2.Star topology and Bus topology
In Star topology, all the workstations are connected to a central connection point called
a hub. Any data that is sent to the other computer, first goes to the central hub and from
there it is redirected to the destination computer whereas Bus topology is made up of
a main single cable with the terminators at both ends. It is the shared communication
medium that makes the backbone of the system. Computers and the other devices
including the server are connected to this linear cable for communication.

5.Client/Server and Peer-to-peer Architecture
Client/Server Architecture
Client/Server architecture is defined as a
specific type of a network which consists
of a single powerful computer acting as
a server usually connected to multiple
computers called clients.
Peer-to-peer Architecture
Peer-to-peer architecture is a type of
network in which each workstation has
equivalent capabilities and responsibilities.
The workstations are connected to each
other but do not have a server. Files can
be shared between workstations, and a
printer connected to one workstation can be
accessed by other workstations as well.
It runs the risk of a system overload.
It supports distributed processing, so the
increased load does not affect the system
overall.

E. 1.A network consists of two or more computers linked together for sharing resources such as
printers and exchanging files, or allowing electronic communications. The computers on a
network may be linked through cables, telephone lines, radio waves, satellites, or infrared
light beams.
Advantages: Advantages of networking include centralised software management,
resource sharing, increased speed and security and cost efficiency.
Disadvantages: Some disadvantages of networking are given below.
a.As traffic increases on a network the performance degrades unless it is designed
properly.
b.It becomes difficult to manage when a large number of computers is connected to a
network.
c.In case the server is hacked or attacked by a virus, the security of data of all connected
computers is at risk.
2.The different components of a computer network are given below.
a.Server: A server is a computer that manages the network resources, software and files. It
is normally dedicated to an allocated task and it performs no other task.
b.Workstation: A workstation is a computer intended for individual use in a networking
environment. It is like a personal computer except that it is also connected to other
computers along with the main computer, that is, the server.
c.Network Interface Card: A network interface card (NIC) is a piece of hardware placed
inside the system unit. It is part of the motherboard. It is designed to allow computers
to communicate over a computer network. It provides physical access to a networking
medium.
d.Hub: A hub is a device that connects multiple devices and makes them work as a single
network segment. A hub has multiple ports. A specific cable connects the hub to the
NIC. The NIC transfers the data on a computer to a hub, which then transfers it to the
other connected computers.

e.Transmission channels: Each computer on a network is interconnected through
transmission channels. These channels can be wired or wireless. Data is exchanged
between two computers on a network using these channels.
3.The physical arrangement of cables, computers and other peripheral devices to form a
network is known as a topology. Different types of topologies used in computer networks
are discussed below.
a.Bus topology is made up of a main single cable with the terminators at both ends. It is
the shared communication medium that makes the backbone of the system.
b.Star topology is the most common topology used. Here all the workstations are connected
to a central connection point called a hub. Any data that is sent to the other computer, first
goes to the central hub and from there it is redirected to the destination computer
c.In a ring topology, every workstation has exactly two neighbours for communication
purposes. All messages travel through a ring in the same direction either clockwise or
anticlockwise.
4.To manage all the important features in phones, a special type of operating system called
mobile operating system (or mobile OS) is required. This operating system is used in
smartphones, tablets and other mobile devices.
Android by Google, iOS by Apple, Windows phone by Microsoft, BlackBerry by RIM are
some examples of mobile OS.
5.Reasons for developing a mobile app are given below.
a.A mobile phone is a compact machine with small battery size so the OS should be
designed in a simple way to work with limited power for a longer period of time.
b.Limited memory is available in mobile phones therefore OS should be less complex to
occupy less storage capacity.
c.Mobile phones are equipped with in-built keyboard so a different Graphical User
Interface (GUI) is required.

In this reference, when the formula or
function is copied and pasted to other
cells, the cell references in the formula or
function change relative to the location
where it is copied.
2.Filter and Advanced Filter
In this reference, if the formula is copied
across rows or down columns, the formula
value does not change.
Filter
When you apply Filter to a worksheet, grey
colour drop-down controls (Filter switches)
appear to the right of the column headings
of a list. Using these switches, you can filter
any data.
3.Ascending and Descending Orders
Advanced Filter
When you apply Advanced Filters to a
worksheet, it helps to filter list based on a
specific criteria or to copy the filtered data
to a different location.
Ascending Order
Arranging the data in an increasing order.
For example, letters from A to Z and
numbers from lowest to highest.
4.Auto Filter and Custom Filter
Descending Order
Arranging the data in a decreasing order.
For example, letters from Z to A and
numbers from highest to lowest.
Auto Filter
Auto-filters provide users an interactive way
to put constraints on how data is displayed.
The criteria can be selected from some
predefined conditions.

