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
- LAN
- Analog and digital data transmission
- High level data link control
ANS:
- a)Local Area Network (LAN)
Local Area Network (LAN) is a small computer network, in which two or more computers are directly connected within a single building or office. It is a small privately owned network, covering a distance of 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 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. (Identifying the correct type – 2 marks, list the different types of networks – 2 mark, explaining the types- 6 marks)
Ans:
Computer network provides powerful medium of communication for employees. Nowadays, Companies are 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:
Asynchronous protocols Asynchronous transmission is a data transfer method in which a collection of data is sent together, spaced by varying time intervals. Each data 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. Downtime is nothing but the time during which a computer or computer system is down, or inoperative due 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
