Ans No. 01(a)Revolutionary developments in computers and information technology have improved our

ability to use large volumes of information and sophisticated decision making techniques

effectively and economically. It has changed the way we work, live and carry out their activities.

We can identify the following trends in types of computer systems and software.

Computers are becoming more powerful in terms of speed of computing, data storage

capacity, and ability to perform very wide variety of functions.

Easier data storage and retrieval capabilities. For example RFID are making it very easy

to capture data automatically.

Better communication capabilities using facilities such as rich multimedia, digital

representation and versatile input/output capabilities.

Global reach of communication with instantaneous transmission of communication

irrespective of distances involved.

Reducing size of computer hardware this includes both, computer processors and data

storage devices.

Falling prices of computer hardware.

Availability of software for ever increasing range of applications, and of progressively

better quality.

Further we discuss more advancement in computer systems:

Trends occurring in major types of computer systems

Touchscreen:A type of display screen that has a touch-sensitive transparent panel covering the screen.

Instead of using a pointing device such as a mouse or light pen, you can use your finger to point

directly to objects on the screen.

Although touch screens provide a natural interface for computer novices, they are

unsatisfactory for most applications because the finger is such a relatively large object. It is

impossible to point accurately to small areas of the screen. In addition, most users find touch

screens tiring to the arms after long use.

WIFI Connectivity:Wi-Fi (also spelled Wi-Fi or Wi-Fi) is a popular technology that allows an electronic device to

exchange data wirelessly (using radio waves) over a computer network, including high-speed

Internet connections. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network



P a g e | 2

(WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE)

802.11 standards”. However, since most modern WLANs are based on these standards, the

term "Wi-Fi" is used in general English as a synonym for "WLAN". Only Wi-Fi products that

complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi

CERTIFIED" trademark.

Wireless Keyboard and Mouse:

For users who work and play on a computer for the majority of their day, the design of a

product, especially a wireless keyboard and mouse, is extremely important. Ergonomically,

Logitech’s MX 5500 wireless keyboard and mouse are excellent. A slight wave in the keyboard

puts your hands at a comfortable angle, and the palm rest supports the lower part of your

hands and wrists. The keyboard can also adjust to different heights and angles depending on

what is most comfortable for the user. It is very thin with a profile of 1.01 inches, and it weighs

only 30.69 ounces, making it easy to pack around. The mouse has a high arch to match thenatural curve of your hand. There are two side buttons, a convenient scroll wheel and thumb

controls as well. The only design flaw we see in this wireless keyboard and mouse combo is the

lack of spill-resistant keys. Competitor keyboards have integrated channels under their keypads

that drain liquid away and avoid penetration into the circuitry.

LCD Monitor’s:

A liquid-crystal display (LCD) is a flat panel display, electronic visual display, or video display

that uses the light modulating properties of liquid crystals. Liquid crystals do not emit lightdirectly.

LCDs are available to display arbitrary images (as in a general-purpose computer display) or

fixed images which can be displayed or hidden, such as preset words, digits, and 7-segment

displays as in a digital clock. They use the same basic technology, except that arbitrary images

are made up of a large number of small pixels, while other displays have larger elements.

LCDs are used in a wide range of applications including computer monitors, televisions,

instrument panels, aircraft cockpit displays, and signage. They are common in consumerdevices such as video players, gaming devices, clocks, watches, calculators, and telephones, and

have replaced cathode ray tube (CRT) displays in most applications. They are available in a

wider range of screen sizes than CRT and plasma displays, and since they do not use phosphors,

they do not suffer image burn-in. LCDs are, however, susceptible to image persistence.

The LCD screen is more energy efficient and can be disposed of more safely than a CRT. Its low

electrical power consumption enables it to be used in battery-powered electronic equipment. It



P a g e | 3

is an electronically modulated optical device made up of any number of segments filled with

liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in

color or monochrome. Liquid crystals were first discovered in 1888. By 2008, worldwide sales of

televisions with LCD screens exceeded annual sales of CRT units; the CRT became obsolete for

most purposes.

