in operation to desktops, laptop computers are miniaturized and
optimized for mobile use. Laptops run on a single battery or an external adapter
that charges the computer batteries. They are enabled with an inbuilt keyboard,
touch pad acting as a mouse and a liquid crystal display.
Notebooks: They fall in the category of laptops, but are inexpensive and relatively
smaller in size. They had a smaller feature set and lesser capacities in comparison to
regular laptops, at the time they came into the market. But with passing time,
notebooks too began featuring almost everything that notebooks had. By the end of2008, notebooks had begun to overtake notebooks in terms of market share and
sales.
Personal Digital Assistants (PDAs): It is a handheld computer and popularly known
as a palmtop. It has a touch screen and a memory card for storage of data. PDAs can
also be used as portable audio players, web browsers and smart phones. Most of
them can access the Internet by means of Bluetooth or Wi-Fi communication.

Minicomputers: In terms of size and processing capacity, minicomputers lie in
between mainframes and microcomputers. Minicomputers are also called mid-range
systems or workstations. The term began to be popularly used in the 1960s to refer
to relatively smaller third generation computers.
Servers: They are computers designed to provide services to client machines in a
computer network. They have larger storage capacities and powerful processors.
Running on them are programs that serve client requests and allocate resources like
memory and time to client machines. Usually they are very large in size, as they
have large processors and many hard drives. They are designed to be fail-safe and
resistant to crash.
Supercomputers: The highly calculation-intensive tasks can be effectively performed
by means of supercomputers. Quantum physics, mechanics, weather forecasting,
molecular theory are best studied by means of supercomputers. Their ability of
parallel processing and their well-designed memory hierarchy give the
supercomputers, large transaction processing powers.Wearable Computers: A record-setting step in the evolution of computers was the
creation of wearable computers. These computers can be worn on the body and are
often used in the study of behavior modeling and human health. Military and health
professionals have incorporated wearable computers into their daily routine, as a
part of such studies. When the users' hands and sensory organs are engaged in other
activities, wearable computers are of great help in tracking human actions.
Wearable computers do not have to be turned on and off and remain in operation
without user intervention.
Tablet Computers: Tablets are mobile computers that are very handy to use. They
use the touch screen technology. Tablets come with an onscreen keyboard or use a
stylus or a digital pen. Apple's iPad redefined the class of tablet computers.

Question No: 01
(b) How Windows Vista is different from previous versions of Windows?
Explain in detail.
Answer)
A HISTORY OF WINDOWS
19751981: Microsoftboots up
Getting started: Microsoft co-founders Paul Allen (left) and Bill Gates
Its the 1970s. At work, we rely on typewriters. If we need to copy a document, we
likely use a mimeograph or carbon paper. Few have heard of microcomputers, buttwo young computer enthusiasts, Bill Gates and Paul Allen, see that personal
computing is a path to the future.
In 1975, Gates and Allen form a partnership called Microsoft. Like most start-
ups, Microsoft begins small, but has a huge visiona computer on every desktop and
in every home. During the next years, Microsoft begins to change the ways we work.
Microsoft focused on a new operating systemthe software that manages, or runs,
the computer hardware and also serves to bridge the gap between the computer
hardware and programs, such as a word processor. Its the foundation on which
computer programs can run. They name their new operating system "MS-DOS."

Windows 1.0. Now, rather than typing MS-DOS commands, you just move a mouse to
point and click your way through screens, or windows.
1 98 7 19 92 : W in do ws 2 .0 2 .1 1 Mo re w in do ws ,m or e s p eed
On December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and
expanded memory. Windows 2.0 is designed for the Intel 286 processor. When the
Intel 386 processor is released, Windows/386 soon follows to take advantage of its
extended memory capabilities. Subsequent Windows releases continue to improve
the speed, reliability, and usability of the PC.
1 9 9 0 1 9 9 4 : Wi nd ows 3 .0 Wi nd ows N T Get t i n g
t h e g r a p h i c sThe popularity ofWindows 3.0grows with the release of a newWindows software
development kit (SDK), which helps software developers focus more on writingprograms and less on writing device drivers.
Windows NT
When Windows NT releases on July 27, 1993, Microsoft meets an important
milestone: the completion of a project begun in the late 1980s to build an advanced
new operating system from scratch. "Windows NT represents nothing less than a
fundamental change in the way that companies can address their business computing
requirements," Bill Gates says at its release.

