Master of Business Administration- MBA Semester 3
MI0035 –Computer Networks
(Book ID: B1481)
Assignment (60 marks)
Note: Answer all questions. Kindly note that answers for 10 marks questions should
not exceed
400 word. Each question is followed by evaluation scheme.
Q.1. Write short notes on: 2, 3, 5
a. LAN
b. Analog and digital data transmission
c. High level data link control
ANS:
a) Local Area Network (LAN)
Local Area Network (LAN) is a small computer network, in which two or morecomputers
are directly connected within a single building or office. It is a small privately owned
network, covering a distanceof up to 10km that helps to connect personal computers or
workstations to share information and resources. LANs use
Q2. Videoconferencing is used to conduct meetings with the peoplewho are located in
far distance. Videoconferencing is an example of which type of computer networks?
Explain in detail the different types of networks with example. (Identifying the correct
type – 2 marks, list the different types of networks – 2 mark, explaining the types- 6
marks)
Ans:

2. Computer network provides powerful medium of communication for employees. Nowadays,
Companiesare using electronic mail for its daily communication. Apart from email, companies are
usingvideoconferencing as a computer-assisted communication medium. This videoconferencing
helps companies to conduct meetings with people, who are located at a far distance
Q3. A protocol helps in establishing the communication between two systems.
Protocols are mainly divided into asynchronous and synchronous protocols. List and
describe in detail the different types of protocols that are classified under the two
main protocols. (list and correct differentiating of protocols under the two main types
– 5 marks, explanation- 5 marks) 10 marks
Ans:
Asynchronousprotocols Asynchronoustransmissionis a data transfer method in which a collection
of data issenttogether,spacedbyvaryingtime intervals.Eachdata character is preceded by a start-
bit and is followed by an end-bit to inform the receiver where the character begins and ends.
Asynchronous protocols are the communication protocols which are used in asynchronous
transmission. An asynchronous protocol sends data to
Q.4. Integrated Services for Digital Network (ISDN) is a set of communication
standards for
Simultaneous digital transmission of voice, video, data, and other network services
over the traditional circuits of the public switched telephone network. It was first
defined in 1988 in the CCITT red book. Explain the different types of ISDN with their
features and advantages for each one of them. (Explaining Two different types ,
Features of both of them , Advantages of both of them) 2,4,4
ANS:
ISDN channels
The term ISDN channel means the passage or transmission of signalling and user
information in a single direction. The three basic ISDN channels are Data channel (D
channel), Bearer channel (B channel), and Hybrid channel (H channel).
Q.5. ABC company is an internet service provider. The main goal of ABC is to provide
24 X7X365 storage capacity, storage management and internet service to the
customers. It now needs a solution that will eliminate downtime.Downtimeis nothing
but the time during which a computer or computer system is down, or inoperative due

3. to hardware or software failure. We also need the flexibility in quick response to both
the development in customer base and additional capacity and service demands of the
customers. ABC company took the help of network storage infrastructure software
provider to achieve their goals by providing support for end to end redundancy and
bondless scalability. By creating a scalable storage network with the ability to
confidentially deliver the 24X7X365 reliability, and speed that outsourcing customers
demand, it has enabled the ISP/SSP to attract and retain customers and substantially
build its business. As the same time, the solution has effectively lowered ABC
company’s total cost of ownership for its entire storage solution: the IP Stor/CNP
union has enabled a painless, flexible cost effective, scalable solution. The
complementary IP Stor/CNT solution has allowed to its customers easily and cost-
effectively. a. What were the problem which ABC Company was facing before
consulting network storage infrastructure software provider? b. What were the
benefits of implementing a scalable storage network? c. List the different classes of
ISPs and their applications. ( Mentioning the problems faced by ABC company after
reading the SLM, Listing the benefits, Listing the different classes of ISP and their
applications) 2,3,5
ANS:
The problems faced by ABC Company after reading the SLM
The important issue to address while choosing connectivity solutions is, whether
application servers are being connected to storage or disparate networks are being
interconnected. The key factors to be considered are elimination of single points of
failure, high scalability, and ease of set up. The FalcoStor’s IP Stor software
Q6. How are the different topologies of computer networks arranged? Explain the
working of each of them (listing the different topologies with examples – 2 marks,
explanation- 4 marks, diagrams- 4 marks) 10 marks
Ans:
Types of topology :
1) Bus topology
2) Ring topology
3) Star topology
4) Tree topology
