1. Explain following Network Models:
2. OSI Model.

Ans: The Open Systems Interconnection (OSI) reference model was defined by the International Standards Organization (ISO) as a first step towards international standardization. In 1995, it was revised and known as ISO OSI (Open System Interconnection) because it deals with systems that are open for communication with other system. The model has seven layers. They are: physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. Figure 1.5 depicts the OSI reference

 

2. What is multiplexing? Describe the following multiplexing types in detail:
3. Frequency division multiplexing
4. Wavelength division multiplexing

Time division multiplexing

Ans: Multiplexing refers to the process of combining multiple data streams or signals into a single transmission medium or channel. It allows the efficient utilization of the available bandwidth and enables multiple independent signals to share the same communication medium Its Half solved only

3. Explain Integrated Service Digital Network (ISDN) with the following concepts:
4. Goal and structure of ISDN
5. ISDN devices

Ans: a. Goal and structure of ISDN: The Integrated Services Digital Network (ISDN) is a telecommunications network that was developed to provide a comprehensive and integrated solution for transmitting various types of data, including voice, video, and digital information, over digital communication lines. The primary goal of ISDN is to establish a single network that can support multiple services with improved quality, reliability, and flexibility compared to

4. What is Multicast Routing? Describe the following Multicast Routing Protocols in detail:
5. Distance Vector Multicast Routing Protocol (DVMRP)
6. Multicast Open Shortest Path First Protocol (MOSPF)

Ans: In the unicast routing a router’s forwarding table indicate the link to forward a unicast packet for any IP address. But to support multicast, a router must additionally have multicast forwarding tables. These tables indicate those links (possibly more than one) to use to forward the multicast packet based on multicast address. Thus, where unicast forwarding tables collectively

5. What is Symmetric Key Encryption?
6. Data encryption standard (DES)
7. Double DES
8. Triple DES

Ans: Symmetric Key Encryption We have already discussed the basic concepts cryptography. Now we will focus on symmetric key cryptography. It has been quite popular over a number of years. It is referred to by various other terms, such as secret key cryptography or private key

6. What is Multicasting? Describe the following Multicast Transport Protocol concepts.
7. Multicast addressing
8. MTP packet format
9. MTP’s QoS

Ans: Multicasting is a network communication method that allows the transmission of data from one sender to multiple recipients simultaneously. Unlike unicast communication, where data is sent to a single destination, and broadcast communication, where data is sent to all devices on a network,
