Q. 2 What are the limitations of portable computers? Do you think students should
be allowed to use computer in class? (5m)
The computers that are designed to be placed from one place to another and
includes a display and keyboard, are called portable computers. By their nature,
portable computers are generally known as microcomputers. Portable computing
started in 1981, when Adam Osborne introduced his CP/M-based business computer
called the Osborne I.
Limitations of a portable computer:
They have a lower specification than most desktop systems.
They are less user- friendly and are less suited for full-time usage in most of the
cases.
Expansion is tough and any repair could prove costly.
Most of portable computers are not upgradeable.
The computers are becoming more popular for home use and outside works.
Modern-day technologies have changed the dynamics of our lives. It depends on the
user as to how they can make the use of technology.
.
Q.3 What is an operating system? What are it's major functions? (5m)
An operating system is a software that works as an interface between a
user and the computer hardware. The primary objective of an operating
system is to make computer system convenient to use and to utilize
computer hardware in an efficient manner. The major functions of OS are
cited below:

also provide proper authentication and authorization to computer system
and its resources for security and protection.
Q. 4. How operating system is transferred to internal memory? (5m)
Operating System is a piece of software that controls all our computer
resources while the computer is in use. Often people have questions like
where the operating system is stored on the computer or how it is being
used by CPU? Someone says it is stored in RAM while other says it is on the
hard disk.
RAM (Random Access Memory) is the volatile memory space that stores
the data which is directly accessed by CPU (Central Processing Unit). The
data/software access from the RAM is much faster than the access from
the hard disk, so computer’s speed directly depends on the RAM as if there
is higher memory space in the RAM, it will reduce the time to read data
from hard disk. But since it is volatile, as soon as computer is turned off,
the data stored in the RAM.
Conclusion:
In computers, Operating System is installed and stored on the hard disk.
As hard disk is a non volatile memory, OS does not lose on the turn off. But
as the data access from the hard disk is very, slow just after the computer
is started OS is copied into RAM from the hard disk.

Unit: 6 (Computer Networks/Network Configuration)
Q.11 Write a summary of the text "Computer Network"
The text entitled " Computer Network " presents important information about
various types of computer networks and their uses as well. Computer networks link
computers by communication lines and software protocols, allowing data to be
exchanged rapidly and reliably.There are three types of computer networks described
in the text are explained below:
1. LAN ( Local Area Network)
Local Area Network is a group of computers connected to each other in a
small area such as building, office.
LAN is used for connecting two or more personal computers through a
communication medium such as twisted pair, coaxial cable, etc.
It is less costly as it is built with inexpensive hardware such as hubs, network
adapters, and ethernet cables.
The data is transferred at an extremely faster rate in Local Area Network.
In the 1980s, at least 100,000 LANS were set up in laboratories and offices
around the world. During the early part of this decade, synchronous orbit
satellites lowered the price of long-distance telephone calls, enabling
computer data and television signals to be distributed more cheaply around
the world. Since then, fibre-optic cable has been installed on a large scale,
enabling vast amounts of data to be transmitted at a very high speed using
light signals.
2. WAN (Wide Area Network)
A Wide Area Network is a network that extends over a large geographical
area such as states or countries.
A Wide Area Network is quite bigger network than the LAN.
A Wide Area Network is not limited to a single location, but it spans over a
large geographical area through a telephone line, fibre optic cable or
satellite links.
The internet is one of the biggest WAN in the world.
A Wide Area Network is widely used in the field of Business, government,
and education.
3. Distributed Network System
Distributed networking, used in distributed computing, is the network system
over which computer programming, software, and its data are spread out
across more than one computer.
Distributed networks and processing work together to deliver specialized
applications to different remote users. This means that an application may be
hosted and executed from single machine but accessed by many others.

Subject: Purchase of Five Photocopiers.
Dear Sir,
It is informed that our college was using Epson Photocopiers which are no longer adequate to meet
all our needs. They are about 15 years old and they lack versatility. Moreover, they get interrupted
frequently and need major repairs. This year alone we had to spend Rs. 20,000 to keep them in
working order.
