Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Q.1. Write short notes on:
a. LAN
b. Analog and digital data transmission
c. High level data link control
Ans : a) Local Area Network (LAN):
These typesof computernetworks connect network devices over a relatively short distance. Quite
often, a networked office building, home or school contains a single LAN although it is normal to
come across a building that
b. Analog and digital data transmission :
Analog data transmission:
Analog(oranalogue) transmissionisa transmission method of conveying voice, data, image, signal
or video information using a continuous signal which varies in amplitude, phase, or some other
property in proportion to that of a variable. It could
c. High level data link control:
High-Level Data Link Control (HDLC) is a bit-oriented code-transparent synchronous data link layer
protocol developed by the International Organization for Standardization (ISO). The original ISO
standards for HDLC are:

2. ISO 3309 – Frame Structure
Q2. Videoconferencing is used to conduct meetings with the people who 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.
Answer :Videoconferencing type :
The wide area network (WAN) is a critical component of the infrastructure supporting video
conferencing
Conducting a conference between two or more participants at different sites by using computer
networks to transmit audio and video data. For example, a point-to-point (two-person) video
conferencing system works much like a video telephone. Each participant has a video camera,
microphone, and speakers mounted
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.
Answer : Different types of protocols :
Two main classes of protocols are :
File retrieval protocols
Thistype of service was one of the earliest ways of retrieving information from computers connected to
the Internet. You could view the names of the files stored on the serving computer, but you didn't have
any type of graphicsand sometimes no description of a file's content. You would need to have advanced
knowledge of which files contained the information you sought.
FTP (File Transfer Protocol)
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: Different types of ISDN :
IntegratedservicesreferstoISDN'sabilitytodeliver at minimum two simultaneous connections, in
any combinationof data,voice,video,andfax,overasingle line.Multipledevicescanbe attached to
the line, and used as needed. That means an ISDN line can take care of most people's complete
communications needs (apart from
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
solutionthat will eliminate downtime.Downtime isnothing but the time during which a computer
or computer system isdown, or inoperative due to hardware or software failure.We also needthe
flexibilityinquickresponse to both the developmentincustomer 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

3. deliverthe 24X7X365 reliability,andspeedthat outsourcingcustomers demand,it has enabledthe
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.
Ans : The problems faced by ABC Company after reading the SLM
The importantissue toaddresswhile choosingconnectivitysolutionsis,whetherapplication servers
are beingconnectedto 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 solution, a leading network storage infrastructure software provider,
helped ABC Company to achieve their goal by
Q6. How are the differenttopologiesofcomputernetworks arranged? Explain the working of each
of them
Answer :Topologies :
Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer or
biological network. Essentially,itisthe topological structure of anetwork,and may be depicted physically
or logically. Physical topology refers to the placement of the network's various components, including
device location and cable installation, while logical topology shows how data flows within a network,
regardlessof itsphysical design.Distancesbetweennodes,physical interconnections, transmission rates,
and/or signal types may differ between two