Tablet PC:

A tablet computer, or simply tablet, is a one-piece mobile computer. Devices typically offer a

touchscreen, with finger (or stylus) gestures acting as the primary means of control, though

often supplemented by the use of one or more physical context sensitive buttons or the input

from one or more accelerometers; an on-screen, hide able virtual keyboard is generally offered

as the principal means of data input. Available in a variety of sizes, tablets customarily offer a

screen diagonal greater than 7" (18 cm), differentiating themselves through size fromfunctionally similar smart phones or personal digital assistants.

Though generally self-contained a tablet computer may be connected to a physical keyboard

(or other input device), and a number of Hybrids that offer a detachable keyboard have been

marketed since the mid 1990s, as have a number of convertible touchscreen notebook

computers that offer an integrated keyboard that can be hidden by a swivel joint or slide joint,

exposing only the screen for touch operation. Tablets have also appeared in a foldable Booklet

format that offer the user dual-touchscreens, and can be used as a notebook by displaying a

virtual keyboard on one of the displays.

LAPTOP’s:

A laptop computer is a personal computer for mobile use. A laptop has most of the same

components as a desktop computer, including a display, a keyboard, a pointing device such as a

touchpad (also known as a track pad) and/or a pointing stick, and speakers into a single unit. A

laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet

using a rechargeable battery. Laptops are also sometimes called notebook computers,

notebooks, ultra books or netbooks.

Portable computers, originally monochrome CRT-based and developed into the modern

laptops, were originally considered to be a small niche market, mostly for specialized field

applications such as the military, accountants and sales representatives. As portable computers

became smaller, lighter, cheaper, more powerful and as screens became larger and of better

quality, laptops became very widely used for all sorts of purposes

Computer virus

A computer virus is a computer program that can replicate itself and spread from one computer

to another. The term "virus" is also commonly, but erroneously, used to refer to other types of

malware, including but not limited to adware and spyware programs that do not have a

reproductive ability.

Malware includes computer viruses, computer worms, ransom ware, Trojan horses, and key

loggers, most rootkits, spyware, dishonest adware, malicious BHOs and other malicious

software. The majority of active malware threats are usually Trojans or worms rather than

viruses. Malware such as Trojan horses and worms is sometimes confused with viruses, which

are technically different: a worm can exploit security vulnerabilities to spread itself

automatically to other computers through networks, while a Trojan horse is a program that

appears harmless but hides malicious functions. Worms and Trojan horses, like viruses, may

harm a computer system's data or performance. Some viruses and other malware have

symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to

call attention to them. Some viruses do nothing beyond reproducing themselves.

Types of Viruses

Not all computer viruses behave, replicate, or infect the same way. There are several different

categories of viruses and malware. Below I list and discuss some of the most common types of

computer viruses.

Trojan horse:

A Trojan horse program has the appearance of having a useful and desired function. While it

may advertise its activity after launching, this information is not apparent to the user

beforehand. Secretly the program performs other, undesired functions. A Trojan horse neither

replicates nor copies itself, but causes damage or compromises the security of the computer. A

Trojan horse must be sent by someone or carried by another program and may arrive in the

form of a joke program or software of some sort. The malicious functionality of a Trojan Horse

may be anything undesirable for a computer user, including data destruction or compromising a

system by providing a means for another computer to gain access, thus bypassing normal

access controls.



P a g e | 6

Worms:

A worm is a program that makes and facilitates the distribution of copies of itself; for example,

from one disk drive to another, or by copying itself using email or another transport

mechanism. The worm may do damage and compromise the security of the computer. It mayarrive via exploitation of system vulnerability or by clicking on an infected e-mail.

Boot sector Virus:

A virus which attaches itself to the first part of the hard disk that is read by the computer upon

boot up. These are normally spread by floppy disks.

Macro Virus:

Macro viruses are viruses that use another application's macro programming language to

distribute themselves. They infect documents such as MS Word or MS Excel and are typicallyspread to other similar documents.

Memory Resident Viruses:

Memory Resident Viruses reside in a computers volatile memory (RAM). They are initiated

from a virus which runs on the computer and they stay in memory after its initiating program

closes.

