Group ‘B’
Short questions: 7*4=28
1. How
computer network reduces cost of operation? Explain.
Ans: Computer network is the
inter-connection of computer together. In the computer network, all the
computer have the capacity to do more work. If a company has a 20 computer
systems, and if it purchases the individual peripheral devices like printer,
scanner, etc, it has to invest a lot. But if it does the networking, then it
has to buy a single piece of peripheral device and can share commonly together
in the network. Hence, it has no need to invest a lot and reduces the cost of
operation.
2.
What
are the advantages of using E-mail?
Ans: Some of the advantages of E-mail are
given below:
·
Emails are
delivered extremely fast when compared to traditional post.
·
Emails can be

4. What
do you know about software piracy and digital signature?
Ans: Software Piracy
means downloading and using of any software without paying money or giving
compensation to the owner of the software is known as software piracy. or The definition of
software piracy is the "unauthorized copying or distribution of
copyrighted software.
A
digital signature is a mathematical technique used to validate the authenticity
and integrity of a message, software or digital document. As the digital equivalent
of a handwritten signature or stamped seal, a digital signature offers far more
inherent security, and it is intended to solve the problem of tampering and
impersonation in digital communications.
5. Define
Operating system. Explain the types of operating system on the basis of user.
Ans: One of the most important software
for computer system is known as Operating system. Computer cannot operate
without it.
Operating
system is of two types on the basis of user. They are Single user and Multi-user
i. Single User:
It is a type of OS that only allows a
single user to use a computer at a time. This type of OS can be used on a
standalone computer system. This type computer system is cheaper than other
computer. It can be purchased by all.
ii. Multi-User:
It
is a type of OS that only allows many user to use a computer at a time. This
type of OS can be used on a server computer system. It can be used for
networking type of work. This type computer system is expensive than other
computer. It can’t be purchased by all.
6. Write
the short notes on:
a) Social
network
A
social network is a website that allows people with similar interests to come
together and share information, photos and videos. People engaged in social
networking may be doing so as a personal or a business endeavor. Those
who engage on social network sites as a personal endeavor interact by using
various forms of media to discuss their lives and interests. The most popular
social networks for this type of familiar interaction include Facebook, viber,
skype, whatsaap, wechat and Twitter.
b) ENIAC
The full form of ENIAC
is Electronic Numerical Integrator and Computer, the ENIAC was
the first electronic computer used for general purposes, such as solving
numerical problems. It was invented by John Presper Eckert and John Mauchly at the University of Pennsylvania to
calculate artillery firing tables for the United States Army's Ballistic
Research Laboratory.

2. Classify
the computer on the basis of size, explain each of them briefly.
Ans: Computer can be categorized on the basis of size
in 4 groups. They are explained below:
i. Super Computer
Super Computer is one of the
biggest computers on the basis of size. It is one of the most powerful
computer. It is most expensive computer in the world. It is used for scientific
research and weather forecasting. It consumed large amount of electricity and
produced large amount of heat. It was developed in first generation. It used
Vacuum tube as a main component.
ii. Mainframe Computer
Mainframes are a type of computer
that generally are known for their large size, amount of storage, processing
power and high level of reliability. It used Transistor as the main component. They
are primarily used by large organizations for mission-critical applications
requiring high volumes of data processing. They are mainly used by government institutions and large companies for tasks such as census, industry and consumer statistics, enterprise resource planning, and
financial transaction processing. Mainframe computers are specially used
as servers on the World
Wide Web (WWW).
iii. Mini Computer
A
minicomputer is a type of computer that possesses most of the features and
capabilities of a large computer but is smaller in physical size. It used Transistor as the main component.
A minicomputer fills the space
between the mainframe and microcomputer, and is smaller than the former but
larger than the latter. Minicomputers are mainly used as small or mid-range
servers operating business and scientific applications. However, the use of the
term minicomputer has diminished and has merged with servers. It is also known
as Mid-ranged computer.
iv. Micro Computer
Micro computer is the
smallest computer among super, mainframe and mini computers. It used
Mircro-processor as its main component. Microcomputers became popular in the 1970s and
1980s with the advent of increasingly powerful microprocessors. The
predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more
expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom
microprocessors as their CPUs).
