at homes for maintaining accounts, pay bills, track personal income and
expenses, etc. Computers also serve as a useful tool for communication.
With today’s technology not only messages but even voice, sound, video
and graphics can be transmitted to any corner of the world. b. The basic organization of a computer system can be understood with the
help of a block diagram given below: i. Input Unit: Whatever data we enter into the computer is called input.
The data or instruction entered with the help of different Input devices
is accepted by the input unit that converts them into the acceptable
form and supplied to the computer system for further processing.
4
ii. System Unit: The box like case stands near or placed under the
monitor is called system unit. Inside the system unit the processing is
completed for the data entered to convert it into information through
a processor with the help of a CPU.
iii. After the processing, the information is displayed for the user with the
help of output unit like monitor or printer.
iv. The process of saving data and information for future use is performed
with the help of different storage devices like hard disk, CD-ROM or a
pen drive.
c. A touch screen is a touch-sensitive display device. Users can interact with
touch screens by touching areas of the screen. You can touch words,

f. Differentiate between:
i. Data and Information
Data:
a. Facts, statistics used for reference or analysis.
b. Numbers, characters, symbols, images etc., which can be
processed by a computer.
c. Data must be interpreted, by a human or machine, to derive
meaning.
Information:
a. Knowledge derived from study, experience (by the senses), or
instruction.
b. “Information is any kind of knowledge that is exchangeable
amongst people, about things, facts, concepts, etc., in some context.
ii. Hardware is any physical device, something that you are able to touch
and software is a collection of instructions and codes installed into
the computer and cannot be touched. Hardware and software are
complementary of each other. A computer’s hardware is of no use
without software and software cannot be utilized without supporting
hardware.
iii. Input and output devices are computer hardware components. An
input device is a component used to enter data or instructions into the
computer. Keyboard, mouse, scanner, etc. are input devices. An output
device gives processed information back to the user. You can view,
print and hear the output generated by computers using different
output devices. Monitor, printer, speakers, etc. are output devices.
iv. RAM (Random Access Memory) is made up of memory chips that can
be read from and written by the CPU and other devices. RAM is volatile,
so data stored in RAM stays there only as long as your computer is
running. ROM (Read Only Memory) is a type of memory that normally
can be read only. ROM is non-volatile, so the data stored in ROM is
always there, whether the power is On or not.
v. Scanner is an input device that is used to enter images of text, drawing
and photographs and store them in the computer as electronic files.
There are three types of scanners: flatbed scanners, hand-held
scanners and drum scanners. Plotter is an output device that is used
for printing extensively in the drafting field by architects, engineers.
etc. There are two types of plotters available; flatbed and drum.
vi. A dot-matrix is an impact printer that uses hammers and a ribbon to

6
resolution of the printed image. A laser is a non impact high-speed
printer that works like a photocopier to produce high-quality images
on a page.
vii. A CD-R (compact disc-recordable) is a multi session compact disc on which you can record your own items such as text, graphics, and audio
but only for one time, and you cannot erase the disc’s contents. A
CD-RW (CD-REWRITABLE) is an erasable disc that allows you to write
multiple times.
viii. A hard disk is a storage device that is used to store data for future use.
It is mounted inside the system unit sometimes called a fixed disk. The
system unit on most desktop and notebook computers contains at
least one hard disk. A Pen drive is a small and portable storage device
popularly used these days. It is used to quickly transfer audio, video
and data files from the hard drive of one computer to another. It is
small enough to fit into a pocket.
g. The power supply unit, called SMPS (Switched-Mode Power Supply) is
the component of the system unit that converts the wall outlet AC power
into DC power. Different motherboards and computers require different
wattages on the power supply. If a power supply is not providing the
necessary power, the computer will not function properly. Built into the
power supply is a fan that keeps the power supply cool.