With the increment in the size of four teaching departments and consequent increase in the
number of both faculty and students, the load of work has gone up considerably. Our estimates
show that we now require at least five more photocopiers to meet the present day demands.In
addition, we have also studied the feature of various types of photocopiers currently available in the
market. We recommend the purchase of Epson, each costing Rs. 1,60,000/- manufactured from
Delta Private Ltd., Koteshwar, Kathmandu.
I request you to accord your kind approval for the purchase of photocopiers.

Unit: 4 (Programming and Programming Languages)
Q.8 Write a summary of the text ' Programming and Programming
Languages'. (10m)
A programming language is a set of commands, instructions, and other
syntax use to create a software program.In other words, A programming
language is a computer language programmers use to develop software
programs, scripts, or other sets of instructions for computers to
execute.Some major programming languages have been described below:
FORTRAN acronym for FORmula TRANslation. This language is used for
solving scientific and mathematical problems. It consists of algebraic
formulae and English phrases. It was first introduced in the United States in
1954.
COBOL acronym for COmmon Business-Oriented Language. This language
is used for commercial purposes. COBOL, which is written using English
statements, deals with problems that do not involve a lot of mathematical
calculations. It was first introduced in 1959.
ALGOL acronym for ALGOrithmic Language. Originally called IAL, which
means International Algebraic Language. It is used for mathematical and
scientific purposes. ALGOL was first introduced in Europe in 1960.
BASIC acronym for Beginner's All-purpose Symbolic Instruction Code.
Developed in 1965 at Dartmouth College in the United States for use by
students who require a simple language to begin programming.
C Programming language is used for developing firmware or portable
applications. Originally intended for writing system software, C was
developed at Bell Labs by Dennis Ritchie for the Unix Operating System in
the early 1970s.The program produced after the source program is
converted into machine code is referred to as an object program or object
module. This is done by a computer program called the compiler. For
example, in order that an IBM RS/6000 may process a program in
FORTRAN, it needs to have a compiler that would understand that
particular model and the FORTRAN language as well.The compiler is a
system program which may be written in any language, but the computer's
operating system is a true systems program which controls the central
processing unit (CPU), the input, the output, and the secondary memory
devices.
Conclusion:
The main purpose of programming languages is to provide instructions to
a computer. As such, programming languages differ from most other forms
of human expression. Many new programming languages are being
created as per the needs of computer users like C++, javascript and python,
etc.

Unit: 5 (Computer Software)
Q.9 Mary Evans, Gerry Harper, Matt Andrews and Bob Bolton are well
known software developers. Do you think software purchasers are
getting what they need? What are their views about giving a better
product to purchase? (10 m)
In the text entitled 'Computer Software', the four software developers
have presented their own views about the computer software.
Mary Evans thinks that people are getting what they want- there are a lot
of creative things being done with paint software, word processing. DTP
(desktop publishing) systems, and so on.The computer is an incredibly
powerful tool, and any software that makes it easier, faster, more creative,
or more cost-effective will inevitably be in demand. But she is generally
optimistic about the way things are going at the moment.She thinks most
of the major software manufacturers are able to read the market quite
well.
According to Gerry Harper, software purchasers are getting the technical
support they need. While the products are getting more and more
complex, and more and more expensive, it seems that support is starting
to be thought of as an additional business opportunity.He thinks that
applications are getting too big, and that they're trying to do too much.
Yes, they're versatile and powerful, but they're also often .He wants simple
little programs that are easy to understand and use, and that work
together to accomplish more complex tasks.'
Matt Andrews doesn't agree with them.He tells that we can't stop
progress. Suppliers know what their customers want - they just can't
supply it quickly enough. He has studied the market very closely, and has
found that purchasers' needs seem always to exceed the capability of the
available software by a constant time-frame of about six to twelve
months."
Bob Bolton thinks that users are getting what they want. provided that
their needs fit the off-the-shelf application. Specialized software is usually
so specific that it should be written in-house for businesses. Developers
should add features that the customer needs, not what they think
customers want. Some effort should be made to get s feedback from the
users before making an upgrade so that the proper features are added.