RibbonThe Ribbon is designed to help you quickly find the commands that you need to
complete a task. Commands are organized in logical groups, which are collected
together under tabs. Each tab relates to a type of activity, such as writing or laying
out a page. To reduce clutter, some tabs are shown only when needed. For example,
the Picture Tools tab is shown only when a picture is selected.
RulerThe horizontal and vertical rulers in Word are often used to align text, graphics,
tables, and other elements in a document.
To view the horizontal ruler across the top of your Word document and the vertical

Just like everything else in Word, your table can be formatted with different fonts,
colors, line styles, and more.
Changing the line weight, color, and style
Most tables have some kind of grid. But in Word, you can keep the table and remove
the grid, change the grid line style to some other type, and change the color of the
lines altogether.
On the toolbar, the four options to the right of the Eraser button handle the line
styles in your table.

Changing the alignment in each cell
You can also change the position of the text in each individual cell in your table. Insome cells, you might want the text centered both horizontally and vertically, while
in another cell, you might want the text aligned at the bottom-right corner. This is
where the cell alignment options come in

This shows you each alignment option in action... along with a couple of unique border styles.
Distribute rows and columns
Are you a neat freak? Or do you just want to make sure that your table looksprofessional? One way you can do that is to make sure your rows and columns are
sized appropriately. For example, if you're showing monthly budget information,
your column widths for each month should look the same rather than being all
different sizes. Take a look at Figure to see what I mean.
It's actually easy to make your table look neat: Use the Distribute Rows evenly and
Distribute Columns Evenly buttons on the toolbar
These buttons make it easy for you to make your rows and columns equal in width.

Let's suppose you want to make your month columns equal in width. Select the
columns with month headings and then click the Distribute Columns Evenly button
(the second button). You can do the same thing for the rows using the Distribute
Rows Evenly button.
You can also manually change the width of a column or the height of a row . When you're in
your table, take a look at both your horizontal and your vertical ruler bars. Each one is broken up
with a control that just happens to be at the break point for each row and column.
The width and height controls provide you with a place to change how tall your rows are and
how wide your columns appear.
When you move your mouse over one of these controls, it changes into a line with
two arrows signifying that if you click and drag the control, you can change the
width of a column or height of a row.

want to divide the text into columns. Use paragraph marks to indicate where
you want to begin a new row.

first word to create a two-column table.

Question No. 3
b) How to change one column of text to two columns, format both
columns, and insert a column break? Explain.
Answer)
Use Columns in Microsoft Word
Give your business newsletters, manuals and brochures a designer look by arranging
the text in them in a columnar layout. The shorter lines and punchierlook of a two-
column layout maximizes the use of space on the page and aidsreadability.
Benefits of Using Columns
When you lay out page text in columns you will generally fit a little more text on the
page than if you laid it out so the lines stretch full width of the page. The shorter
lines of text are also easier to read, as the reader's eye doesn't need to travel so far
across the page before returning to read the next line of text. A document laid out
in columns can look more approachable too, as there is white space within the page,
which offers readers a place to rest their eyes.

To format an entire document in columns, choose Format >Columns and select the
number of columns to create. If you choose Two, the document will be laid out in
two equal size columns arranged between the current page margins.
In most cases, you wont format the entire document in columns, just part of it, suchas everything below the heading and introductory paragraph. To do this select only
the text you want to place in columns and choose Format > Columns. Select the
number of columns two is a good choice for a standard letter size page.
TheApply To dropdown list will show Selected Text indicating that only the text you
have selected will convert to columns. To add a line between the columns check
the Line Between checkbox and click OK.
The text in the columns will snake around the page similar to print in a newspaper.
It will fill the first column on the page and then the second column. If you have moretext than can fit on a single page it will scroll over to the first column on the next
page and so on.
Managing the Last Page
If you have a long document formatted into columns, you may find that the last page
is unbalanced, and that the text fills only part of one column. If you prefer the
columns to be even, click after the last piece of text on the page and
choose Insert > Break, and from the Section Break options choose Continuous and
click OK. This evens out the text dividing it evenly to fill the two columns on thepage.
Converting Columns to Text