Rootkit Virus:

A rootkit virus is an undetectable virus which attempts to allow someone to gain control of acomputer system. The term rootkit comes from the Linux administrator root user. These viruses

are usually installed by Trojans and are normally disguised as operating system files.

Polymorphic Viruses:

A polymorphic virus not only replicates itself by creating multiple files of it, but it also changes

its digital signature every time it replicates. This makes it difficult for less sophisticated antivirus

software to detect.

Logic Bombs/Time Bombs:These are viruses which are programmed to initiate at a specific date or when a specific event

occurs. Some examples are a virus which deletes your photos on Halloween, or a virus which

deletes a database table if a certain employee gets fired.

Ans No. 02(a):Check spelling and grammar automatically

How automatic spelling and grammar checking works and how to turn it on or off.

Notes

There is no option to check spelling while you type in Access, Excel, or Project.

Grammar checking is available only in Outlook and Word.

You can right-click the misspelled word to see suggested corrections.



P a g e | 9

Depending on the Microsoft Office program that you are using, right-clicking a word can give

you other options, such as adding the word to your custom dictionary.

How automatic spelling checking works (Outlook and Word only)

When you check the spelling automatically as you type, you can be more confident that youwon't have to correct many spelling mistakes. Your Microsoft Office program can flag

misspelled words as you work so that you can easily locate them, as in the following example.

You can right-click the misspelled word to see suggested corrections.

On the shortcut menu, a suggested correction might appear. You can also choose to ignore the

error or click About This Sentence to see why the program considers the text to be a mistake.

Turn on or off automatic spelling and grammar checking

Word1. Click the File tab.

2. Under Help, click Options, and then click Proofing.

3. To turn on or off automatic spelling checking and automatic grammar checking for the

currently open document, do the following:

1. Under Exceptions for, click Name of currently open file.

2. Select or clear the Hide spelling errors in this document only and Hide grammar

errors in this document only check boxes.

To turn on or off automatic spelling checking and automatic grammar checking for all

documents that you create from now on, do the following:

1. Under Exceptions for, click All New Documents.

2. Select or clear the Hide spelling errors in this document only and Hide grammar errors

in this document only check boxes.



P a g e | 10

By using a custom dictionaryWhen you use the spelling checker, it compares the words in your document with those in the

main dictionary. The main dictionary contains the most common words, but it might not include

proper names, technical terms, or acronyms. In addition, some words might be capitalized

differently in the main dictionary than in your file. Adding such words or capitalization to acustom dictionary prevents the spelling checker from flagging them as mistakes. You can create

additional custom dictionaries to complement the default dictionary that is included with the

Office for Mac applications. A custom dictionary is useful if, for example, your work relies on a

particular terminology, such as legal terms. Alternatively, you could create a custom dictionary

that includes the names of your work contacts so that you know you're always spelling their

names correctly.

Note any custom dictionary setting that you change in one Office for Mac application affects all

the other applications. For example, you set many of the custom dictionary settings in Word,

and then see the changes the next time you open PowerPoint or Excel.

Do any of the following:

Add a word from your document to a custom dictionary

Create a new custom dictionary in Word

Import a custom dictionary in Word

Add, delete, or edit words in a custom dictionary in Word

Change which custom dictionary to add new words to

Change the language that is associated with a custom dictionary

SmartArt graphicA SmartArt graphic is a visual representation of your information that you can quickly and easily

create, choosing from among many different layouts, to effectively communicate your message

or ideas. To see a video of a user creating SmartArt graphics, go to Community video: Add

illustrations with SmartArt. The examples in the video are shown in Microsoft Office Outlook

2007, but you can create SmartArt graphics in Microsoft Office Excel 2007, Microsoft Office

PowerPoint 2007, and Microsoft Office Word 2007 too.



P a g e | 11

Overview of creating a SmartArt graphic

Most content that is created by using 2007 Microsoft Office system programs is textual, even

though the use of illustrations improves understanding and memory and encourages action.Creating designer-quality illustrations can be challenging, especially if you are not a professional

designer or you cannot afford to hire a professional designer. If you use earlier versions of

Microsoft Office, you can spend a lot of time getting shapes to be the same size and to be

aligned properly, getting your text to look right, and manually formatting the shapes to match

the document's overall style, instead of focusing on your content. With the new 2007 Office

release feature called SmartArt graphics, and other new features such as themes, you can

create designer-quality illustrations with only a few clicks of your mouse.

