This document is an announcement for MBA students offering fully solved assignments for the Spring 2016 semester, including topics on computer networks. It includes question prompts and brief answers on subjects like OSI model, subnetting, DNS, DWDM, and network management protocols. Students can reach out via email or phone for further assistance.
![Question.3. Write short notes on the following:
a. Subnet
Answer:A subnetwork,orsubnet,isalogical,visible subdivision of an IP network.[1] The practice of
dividing a network into two or more networks is called subnetting.
Computers that belong to a subnet are addressed with a common, identical, most-significant bit-
groupin theirIPaddress.Thisresultsinthe logical divisionof anIPaddressintotwofields,anetwork
or routingprefix andthe restfieldorhostidentifier. The rest field is an identifier for a specific host
or network interface.
b. Super netting
Answer:A supernetwork, or supernet, is an Internet Protocol (IP) network that is formed from the
combinationof twoor more networks (or subnets) with a common Classless Inter-Domain Routing
(CIDR) prefix. The new routing prefix for the combined network aggregates the prefixes of the
constituent
c. Subnet masks
Answer:An IP address has two components, the network address and the host address. A subnet
maskseparatesthe IP addressintothe network and host addresses (<network><host>). Subnetting
further divides the
d. Dynamic NAT
Answer:It is a type of NAT in which a private IP address is mapped to a public IP address drawing
from a pool of registered (public) IP addresses. Typically, the NAT router in a network will keep a
table of registeredIPaddresses, and when a private IP address requests access to the Internet, the
routerchoosesan IPaddressfromthe table that is not at the time being used by another private IP
address. Dynamic NAT helps to secure

Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme. Question.1. Explain the concept of computer networks. Briefly explain the different types of networks. Answer:A computer network is a set of connected computers. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable,or wirelessly through radio waves. Connected computers can share resources, like access to the Internet,printers,file servers,andothers.A networkisamultipurposeconnection,which allows a single computer to do more. Types of Network Connections Question.2. Write a brief note on seven layered OSI reference model. Explain the role of each layer. Answer:The Open System Interconnection (OSI) model defines a networking framework to implementprotocolsin sevenlayers.Inthe OSImodel,control is passed from one layer to the next, startingat the applicationlayerinone station,andproceedingtothe bottomlayer,overthe channel to the next station and back up the hierarchy.

- 3. Answer:DNS is an abbreviation for Domain Name System, a system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks,suchasthe Internet,tolocate computersandservicesthroughuser-friendlynames.When a user entersaDNS name inan application,DNSservicescanresolve the name to other information associated with the name, such as an IP address. Question.4. What is Dense Wavelength Division Multiplexing (DWDM)? What are the pros and cons ofDWDM? Answer:DWDMincreasesthe bandwidthof anoptical fiberbymultiplexing several wavelengths (or colors) onto it. Even though it costs more than CWDM, it is currently the most popular WDM technology because it offers the most capacity. By providing channel spacings of 50 GHz (0.4 nm), 100 GHz (0.8 nm) or 200 GHz (1.6 nm), several hundreds of wavelengths can be placed on a single fiber. Most typical DWDM systems use 40 or 80 channels, although this number can be as high as 160. Question.5. Explain the working of Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Protocol. Answer:Carriersense multiple access with collision detection (CSMA/CD) is a media access control methodusedmostnotablyinlocal areanetworkingusingearlyEthernettechnology.It uses a carrier sensingscheme inwhicha transmittingdatastationdetectsothersignalswhiletransmittingaframe, and stopstransmittingthatframe,transmitsajam signal,and then waits for a random time interval before trying to resend the frame. CSMA/CD is a modification of pure carrier sense multiple access (CSMA). CSMA/CD is used to improve CSMA performance by terminating Question.6. Briefly explain the functions of network management model. Answer:Networkmanagementmeansdifferentthingstodifferentpeople.Insome cases, it involves a solitary network consultant monitoring network activity with an outdated protocol analyzer. In othercases,networkmanagementinvolvesadistributeddatabase, autopolling of network devices, and high-end workstations generating real-time graphical views of network topology changes and traffic. In general, network management is a service that employs a variety of tools, applications, and devices to assist human network managers in Dear students get fully solved assignments Send your semester & Specialization name to our mail id : help.mbaassignments@gmail.com