and embedded.
c. Linux is an operating system that is available for free on the World Wide
Web. Linux is an open source code operating system. It can be copied,
modified and redistributed.
Long-answer questions:
a. Operating System is a software that controls the overall activity of a
computer and enables all the parts to function collectively. For example,
the operating system recognizes input from an input device such as
the keyboard, mouse, microphone, or PC camera; coordinates the
display of output on the monitor; instructs a printer how and when to
print information; and manages data and instructions in memory and
information stored on disk. The operating system (OS) is the first thing
loaded onto the computer, without the operating system a computer is
useless.
8
b. Earlier the operating system was device dependent. A device-dependent
software product is one that runs only on a specific type of computer.
Now the device-independent operating system has come that can
run on computers made by various manufacturers. The advantage of
device-independent operating system is that you can retain the existing
application software and data files even if you change the model of a
computer.
c. Jobs of OS.
i. Booting a Computer: The main job of an operating system is starting
a computer. Starting or restarting the process of a computer is called
booting. Each time you boot a computer, the necessary operating
system files are loaded, or copied from the hard disk (storage) to the
computer’s memory (RAM). Finally, the Windows desktop and icons
are displayed on the screen.
ii. Managing Resources: The operating system helps in managing various
resources of the computer system. It keeps the track of all the files
and folders and also maintains a list of these files and folders into the
hard disk.
iii. Scheduling Tasks: A task is an activity or operation that a processor
performs. The operating system determines the order in which the
tasks are to be processed. These tasks include receiving data from
an input device, processing instructions, sending information to an
output device and transferring items from storage to memory and
from memory to storage.
iv. User Interface: The operating system plays an important role for
interfacing between the user and computer. The user interacts with
the computer to perform various tasks like running the application
programs, opening the document, entering the data, printing the
output reports etc. The OS makes it easy for the user to perform all
these tasks with the help of different hardware devices.
d. Types of OS
i. Single User Single Task Operating System: A single user single task
operating system is designed for one user to effectively use a computer
at a time and allows only one program to run at a time.
ii. Single User Multitasking Operating System: It is the operating system
that allows a single user to run different applications at the same
time. Microsoft Windows and Macintosh of Apple are examples of
this type.
iii. Multi User Operating System: This type of operating system allows
9
multi users to use the system simultaneously. These types of operating
systems are mostly used by the network system. UNIX and Windows
NT are examples of multi-user types of operating system.
iv. Batch Processing Operating System (BPOS): In Batch Processing
Operating System, the data and programs that need to be processed
are bundled and collected in a ‘batch’ and executed together. This
operating system is ideal in situations where a large amount of
data is to be processed or similar data needs to be processed.
In it the processing is performed automatically without any user
intervention.
v. Real-Time Operating System (RTOS): A real-time operating system
(RTOS) is an operating system that guarantees a certain capability
within a specified time period. It is specially designed to run
applications with very precise timing and a high degree of reliability. A real-time operating system offers programmers more control over
process priorities.
e. The three basic categories of operating systems are stand-alone, server,
and embedded.
i. A stand-alone operating system is a complete operating system
that works on a desktop computer, notebook computer, or mobile
computing device. Examples of currently used stand-alone operating
systems are Microsoft Windows, Mac OS, and Linux.
ii. A server operating system is an operating system that is designed
specifically to support a network. A server operating system typically
resides on a server. The client computers on the network rely on the
server(s) for resources. Examples of server operating systems include
Windows Server 2008, UNIX, Solaris, and NetWare.
iii. Embedded operating system is used on mobile devices and many
consumer electronics. It resides on a ROM chip. Popular embedded
operating systems today include Windows Embedded CE, Windows
Mobile, Palm OS, iPhone OS, BlackBerry, Google Android, embedded
Linux, and Symbian OS.

table errors and reconstructs some damaged information. It searches and
removes unnecessary files from the computer. By performing scan disk,
the performance of the computer can be increased.
11
c. By deleting all temp and unnecessary files from the PCs you will free
up space on the computer’s hard drive and increase the speed and
performance of the computer.
d. Defragmentation is a program that rearranges the files stored in a logical
order for occupying the attached storage location to increase the speed
of the computer. With time your hard disk becomes fragmented and
bloated with obsolete and invalid data that causes errors, slowdowns
and freezing of your system. To overcome this problem defragment your
computer hard disk. You should defragment the hard disk at least once a
month.
e. You can make a USB recovery drive to troubleshoot and recover from
computer problems. If a problem prevents you from booting your
computer, then you must boot with your Windows 8 installation media.
If you do not have the installation media, you can still recover if you have
created a recovery drive.
f. You can create a system image backup to protect against your system
hard drive failing or otherwise becoming unusable. If the computer
crashes you have to start from scratch with either a reformatted hard
drive or a new hard drive. This usually means that you have to reinstall
Windows 8 and then reinstall all your applications. However, if you create
a system image backup, you can restore your system quickly and easily.

changing the font and size of the data, adding colour and shading, and giving
your worksheets a more professional, polished look. Formatting makes your
19
worksheets easier to read and understand and thus more useful to others.
b. You can center a title or heading across a range of cells in your worksheet.
For example, you might want to include a title across multiple columns of
labels. You can use the Merge and Center command to quickly create a
merged cell to hold the title text.
c. You can use number formatting to control the look of numerical data in
such a way, like if you have a data of some prices, the currency formatting
can be applied to that data. Excel provides such 12 number formats to
choose from.
d. You can use Excel’s Theme Gallery to apply a combination of formatting
settings (colours, fonts, and effects) that give your spreadsheet a professional
and cohesive appearance. You can choose from 20 built-in themes.
e. You can add borders to your worksheet cells to help define the contents or
more clearly separate the data from surrounding cells.
f. LivePreview feature enables you to see how a new font, font size, table
style, cell style, or number format would look on your selected data before
you actually apply it. You can use Live Preview by placing your mouse
over the thumbnails to see how each of its styles will look on your actual
data. When you see the formatting that fits your data to a tee, just click its
thumbnail to immediately apply it to the selected cell range.