You can create a SmartArt graphic in Microsoft Office Excel 2007, Microsoft Office PowerPoint2007, Microsoft Office Word 2007, or in an e-mail message in Microsoft Office Outlook 2007.

Although you cannot create a SmartArt graphic in other 2007 Office release programs, you can

copy and paste SmartArt graphics as images into those programs.

Applies only to Microsoft Office PowerPoint 2007

Because Office PowerPoint 2007 presentations often contain slides with bulleted lists, you can

quickly convert slide text to a SmartArt graphic. In addition, you can add animation to your

SmartArt graphic in Office PowerPoint 2007 presentations.

When you create a SmartArt graphic, you are prompted to choose a type of SmartArt graphic,

such as Process, Hierarchy, Cycle, or Relationship. A type is similar to a category of SmartArt

graphic, and each type contains several different layouts. After you choose a layout, it is easy to

change the layout for your SmartArt graphic. Most of your text and other content, colors,

styles, effects, and text formatting are automatically carried over to the new layout.



P a g e | 12

When you select a layout, placeholder text (such as [Text]) is displayed, so that you can see how

your SmartArt graphic looks. Placeholder text is not printed, nor is it displayed during a slide

show. However, the shapes are always displayed and printed, unless you delete them. You can

replace the placeholder text with your own content.

As you add and edit your content in the Text pane, your SmartArt graphic is automatically

updated — shapes are added or removed as needed.

You can also add and remove shapes in your SmartArt graphic to adjust the structure of the

layout. For example, even though the Basic Process layout appears with three shapes, your

process may need only two shapes, or it may need five shapes. As you add or remove shapes

and edit your text, the arrangement of the shapes and the amount of text within those shapes

is updated automatically — maintaining the original design and border of the layout for your

SmartArt graphic.

To quickly add a designer-quality look and polish to your SmartArt graphic, apply a SmartArt

Style to it.

What to consider when you create a SmartArt graphic

Before you create your SmartArt graphic, visualize what type and layout are best for displaying

your data. What do you want to convey with your SmartArt graphic? Do you want a certain

look? Since you can quickly and easily switch layouts, try different layouts (across types) until

you find the one that best illustrates your message. Your graphic should be clear and easy to

follow. Experiment with different types by using the table below as a starting point. The table is

intended to help you get started and is not an exhaustive list.



P a g e | 13

Also, consider the amount of text that you have, because the amount of text often determines

the layout that you use and how many shapes you need in the layout. In general, SmartArt

graphics are most effective when the number of shapes and the amount of text are limited tokey points. Larger amounts of text can distract from the visual appeal of your SmartArt graphic

and make it harder to convey your message visually. However, some layouts, such as Trapezoid

List in the List type, work well with larger amounts of text.

Some layouts for SmartArt graphics contain a fixed number of shapes. For example, the

Counterbalance Arrows layout in the Relationship type is designed to show two opposing ideas

or concepts. Only two shapes can contain text, and the layout cannot be changed to display

more ideas or concepts.

If you need to convey more than two ideas, switch to another layout that has more than two

shapes for text, such as the Basic Pyramid layout in the Pyramid type. Keep in mind that

changing layouts or types can alter the meaning of your information. For example, a layout with

arrows pointing to the right, such as Basic Process in the Process type, has a different meaningfrom a SmartArt graphic with arrows going in a circle, such as Continuous Cycle in the Cycle

type.



P a g e | 14

Create a SmartArt graphic and add text to it

1. On the Insert tab, in the Illustrations group, click SmartArt.

2. In the Choose a SmartArt Graphic dialog box, click the type and layout that you want.

3. Enter your text by doing one of the following:

Click [Text] in the Text pane, and then type your text.

Copy text from another location or program, click [Text] in the Text pane, and

then paste your text.

Notes

If the Text pane is not visible, click the control.