D. 1.Cell reference identifies the location of a cell or group of cells in the spreadsheet. Cell
reference is also known as cell address. A cell reference consists of the column letter and
row number that intersect to form a cell.
a. Relative reference: A relative cell reference in a formula is based on the relative
position of the cell contained in the formula. By default, a spreadsheet cell reference
is relative. For example, if a formula =A1+B1 or SUM(A1:B1) is written in cell D1 and is
copied to E1, then the formula will change to =B1+C1 for cell E1.
b. Absolute reference: Absolute cell reference in a formula always refers to a cell in a
specific location. This is done by fixing the cell by using dollar sign ($) in front of a row
and a column. For example, if a formula =$A$1+$B$1 is written in cell D1 and is then
copied to E1, the formula will remain as it is for D1, that is, =$A$1+$B$1.
c. Mixed reference: A mixed reference has an absolute column and a relative row, or an
absolute row and a relative column. An absolute column reference takes the form $A1,
B$1, and so on. For example, if you copy a mixed reference formula =A$1+B$1 from
6

20/04/21 8:03 PM
cell D1 to cell E1, the formula changes to = B$1+C$1. In this case, the row is fixed. It will
not change even if the location changes in the worksheet.
2.Data when entered in a sheet may not be arranged in an order. However, you can arrange it
in either ascending or descending order. This physical rearrangement of data in ascending
or descending order is called sorting. There are two types of sorting: Ascending order and
Descending order.
3.A chart is a graphical representation of information. A chart often makes it easier to
understand the data in a worksheet because users can easily pick up patterns and trends
illustrated in the chart that are otherwise difficult to see.
4.Charts are a great tool to analyse and depict data graphically. Different types are charts
are used for different purpose. For example, bar charts are for comparing concepts and
percentages among factors or sets of data. Pie charts are good for illustrating and showing
sample break down in an individual dimension.
5.Follow these steps to import data into an Excel 2010 sheet:
a.Select Data tab. Click on From Text option in the Get External Data group. Import Text
File dialog box appears.
b.Select the file from its destination folder or type in the name of the file in the File name:
box. Click on the Import button.
c.The Text Import Wizard dialog box appears. Click on the File origin: drop-down list and
select Windows (ANSI). Click on Next > button.
d.Mark the desired options in the Delimiters section. Click on Next > button. A preview of
the chart based on the options chosen can be seen in the Data preview section.
e.Select the appropriate column data format in the Column data format section. Click on Finish.

B. 1. Assembler and Compiler
An assembler is a utility software program which is used to convert a program written in
assembly language into machine language and vice-versa whereas a compiler is a utility
software program that transforms the source code written in high-level language into
machine language (object code) that a computer can understand.
2.Compiler and Interpreter
The compiler converts the entire source code into object code in one attempt and
generates the error-list with line numbers (if any). Once all the errors are rectified, the code
gets transformed into object code. Whereas an interpreter is a utility software program that
translates the source code into intermediate code and immediately executes it line-by-line.
The object code is not stored in a separate file.
3.Source code and Object code
Source code is the input to the compiler of the language in which it is written whereas the
Object code is the machine executable file having instructions for the machine in the form
of binary digits, generated by the compiler.

4.Procedural programming and Object Oriented Programming
Procedural programming refers to functions and the execution of the functions in a
step-by-step linear order. It emphasises more on procedure than data whereas in Object
Oriented Programming, a program is no longer a series of instructions, but a collection of
objects. These objects contain both data and instructions that are assigned to classes and
can perform specific tasks.

D. 1. A program is a set of instructions written and executed in a specific sequence.
2.The five generations of computer languages are given below.
a. First generation: Machine Language
b. Second generation: Assembly language
c. Third generation: High level language d. Fourth generation: Very high level language
e. Fifth generation: Artificial intelligence
3. Important points are:
a. First generation computer language is the lowest level of computer language.
b.Information was entered into the computer in the form of long series of 1s or 0s or the
binary codes. These codes can easily be interpreted by a computer.
4.The important features of fourth generation computer language are:
a. Instructions are written in English-like sentences.
b. These are non-procedural.
c.Increases productivity because programmers type fewer lines of code to get something
done.
5.In Object Oriented Programming approach, programmers can build programs from
pre-existing objects and can use features from one program in another. These results in
faster development and thus it saves time, reduces maintenance costs, and improves
flexibility for future revisions.