b. +, -, *, /, %, ^
e. SUM, MAX, MIN, AVG
f. Math & Trig, Statistical, Date & Time, Financial, etc.
Long-answer questions:
a. In Microsoft Excel, you can perform mathematical calculations, such as
addition, subtraction, multiplication, and division using formulas.
b. Formulas are equations that perform calculations on values in your
worksheet. A formula starts with an equal sign (=). An Excel formulas have
a general structure, an equal sign (=) followed by one or more operands
which can be values, cell references, ranges, range name or function
names.
c. Arithmetic formulas are the most common type of formulas. These
formulas combine number, cell reference, and function result with
mathematical operators to perform calculations.
A comparison formula is a statement that compares two or more numbers,
text, cell contents or function result.
The reference formulas combine two cell ranges to create a single joint
reference.
d. Operators are symbols that specify the types of calculations to be
performed. Arithmetic operators are addition (+), Subtraction (-),
Multiplication (*), Division (/), Percentage (%), Exponentiation (^).
Comparison operators are Equal to (=), Greater than (>), Less than (<),
Greater than equal to (>=), Less than equal to (<=), Not equal to (<>).
Reference operators are Colon (:), Space, Comma(,).
e. Cell reference is a unique address of each cell. By default, cells are
identified by a specific column letter and row number, so cell A5 identifies
the fifth cell down in column A. When entering formulas, use cell
references instead of actual data whenever possible. Range is a group of
related cells in a worksheet. The range cells are separated by a colon (:).
For example, the range name A1:B3 includes cells A1, A2, A3, B1, B2, and
B3. Range names must start with a letter. You cannot add space in range
names.
f. Functions are the pre-written inbuilt formulas that can be used for making
useful calculations quickly and easily. Functions differ from regular
formulas in which the values are supplied but not the operators, such as
+, -, × or /. Excel provides over 300 functions that can be used to perform
calculations. SUM, AUTOSUM, AVERAGE, COUNT MAX are some of the
commonly used functions.
g. Different types of function
i. Cube: You can use cube functions take the OLAP data and display it in
21
a cell if you are using complex OLAP formulas (such as Pivot Tables).
ii. Date & Time: You can use these functions for calculating dates, times,
and minutes.
iii. Engineering: You can use this function for engineering calculations.
iv. Financial: You can use this function for calculating and tracking loans,
principal, interest, yield, depreciation, and future values.
v. Information: You can use this function for testing your data.
vi. Logical: You can use this function for logical conjectures, such as ifthen statements.

e. IF-THEN-ELSE
Long-answer questions:
a. BASIC stands for Beginners All Purpose Symbolic Instruction Code. It is
one of the programming languages developed by Prof. John G. Kemeny
and Thomas E. Kurtz in 1964. There are different versions of BASIC such
as GW- BASIC, Turbo BASIC, QBASIC, Visual BASIC, etc. In this chapter you
are going to learn about QBASIC or Quick BASIC.
b. Program Mode: In program mode the complete program is typed and the
F5 key is pressed to execute or run the program to get results.
Immediate Mode: In immediate mode simple statements are typed which
get executed immediately after pressing the enter key at the end of the
statement.
c. Every programming language has some special set of commands to give
22
instructions to the computer. So QBASIC also has different commands
which are used to write programs.
d. Describe the following with syntax:
i. REM statement is used to write comments in the program. REM
statement is a non executable statement. They are used only to add
explanatory notes in the program. Syntax: REM Comment
ii. LET statement is used to assign a value or data to the variable. The
value of a LET statement cannot be changed at the time of execution.
Syntax: LET < variable name > = value
iii. The INPUT statement is used to assign the value or data to variables
at the time of execution. For example, when a user runs the program,
a question mark (?) appears on the screen to get the value of a
variable. Syntax: INPUT “Message”; <variable>
iv. The PRINT statement is used to display the output on the screen.
Text messages can also be printed by using PRINT statement. Always
remember that the messages given in a print statement must be
closed in quotes (“ ”). Syntax: Print “Message” a variable or Constant.
v. CLS command is used to clear the screen. This command removes the
output of the previous program from the screen and makes it blank.
Syntax: CLS
vi. The GoTo statement enables you to jump to certain positions within
the program. Labels are used to specify what point in the program to
execute. Syntax: Go To <label>
vii. IF-THEN-ELSE statement is a conditional control statement in which
“IF” is a logical or arithmetic expression, “THEN” is an instruction and
“ELSE” is another instruction or label. Syntax: IF (condition) THEN
(action 1) ELSE (action 2)