To add text in an arbitrary position close to or on top of your SmartArt graphic, on the

Insert tab, in the Text group, click Text Box to insert a text box. If you want only the text

in your text box to appear, right-click your text box, click Format Shape or Format Text

Box, and then set the text box to have no background color and no border.

Click in a box in the SmartArt graphic, and then type your text. For best results, use this

option after you add all of the boxes that you want.

Add or delete shapes in your SmartArt graphic

1. Click the SmartArt graphic that you want to add another shape to.

2. Click the existing shape that is located closest to where you want to add the new shape.

3. Under SmartArt Tools, on the Design tab, in the Create Graphic group, click the arrow

under Add Shape.



P a g e | 15

If you don't see the SmartArt Tools or Design tabs, make sure that you've selected the SmartArt

graphic.

4. Do one of the following:

To insert a circle after the selected shape, that will overlap the selected shape,

click Add Shape After.

To insert a shape before the selected circle, that will overlap the selected shape,

click Add Shape Before.

Notes

To add a shape from the Text pane, click an existing shape, move your cursor before or

after the text where you want to add the shape, and then press ENTER.

To delete a shape from your SmartArt graphic, click the shape you want to delete, and

then press DELETE. To delete your entire SmartArt graphic, click the border of your

SmartArt graphic, and then press DELETE.

Apply a SmartArt Style to a SmartArt graphic

A SmartArt Style is a combination of various effects, such as line style, bevel, or 3-D, that you

can apply to the shapes in your SmartArt graphic to create a unique and professionally designed

look.1. Click your SmartArt graphic.

2. Under SmartArt Tools, on the Design tab, in the SmartArt Styles group, click the

SmartArt Style that you want.

Ans No. 03(i)Insert and overtype modes

If you have made the Status bar visible it will display whether you are in insert or overtype

mode as you type. If you are in insert mode, you will see the word "Insert" in the Status bar andany text you paste in will push aside text on either side of the cursor. If you are in overtype

mode, you will see the word "Overwrite" in the Status bar and any text you paste in will

overwrite existing text to the right of the cursor.



P a g e | 16

You can also tell which typing mode you are in by examining the article cursor. Clicking any text

in insert mode displays the cursor as a thin vertical line ("|") between letters, whereas in

overwrite mode it becomes a blue bar highlighting the letter to the right of the cursor like this.

Pressing the Insert key toggles between the two modes.

That’s all changed in Word 2007. By default, the *Insert+ key does not toggle Overtype mode.

That change is probably confusing to people who are use to that routine. You can still use

[Insert], but you have to flag a setting, as follows:

1. Click the Office button.

2. Click the Word Options button.

3. Choose Advanced in the left pane.

4. In the Editing Options section, check the Use the Insert Key to Control Overtype Mode

option.

5. Click OK

If you want to work in Overtype mode solely, check the Use Overtype Mode (step 4). I’m still

uncertain as to why Word uses this particular hierarchy. Usually, a sub option is available only if

the main option is checked, but not so with these two.

Perhaps it’s best to just forget the old ways. Don’t even bother with *Insert+. Instead, right-click

the Status bars and checks Overtype. Doing so displays the Overtype/Insert indicator. Then,

simply click the indicator to switch between the two modes. It’s definitely a change for the

better… if you can find it!

Ans No. 03(ii)Difference between auto text and auto correct in Microsoft Word?

Word's AutoText feature allows users to store any amount of text and graphics for re-use in

other documents. This is typically referred to as boilerplate text.

The AutoCorrect feature automatically replaces text as you type. This is really intended to

correct common mistakes. For example, you type 'teh', Word change it to 'the'. That's

AutoCorrect.

You can set up your own AutoCorrect entries and in that way replace one string of text with

another.

People often use AutoCorrect to insert boilerplate text instead of using AutoText. For example,

they type P1 and Word automatically replaces it with the text the user has told Word is the

'correction' to apply when that string is typed.

However, an AutoCorrect replacement string is limited to something like 256 characters thus

limiting its effective use in relation to boilerplate type text. It is also irritating if you actually

want to use the string of characters, such as P1, in text.

An obvious example of this is that by default Word replaces (c) with the copyright symbol.

Useful but annoying if you really want (c) in your text.