If you have some text in your document thats laid out in columns but you want it to
stretch across the full page, you can undo the columns. To do this, select the text
and choose Format > Columns, select One column and click OK. This returns the
selected text to a single page-wide column.
When you convert text to columns or back to regular page-wide text, Word inserts
continuous-section breaks into the document each time the column formatting
changes. You can see these section breaks by clicking the Show/Hide button on the
toolbar.
Starting a New Column
If you are typing text in a column and if you want to start a new one before you have
completely filled the first, you can insert a column break. To do this, click after the
last piece of text that you want to appear in the current column and
choose Insert > Break > Column Break and click OK. This moves the following text to
the top of the next column even though you havent yet filled the previous column.
Adding Images and Objects
When you add an image or textbox to a document, you can choose to place it in a
column so that it moves with the text in the column or keep it independent of the
text so that it remains in place as the rest of the text moves around it. Heres
how: click the image or text box and choose Format > Picture or Format >TextBox.

anywhere on the page.
Text Formatting Options
When you are working with columns of text, you will find that left-justified text andheadings generally looks neater than fully justified text and centered headings. If
you format text as fully justified, you will often see unsightly rivers of white space
because the text will be stretched to fill the space between the column margins. You
can reduce this effect if you hyphenate the text to do this,
choose Tools > Language >Hyphenation and select theAutomatically Hyphenate
document checkbox.
You will also find that bullet points and numbering look best left aligned in columns
of text so the bullets or numbers are flush with the left margin of the column
instead of inset in from the margin.

Question No. 4) Explain the terms used in MS Excel: absolute cell
reference, relative cell reference, arithmetic operator, pie chart,
data series, constant value, rounding, worksheet grid, sheet tabs,
and vertical window split box.
Answer)
Absolute Cell Reference
In Excel and other spreadsheets, an absolute cell reference identifies the location
a cell or group of cells.
Cell references are used informulas, functions, charts , and other Excel commands.
An absolute cell reference consists of the column letter andrownumber surrounded
by dollar signs ($).
Relative Cell Reference
In Excel and other spreadsheets, a relative cell reference identifies the location of
a cell or group of cells.
Cell references are used informulas, functions, charts , and other Excel commands.
By default, a spreadsheet cell reference is relative. What this means is that as a
formula orfunction is copied and pasted to other cells, the cell references in the
formula or function change to reflect the function's new location.
Arithmetic Operators
An arithmetic operator is the symbol or sign that represents a mathematicaloperation in an Excel spreadsheet formula.
The arithmetic operators used in Excelformulas are similar to the ones we use in
math class.
Subtraction - minus sign (- )
Addition - plus sign (+ )
Division - forward slash (/ )
Multiplication - asterisk (*)
Exponentiation - caret ( )
If more than one operator is used in a formula, there is a specific order of
operations that Excel follows in deciding which mathematical operation occurs first.
Excel Pie Chart
Pie charts, or circle graphs as they are sometimes known, are used to show
percentages.

Question: I'm thinking of starting a store in the local mall to sell gourmet lemonade.Before opening the store, Im curious about how my profit, revenue, and variable
costs will depend on the price I charge and the unit cost.
Most worksheet models contain assumptions about certain parameters or inputs to
the model. In our lemonade example, the inputs would include:
The price for which a glass of lemonade is sold.
The variable cost of producing a glass of lemonade.
The sensitivity of demand for lemonade to price charged.
The annual fixed cost of running a lemonade stand.
Based on input assumptions, we can compute outputs of interest. For the lemonade
example, the outputs of interest might include:
Annual profit
Annual revenue
Annual variable cost
Despite best intentions, assumptions about input values can be in error. For
example, our best guess about the variable cost of producing a glass of lemonademight be $0.45, but it's possible that our assumption will be in error. Sensitivity
analysis determines how a spreadsheet's outputs vary in response to changes to its
inputs. For example, we might want to see how a change in product price affects
yearly profit, revenue, and variable cost. A data table in Office Excel 2007 makes it
easy to vary one or two inputs and perform a sensitivity analysis. With a one-way
data table, you can determine how changing one input will change any number of