D. 1. There are four types of loops available in QB64. These are:
a.The FOR ... NEXT structure is used when you want to perform a loop a specific number
of times. It uses a counter variable which is incremented or decremented with each
repetition of the loop.
b.A DO WHILE ... LOOP is performed and then the condition being tested is checked, the
next loop cycle goes if condition is true.
c.DO UNTIL … LOOP is very similar to the DO WHILE ... LOOP. The only difference is that
the DO UNTIL ... LOOP is executed ‘until’ a certain condition is reached rather than ‘while’
a certain condition is met.
d.WHILE … WEND works just like any other loop. It executes a series of statements as long
as a specified condition is true.
2.FOR ... NEXT structure is used when you want to perform a loop for a specific number of
times. It uses a counter variable which is incremented or decremented with each repetition
of the loop.
Syntax
FOR counter_variable = StartValue TO EndValue STEP StepValue
Statement1;
Statement2;
NEXT counter_variable
3.DO UNTIL … LOOP is different from DO WHILE ... LOOP as it executes the statements until
the condition is true. In other words, it executes the statement if the condition is false and it
exits the loop if the condition is true.
4. WHILE test condition
Statements

D. 1.QB64 is not a graphic-oriented programming language. It was meant to be a learner’s
language for basic programming techniques. However, with the help of some of its
functions, we can achieve some level of graphic quality.
2.The SCREEN command is used to set the screen attributes. The screen attributes are always
in number.
Syntax of SCREEN command is given below.
SCREEN [mode]
where mode is any number from 1 to 13 for graphics and 0 for Text.
3.It is used to change the colour of the screen and the text. 16 colours can be used in QB64.
4.A pixel is the smallest possible element of an image on the screen.
5.The computer screen that you see consists of hundreds of picture elements known as
pixels. Resolution of the screen or the image displayed is measured in terms of the pixels
present horizontally and vertically on a screen.
For example, resolution 320 × 200 for an image would mean 320 pixels in horizontal
direction and 200 pixels in vertical direction.

<Body> tag is used to specify the body of a webpage like its background image colour and
the specification of text/content in body while <P> is the paragraph tag. It is used to specify
formatting and content related to a specific paragraph.
3.<I> and <B>
<I> stands for Italics tag, a tag used for displaying text in italics while <B> stands for Bold
tag, a tag used for displaying the text in bold.
4.<SUP> and <SUB>
<SUP> stands for superscript, used to write text slightly above the normal level. For
example, A² will produce A2. While <SUP> stands for subscript, used to
display the text in the subscript format. For example, H<SUB>2</SUB>O will produce H2O.
5.<BR> and <NOBR>
The <BR> tag is an empty element. It is used to give a forced line break without inserting
any blank space in between the lines whereas the <NOBR> tag is a container element that
prevents line break.

3.Date of birth: 12th August 1988
E. 1. HTML is a simple scripting language, mainly used for developing web pages.
The content typed along with the start tag and the end tag is called the HTML element. For
example, <B> Click Start </B> is one HTML element. HTML can also have nested elements.
For example, <B> <U> Click Start </U> </B>.
2.Attributes of a tag provides additional information about the HTML elements. They are
always written by giving a space after the tag name. Attributes appear as an attribute name
followed by an ‘=’ sign and then the attribute value. Attribute values should be enclosed
within double quotes, though some browsers allow single quotes as well.
3.Type the program using ant text editor (say Notepad). Save the file with the extension .HTM
or .html. Open the file using any browser say Internet Explorer to execute the script.
4.Hyperlinks are the text/images which link a word or a picture to some additional
information in the same page or on some external page. For example, <A href=“http://
www.cambridgeindia.org”> SEARCH FOR NEW BOOKS PUBLISHED</A> will display a
hyperlink on the web page.
5.Tags which are used to give formatting effects to the text in a web page are called the
formatting tags. Some of these tags are explained here.
a. Bold Tag: This tag helps to display the text in bold. It is a container element. The text
written between the <B> and </B> tags appear darker than the rest of the text. This
tag is generally used to give headings or to highlight important terms.

different tags to create different types of lists. Some of the different types of lists are
discussed here.
a. Unordered list: An unordered list is a list of items where the sequence of the list is not
significant. By default, it is marked with bullets.