As far as I am aware, it is not possible to print a list of AutoCorrect entries, whereas it is easy to

print a list of AutoText entries.

AutoText entries can also be stored in a specific Word template. For example, you may want a

series of paragraphs to create a Will but would not need those paragraphs for any other reason.By storing the entries in a template upon which you base wills, they will not be available when

working on any other document type.

It is easy to move AutoText entries between templates & to copy them to other users whereas

it is not as easy to do so with AutoCorrect entries.

Ans No. 03(iii)Soft Page Breakup & Hard Page Breakup

In Microsoft Word there has always been two key page breaks types, a soft page break and a

hard page break and they both have different roles. I want to take some time to explain the

difference between the two.

A soft page break is inserted by Microsoft Word when you get to the end of the page and the

program can no longer fit any more text on the page. How much can be fit on the page is

dictated by Page Layout elements such as page size, orientation, margins and font size and

type.

The soft page break cannot be removed by the user and as such we really don’t have a lot of

control over where it is placed on the page except for modifying the Page Layout elements I

talked about before.

A Hard Page break is different; you can insert a hard page break at anytime into a document.

The hard page break tells the program that this is where you want to end the text on this page

and then start a new page.

To insert a hard page break you can do this in Microsoft Office 2003 by using the Insert menu

and then choosing break from the drop down menu. In Microsoft Office 2007 and 2010 you can

choose the same option from the ribbon. The easiest way to insert a hard page break is to use

the shortcut keys and the shortcut key for a hard page break is ….. *Ctrl+ + [Enter]

A soft break is a break at the end of a line or a page that occurs when the program word-wraps

or advances pages automatically. A hard break (anywhere in a line or a page) is forced by the

program user, who uses a keystroke to force the break at a specific point -- the keystrokeembeds a hard-break code.

The location of a soft break adjusts automatically with a change in the margins or the line-

lengths or the number of lines. The hard break remains in its original location unless the

operator deliberately removes it or relocates it.

Ans No. 03(iv)Difference between Workbook & Worksheet

Worksheet

A worksheet (also known as a spreadsheet) is a collection of cells on a single “sheet” where you

actually keep and manipulate the data.

An Excel worksheet is a single spreadsheet that contains cells organized by rows and columns. A

worksheet begins with row number one and column A. Each cell can contain a number, text or

formula. A cell can also reference another cell in the same worksheet, the same workbook or a

different workbook. In Excel 2010, the maximum size of a worksheet is 1,048,576 rows by

16,384 columns.

Workbook

A workbook is the MS Excel file in which you enter and store related data.

A workbook is an Excel file that contains one or more worksheets. Each of the workbook &

worksheets are in separate tabs on the bottom of the Excel window. By default, a new Excel

workbook will contain three worksheets. You can switch between worksheets by clicking on the

worksheet & tab on the bottom of the Excel window. In Excel 2010 the number of worksheets

in workbooks is limited only by your computer available memory.

Ans No. 03(v)IF Function & VLOOKUP Function

Searches for a value in the first column of a table array and returns a value in the same row

from another column in the table array.

The V in VLOOKUP stands for vertical. Use VLOOKUP instead of HLOOKUP when your

comparison values are located in a column to the left of the data that you want to find.

Syntax

VLOOKUP (lookup_value, table_array, col_index_num, range_lookup)

Lookup_value The value to search in the first column of the table array. Lookup_value can

be a value or a reference. If lookup_value is smaller than the smallest value in the first column

of table_array, VLOOKUP returns the #N/A error value.



P a g e | 20

Table array Two or more columns of data. Use a reference to a range or a range name. The

values in the first column of table_array are the values searched by lookup_value. These values

can be text, numbers, or logical values. Uppercase and lowercase texts are equivalent.

Col_index_num The column number in table_array from which the matching value must be

returned. A col_index_num of 1 returns the value in the first column in table_array; a

col_index_num of 2 returns the value in the second column in table_array, and so on. If

col_index_num is:

IF Function

The Excel IF function adds flexibility to your spreadsheets by introducing decision making. It

does this by testing a specified condition in your spreadsheet to see if it is true or false.