outputs. With a two-way data table, you can determine how changing two inputs will
change a single output. Our three examples will show how easy it is to use a data
table and obtain meaningful sensitivity results.
The work required for this analysis is in the file shown in Figures 1, 2, and 4. Our
input assumptions are given in the range D1:D4. We're assuming that annual demand
for lemonade (see the formula in cell D2) equals 650009000*price. I've created the
names in C1:C7 to correspond to cells D1:D7.
I computed annual revenue in cell D5 with the formula demand*price. In cell D6, I
computed the annual variable cost with the formula unit_cost*demand. Finally, in
cell D7, I computed profit by using the formula revenuefixed_costvariable_cost.
Figure 1 The inputs that change the profitability of a lemonade store
Suppose that I want to know how changes in price (for example, from $1.00 through
$4.00 in $0.25 increments) affect annual profit, revenue, and variable cost. Because
we're changing only one input, a one-way data table will solve our problem. The data
table is shown in Figure 2.
To set up a one-way data table, begin by listing input values in a column. I listed the
prices of interest (ranging from $1.00 through $4.00 in $0.25 increments) in the
range C11:C23. Next, I moved over one column and up one row from the list of input
values, and there I listed the formulas we want a data table to calculate. I entered
the formula for profit in cell D10, the formula for revenue in cell E10, and the
formula for variable cost in cell F10.
Now select the table range (C10:F23). The table range begins one row above the firstinput; its last row is the row containing the last input value. The first column in the
table range is the column containing the inputs; its last column is the last column
containing an output. After selecting the table range, display the Data tab of the
Ribbon. In the Data Tools group, click What-If Analysis, and then click Data Table.
Now fill in the Data Table dialog box as shown in Figure 3.

As the column input cell, use the cell in which you want the listed inputs that is,

Because the listed inputs are prices, I chose D1 as the column input cell. After
clicking OK, Excel creates the one-way data table shown in Figure 4.

Figure 4 One-way data table with varying prices
In the range D11:F11, profit, revenue, and variable cost are computed for a price of
$1.00. In cells D12:F12, profit, revenue, and variable cost are computed for a price
of $1.25, and on through the range of prices. The profit-maximizing price among alllisted prices is $3.75. A price of $3.75 would produce an annual profit of $58,125.00,
annual revenue of $117,187.50, and an annual variable cost of $14,062.50.
Suppose I want to determine how annual profit varies as price varies from $1.50
through $5.00 (in $0.25 increments) and unit variable cost varies from $0.30 through
$0.60 (in $0.05 increments).
Because we're changing two inputs, we need a two-way data table. (See Figure 5.) I
list the values for one input down the first column of the table range (I'm using the
range H11:H25 for the price values), and the values for the other input in the firstrow of the table range. (In this example, the range I10:O10 holds the list of variable
cost values.) A two-way data table can have only one output cell, and the formula
for the output must be placed in the upper-left corner of the table range.
Therefore, I placed the profit formula in cell H10.
Figure 5 A two-way data table showing profit as a function of price and unit
variable cost
I select the table range (cells H10:O25), and display the Data tab. In the DataToolsgroup, click What-If Analysis, and then click Data Table. Cell D1 (price) is the
column input cell, and cell D3 (unit variable cost) is the row input cell. This ensures
that the values in the first column of the table range are used as prices, and the
values in the first row of the table range are used as unit variable costs. After
clicking OK, we see the two-way data table shown in Figure 5. As an example, in cell
K19, when we charge $3.50 and the unit variable cost is $0.40, our annual profit

equals $58,850.00. For each unit cost, I've highlighted the profit-maximizing price.
Note that as the unit cost increases, the profit-maximizing price increases as we pass
on some of the cost increase to our customers. Of course, we can only guarantee that
the profit-maximizing price in the data table is within $0.25 of the actual profit-
maximizing price.
Here are some other notes on this problem:
As you change input values in a worksheet, the values calculated by a data
table change, too. For example, if we increased fixed cost by $10,000, all
profit numbers in the data table would be reduced by $10,000.
You can't delete or edit a portion of a data table. If you want to save the
values in a data table, select the table range, copy the values, and then right-
click and select Paste Special. Then choose Values from the Paste
Special menu. If you take this step, however, changes to your worksheet
inputs will no longer cause the data table calculations to update.
When setting up a two-way data table, be careful not to mix up your row and
column input cells. A mix-up will cause nonsensical results.
Most people set their worksheet calculation mode to Automatic. With this
setting, any change in your worksheet will cause all your data tables to be
recalculated. Usually, you want this, but if your data tables are large,
automatic recalculation can be incredibly slow. If the constant recalculation
of data tables is slowing your work down, click theMicrosoft Office Button,
click Excel Options, and then click the Formulas tab. Then select Automatic
Except For Data Tables. WhenAutomatic Except For Data Tables isselected, all your data tables recalculate only when you press the F9
(recalculation) key. Alternatively, you can click the Calculation Options
button (in the Calculation group on the Formulas tab), and then click
Automatic Except For Data Tables.
