Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme. Q. 1. Explain the working of Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Protocol. Answer:CarrierSense Multiple AccessWithCollisionDetection(CSMA/CD) is a media access control methodusedmostnotablyinlocal areanetworkingusingearlyEthernettechnology.It uses a carrier sensingscheme inwhichatransmittingdatastationdetectsothersignalswhiletransmittingaframe, 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 Q. 2. Differentiate between seven layered OSI reference model and four layered OSI reference model. Answer:The OpenSystemsInterconnectionmodel(OSI) isaconceptual model thatcharacterizesand standardizes the internal functions of a communication system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO), maintained by the identification ISO/IEC 7498-1. Define seven layered

Computers that belong to a subnet are addressed with b. Super netting:A supernetwork, or supernet, is an Internet Protocol (IP) network that is formed fromthe combinationof twoormore networks(orsubnets) with a common Classless Inter-Domain Routing (CIDR) prefix. The new c. Subnet masks: A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host d. Dynamic NAT: DynamicNATisatype of NATin whicha private IPaddress 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 e. Domain Name System:The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates Q. 4. What is DWDM? What are the pros and cons of DWDM Answer:Dense wavelength division multiplexing (DWDM) is a technology that puts data from differentsources together on an optical fiber, with each signal carried at the same time on its own separate lightwavelength.UsingDWDM, upto 80 (and theoreticallymore) separate wavelengths or channels of data can be multiplexed into a lightstream transmitted on a single optical fiber. Each channel carries a time Q. 5. Briefly explain the networking applications in government sector Listing the objectives About networking applications – understanding the networking for government sector and listing the websites and portals and explaining for them Answer:Whenwe speakof applications,we simplymeanthe things a computer or other tool can be usedfor. You are familiar with many applications, like word processing, email, Web browsing, and spreadsheet processing.