Unit:6 ( Computer Networks)
Q.10 Write a summary of the text "Computer Network"
The text entitled " Computer Network " presents imortant information about
various types of computer networks and their uses as well. Computer networks link
computers by communication lines and software protocols, allowing data to be
exchanged rapidly and reliably.There are three types of computer networks described
in the text are explained below:
1. LAN ( Local Area Network):
Local Area Network is a group of computers connected to each other in a small
area such as building, office.
LAN is used for connecting two or more personal computers through a
communication medium such as twisted pair, coaxial cable, etc.
It is less costly as it is built with inexpensive hardware such as hubs, network
adapters, and ethernet cables.
The data is transferred at an extremely faster rate in Local Area Network.
In the 1980s, at least 100,000 LANS were set up in laboratories and offices around the
world. During the early part of this decade, synchronous orbit satellites lowered the
price of long-distance telephone calls, enabling computer data and television signals
to be distributed more cheaply around the world. Since then, fibre-optic cable has
been installed on a large scale, enabling vast amounts of data to be transmitted at a
very high speed using light signals.
2 . WAN (Wide Area Network)
A Wide Area Network is a network that extends over a large geographical area such
as states or countries.A Wide Area Network is quite bigger network than the LAN.
a) A Wide Area Network is not limited to a single location, but it spans over a
large geographical area through a telephone line, fibre optic cable or satellite
links.
b) The internet is one of the biggest WAN in the world.A Wide Area Network is
widely used in the field of Business, government, and education.
3. Distributed Network System
a. Distributed networking, used in distributed computing, is the network system
over which computer programming, software, and its data are spread out
across more than one computer.
b. Distributed networks and processing work together to deliver specialized
applications to different remote users. This means that an application may be
hosted and executed from single machine but accessed by many others.
Q.11 Write a summary of the text "Computer Viruses.” (10m)
The text entitled,"Computer Viruses" presents the important information
about the computer viruses and its functions and more.
The computer virus - an unwanted program that has entered your system
without you knowing about it. It has two parts- the infector and the
detonator. They have two very different jobs. One of the features of a
computer virus that separates it from other kinds of computer program is
that it replicates itself, so that it can spread (via floppies transported from
computer to computer, or networks) to other computers. After the
infector has copied the virus elsewhere, the detonator performs the virus's
main work. Generally, that work is either damaging data on your disks,
altering what you see on your computer display, or doing something else
that interferes with the normal use of your computer.
Here's an example of a simple virus, the Lehigh virus. The infector portion
of Lehigh replicates by attaching a copy of itself to COMMAND.COM (an
important part of DOS), enlarging it by about 1000 bytes. Once it has
infected four copies of COMMAND.COM, the detonator is activated. The
detonator in Lehigh is a simple one. It erases a vital part of the hard disk,
making the files on that part of the disk no longer accessible. Many viruses
have spread through pirated - illegally copied or broken - games. This is
easy to avoid. Pay for your games, fair and square. If you use a shared PC
or a PC that has public access, such as one in a college PC lab or a library,
be very careful about putting floppies into that PC's drives without a writeprotect
tab.
Conclusion:
To protect computer from the viruses, the little common sense and the
occasional virus are essential.The users should also stay away from pirated
software and putting floppies in publicly available PCs.

of things human beings can do over the internet is extremely great.It has
changed the lifestyle of all human beings in all fields.
Q.13 What do you understand by network configuration? Discuss its
types. (10m)
A network configuration (topology) is the process of arranging the
devices like computers for transmitting voice, audio, data, files and other
items of information. Both the software and hardware are systematically
placed with other essential requirements.
There are four types of network configuration.They are discussed as
follows:
Ring Network Configuration:
It is a network configuration where device connections create a circular
data path.
Each networked device is connected to two others, like points on a
circle.
In a ring network, packets of data travel from one device to the next
until they reach their destination. Most ring topologies allow packets to
travel only in one direction.