Long-answer questions:
a. E-mail is an electronic mail, the most frequently used application of the
Internet. It has become a powerful tool of communication because it is an
economical, convenient and fast way of sending and receiving messages.
All types of messages from simple text to pictures, sound and video files
can be sent through it. The message sent through e-mail can be reached
within a few minutes.
b. E- mail is one of many technological developments that has influenced
our lives.
i. Easy to use: E-mail frees us from the tedious task of managing data of
daily use. It helps us to manage contacts, send mail quickly, maintain
mail history, etc.
ii. Speed: E-mail is delivered instantly, any where across the globe. No
other service matches e-mail in terms of speed.
iii. Reliable & Secure: E-mail is one of the most secure ways of
communication and constant efforts are also being taken to improve
the security in electronic mails.
iv. Environment Friendly: Postal mails use paper as a medium to send
letters. E-mail thus, saves a lot of trees from being axed. It also saves
fuel needed in transportation.
v. Advertising tool: E-mail is also used to advertise the products of many
individual companies.
c. An E- mail address is a unique address for each user. It is a system for
sending and receiving messages through e-mails over a computer
network. An E-mail address consist of two parts, a user name and a
domain (or host) name with an @ symbol (at) for separating them. You
can get an E-mail address by creating your own e-mail account. Creating
an E-mail just involves filling an online form with your details. Once you
have filled in everything correctly and agreed to the terms and conditions
of the service, your e-mail account will be ready to use.
d. To send an e-mail, you need an Internet connection and access to a
mail server that forwards your mail to its final destination. The standard
protocol used for sending Internet e-mail is called SMTP (Simple Mail
26
Transfer Protocol). It works in conjunction with POP (Post Office Protocol)
servers. When you send an e-mail message, your computer routes it to an
SMTP server. The server looks at the e-mail address and forwards it to the
recipient’s mail server, where it get stored until the address retrieves it.
e. Different components of e-mail
i. Sender (From): This contains the sender’s e-mail address.
ii. Recipient (To): It contains the e-mail address of the recipient, or where
the message is supposed to be sent.
iii. Carbon Copy (CC): You can sent the message to a person who is not
directly involved, but you would like the message to be known to him,
his e-mail address is written in this section.
iv. Blind Carbon Copy (BCC): You can use BCC if you want to send the
same message to several people, without letting then know that
others have also received the same message.
v. Subject: Subject is a description of the topic of the message.
vi. Send: This button is used to send the e-mail message to the
recipient.
f. E-mail viruses are spread by files attached to e-mail messages. As e-mail
attachments become more common, the number of e-mail viruses may
also increase. If a stranger sends you a message that has an attachment,
do not open the attachment. Here the term ‘stranger’ is used for a person,
company, or organization that you do not know and that you have never
had any dealings with in the past. If you receive a message with a file
attachment that you suspect is a virus, delete the message immediately.
g. A phishing message is a junk e-mail message that appears to come from
a legitimate organization such as a bank, a major retailer. The message
will ask you to update your information or warn you that your account is
about to expire. When you enter the required data—such as your credit
card data, your social security number, or your online banking password—
that data is sent to the scammer.

b. An E-mail address is a unique address for each user. An E-mail address
consists of two parts, a user name and a domain (or host) name with a
@ symbol (at) for separating them.
Your user name is a unique combination of characters that identifies you.
Domain name is separated into two parts by the period (.), and it is the
location of the person’s account on the Internet. It specifies which server
the e-mail should be delivered to, e.g., the address minhasds@gmail.com
means the user name “xyz” at the domain “gmail.com”.
c. Junk e-mail—also called spam—refers to unsolicited, commercial e-mail
messages that advertise a wide variety of products.
Precautions for Junk e-mail
Most people receive at least a few spams a day and some even receive
hundreds of them. No matter how many you receive, first ensure a
message is junk and then delete that message. Never open suspected
spam messages. Doing so can sometimes notify the spammer that you
have opened the message. This proves to the spammer that the
message was delivered to you successfully and your address is
legitimate, and so you will likely receive even more spam.
d. Formatting features is a very useful feature in MS Excel. It is used to create
an interesting effect that you may find useful. The formatting provides
an attractive and interesting look to the worksheet.
The formatting features like changing the font, size of data, adding colour
and shading makes your worksheet more presentable.
e. MS Excel has grouped functions in eleven categories and each category
has a variety of functions:
i. Date and Time– These functions are used for calculating dates and
29
times.
ii. Financial– This function is used for calculating and tracking loans,
principal, interest, yield, depreciation, and future values.
iii. Text– This function is used to search and replace data and other text
tasks.
f. Commands are a special set of instructions/order given to the computer
to perform a specific task. For example,
INPUT “enter the number”; N
INPUT “What is your name?”; N$