If the condition is true, the function will carry out one action. If the condition is false, it will

carry out a different action.

The function allows you to specify what actions it should carry out depending on whether the

condition is true or not. These actions can include executing a formula, inserting a text

statement, or leaving the target cell blank.

How to create a table of contents by marking text in WordOne of the most common features of professional documents is the table of contents (TOC).

Microsoft Word makes the creation of a TOC easier by allowing you the option of creating a

TOC without using styles and by allowing you to mark a single word or group of words in a

particular body of text and add that information to the TOC.

A TOC can be generated by using the Lead-in Emphasis feature to apply heading styles to any

lead-in text (the first word or words in a paragraph or sentence). By using the Lead-in Emphasis

feature, you can create paragraphs where the first portion of the paragraph is formatted with a

heading style and appears in the TOC, but the rest of the paragraph is normal text and does not

appear in the TOC. This article describes how to use this new feature to create a TOC.

Create Table of Contents

In Word, you can create a TOC based on a portion of the text in a paragraph without including

the whole paragraph. You can mark text by using the Lead-in Emphasis feature with heading

styles to include the text in a TOC.

To insert a table of contents, follow these steps:

1. Start Word, and then open your document.

2. Click an empty paragraph where you want to insert the TOC.

3. On the Insert menu, point to Reference, and then click Index and Tables.

Note In Microsoft Office Word 2007 or in Word 2010, click Table of Contents in the

Table of Contents group on the References tab. Then, click Insert Table of Contents.

4. Click the Table of Contents tab, and then click Show Outlining Toolbar.

Note In Word 2007 or in Word 2010, skip this step.

5. In the Index and Tables dialog box, select the options that you want to apply to your

TOC, and then click OK.

d. To mark the index entry, click Mark. To mark all occurrences of this text in the

e. To mark additional index entries, select the text, click in the Mark Index Entry

dialog box, and then repeat steps 3 through 5.

2.

Click where you want to insert the finished index.3. To make sure that the document is paginated correctly, you need to hide field codes and

Ans No. 05(ii):Data can be imported from a web query into an MS Excel workbook

Excel makes it easy to extract table data from a Web page — but to be of use in a worksheet;

you will need to convert the text tables into columns. For example, say you need to chart U.S.

GDP data from 2002 through 2006. First, you would use a Web query to import the data from

the Web. Then, you’d extract the data into two separate columns. Follow these steps:

1.

Open a blank worksheet.2. Go to Data | Import External Data and then click New Web Query. In Excel 2007,

click the Data tab, click Get External Data, and then click From Web.

3. Enter the Web page URL http://forecasts.org/data/index.htm (Figure A).

Calculating Loan Payments with Excel 2010's PMT FunctionExcel 2010's PMT function calculates the periodic payment for an annuity, assuming a stream of

equal payments and a constant rate of interest. The PMT function uses the following syntax:

=PMT (rate, nper, pv, [fv], [type])

As with the other common financial functions, rate is the interest rate per period, nper is the

number of periods, pv is the present value or the amount the future payments are worth

presently, fv is the future value or cash balance that you want after the last payment is made

(Excel assumes a future value of zero when you omit this optional argument as you would when

calculating loan payments), and type is the value 0 for payments made at the end of the periodor the value 1 for payments made at the beginning of the period (if you omit the optional type

argument, Excel assumes that the payment is made at the end of the period).

The PMT function is often used to calculate the payment for mortgage loans that have a fixed

rate of interest. The following figure shows a sample worksheet that contains a table using the



P a g e | 31

PMT function below to calculate loan payments for a range of interest rates (from 4.5 percent

to 5.75 percent) and principals ($350,000 to $359,000).

=PMT (B$6/12, $B$4*12, $A7)

The table uses the initial principal that you enter in cell B2, copies it to cell A7, and then

increases it by $1,000 in the range A8:A16. The table uses the initial interest rate that you enter

in cell B3, copies to cell B6, and then increases this initial rate by 1/4 of a percent in the range

C6:G6. (The term in years in cell B4 is a constant factor that is used in the entire loan payment

table. This means that every cell in range A6:G16 contains a formula except cell A6.)