Star Network Configuration:
Star topology is a network setup for a Local Area Network (LAN) in which
all nodes are individually connected to a central connection point, like a
hub or a switch.
The main advantages of a star network is that one malfunctioning node
does not affect the rest of the network.
Bus Network Configuration:
Bus topology is a network type in which every computer and network
device is connected to a single cable.
It transmits the data from one end to another in a single direction.
Switched Network Configuration:
It is a kind of network setup in which a telephone exchange works as a
central switch.
It is used to connect multiple devices on the network directly.The two
devices can communicate without the interference from other devices
when the link is established.
Conclusion:
Computer Network Topology has many advantages and
disadvantages.Each system has its own features.The use of it depends
upon the area where it is used.
Q.14 What are the positive aspects and negative aspects of replacing
humans with computers? (10m)
The computer is an electronic device that takes input from the user and processes
these data under the control of a set of instructions and gives the results as needed.
Nowadays, computers have become the most powerful tool almost in every
fields.Most of the organizations today require the use of computers.They have not
only advantages, but aslo have many disadvantages.The advantages are as follows:
The computers are used for recording data in the offices.
1. Bank is using computers for maintaining accounts and managing financial
transactions.
2. They are providing facilities of online banking; customer can check their account
balance from using the internet.
3. They are used for distance/ online education.
4. They are faster and cost- effective tool.
The negative aspects or the disadvantages of replacing people with computers in the
office are as follows:
a) It may enable people for cyber crimes.
b) It encourages and facilitates for data piracy. It has bad impact on job market.
c) It may increase unemployment.
d) There can be the chances of data stolen and hacking that destroy data.
e) It makes the students non- creative.
f) It façilitates computer crime and cyber theft. So, we must be aware on the
negative aspects of computer.
Conclusion:
Although computers have several disadvantages but the advantages of the
computer simply overcome them. Nowadays, computers can be seen in almost every
sector making the jobs easier for human beings
Q.15 Write an essay on " The computer in education" in 200 words.
(10m)
Computer has played very positive as well as negative roles in the field of
education. In this 21st century, the computers have been hugely used in
schools and colleges. Computers have given a lot of benefits both for the
teachers and students. Teachers can get reference materials easily, and
students can refer to readings and reference materials in a click.
Computer technology has had a deep impact on education sector. The
advantages of computers in education primarily include:
1. Attendance and record keeping
2. Quick data processing
3. Audio-visual aids in teaching
4. Storage of Information
5. Better presentation of information
6. Access to the textbook through Internet
7. Quick communication between students teachers and parents
8. Saving time and cost
9. Online education
10 Easy for preparing research, project, and assignment
11. Dictionary and educational software can be used as learning tools.
Although computer has played a key role in the modern education system,
many people argue that over dependence on technology can make the
students less creative and passive. It is said that computers affect students'
creativity and stop them to think innovatively. In computers, there are so
many games which make the students addictive to play. Sometimes,
students simply download materials from the Internet directly without
understanding them. There are also many things in the Internet that spoil
the youngsters‟ mind and make them deviated from studies. As computers
are becoming an important tool for teaching, teachers should be aware of
their roles in education.
Conclusion:
There are both the advantages and disadvantages of using computer in
education. If the quality and quantity of computer education are rightly
balanced, it is sure that the negative consequences can be minimized and
positive impacts can be maximized.
Q.16 Write an essay on 'Computers in Medicine' (10 m)
Over the last few years, the medical field has become increasingly reliant
on computers to bring the most advanced forms of diagnosis and
treatment to patients. The application of the computer in health care has
helped doctors and researchers advance medical science while expanding
the level of care for patients.
Medical Imaging software: Medical imaging is a technology used to create
images of the human body for study and diagnosis. It includes magnetic
resonance imaging (MRI), ultrasound, CT scans and X-Rays. All of these
devices are controlled by computers.
Patient Monitoring software: Modern computer-based patient monitoring
machines allow heart rate, respiratory activity, blood pressure and other
critical vital signs to be collected automatically in digital form.
Computer-Assisted Surgery: Computers are used to assist in planning,
teaching and performing many surgical procedures. One of the biggest
recent developments in this area is robotically-assisted surgery (RAS).This
allows surgeons to use robotic devices and computer software to complete
difficult operations.
Medical Databases application: Computers have brought the development
of many useful software solutions in the medical field. Large public health
organizations like the World Health Organization and the Centers for
Disease Control have huge databases of information related to diseases
and health statistics.
Electronic Health Record (EHR): It is the most common type of software
used in most healthcare units. Electronic health record software stocks
patient’s information, such as medication and surgery history,
recommendations from the doctor, etc.
Conclusion:
The above mentioned applications make medical processes faster, more
manageable, and accessible for both patients and healthcare professionals.
And, it has also shortened long queues outside medical units. Technology
is yet evolving, and it only has the best for everyone in the future.
Q.17 What do you mean by artificial Intelligence? Discuss its
applications. (10m)
Artificial intelligence is the simulation of human intelligence processes by
machines, especially computer systems. These processes include learning,
reasoning and self-correction.The word 'AI' was coined by John McCarthy,
an American computer scientist, in 1956 at The Dartmouth Conference
where the discipline was born.
The applications of AI are discussed as follows:
Speech Recognition: Transcribes and transforms human speech into a
format useful for computer applications. Presently used in interactive voice
response systems and mobile applications.
Virtual Agent: A virtual agents serves as an online customer service
representative. It leads an intelligent conversation with users, responds to
their questions and performs adequate non-verbal behavior.
Biometrics: Biometrics uses methods for unique recognition of humans
based upon one or more intrinsic physical or behavioral traits.It is also
used to identify individuals in groups that are under surveillance.
Artificial Intelligence in Healthcare:
a) To make better and faster diagnoses than
humans.
b) To form a hypothesis of patient data
c) To do examination in the laboratory
d) To catalogue medical information
Artificial Intelligence in business:
Robotic process automation is being applied to highly repetitive tasks
normally performed by humans. Chat boxes have already been
incorporated into websites and e companies to provide immediate service
to customers.
AI in education: It automates grading, giving educators more time. It can
also assess students and adapt to their needs, helping them work at their
own pace.
AI in Autonomous vehicles: Just like humans it t works in many ways:
Directing the car to gas station or recharge station when it is running low
on fuel. Adjust the trips directions based on known traffic conditions to
find the quickest route. AI robotics will help us to address t enable disaster
response for dangerous situations.
Conclusion:
Artificial intelligence could play an even more fundamental role in content
creation and also in the software fields in the future. The technology of
artificial can become the future in all the domains of health, environment,
public safety and security.
Q.24 What do you mean by virtual reality ? How is it going to affect
young people's attitudes to violence? (10m)
There is a combination of two terms: virtual’ and ‘reality’. ‘Virtual’ means
near and reality is what we experience as human beings. So the term
‘virtual reality’ basically means ‘near-reality’. In other words, virtual reality
is the term used to describe a three-dimensional, computer generated
environment which can be explored and interacted with by a
person.Virtual reality is an artificial environment that is created with
software and presented to the user in such a way that the user suspends
belief and accepts it as a real environment.
On a computer, virtual reality is primarily experienced through two of the
five senses: sight and sound.The use of VR may affect young people's mind
attitude to violence in the following ways:
a) Video games are capable of causing some form of negative
psychological harm. Due to the violent content playing with toy guns
encourages the younger people for criminal activities.
b) The majority of research in this area has focused on the relationship
between violent content and aggression.It spoils the mental health
like depression due to which they can't control themselves without
doing anti- social activities.
According to the modern research, due to the rapid changes in the field of
computer and internet technology human life has been completely
changed.Basically, the younger people are more active and interested in
the use of different virtual technology And the violent crime among young
people is increasing.
Conclusion:
To control the younger minds from the violence brought by virtual reality,
I think the the manufacturer of war games must take some of the
responsibility.
