Explain the following Subnetting Supernetting Backbone IP Address classes X.25 Frame Relay ATM DSL Server Operating system Client DHCP DNS Solution 1.SUBNETTING Subnetting could be a method of dividing giant network into the smaller networks supported layer three information processing address. each pc on network has Associate in Nursing information processing address that represent its location on network. 2 version of information processing addresses square measure offered IPv4 and IPv6. during this article we are going to perform subnetting on IPv4 2.SUPERNETTING Supernetting is that the method of mixing many science networks with a typical network prefix. Super netting was introduced as an answer to the matter of accelerating size in routing tables. Super netting conjointly simplifies the routing method. as an example, the subnetworks 192.60.2.0/24 and 192.60.3.0/24 is combined in to the supernetwork denoted by 192.60.2.0/23. within the supernet, the primary twenty three bits ar the network a part of the address and therefore the different nine bits ar used because the host symbol. So, one address can represent many tiny networks and this could scale back the quantity of entries that ought to be enclosed within the routing table. Typically, supernetting is employed for sophistication C science addresses (addresses starting with 192 to 223 in decimal), and most of the routing protocols support supernetting. Samples of such protocols ar Border entrance Protocol (BGP) and Open Shortest Path 1st (OSPF). But, protocols like Exterior entrance Protocol (EGP) and therefore the Routing info Protocol (RIP) don\'t support super netting 3.BACKBONE A backbone could be a a part of electronic network that interconnects varied items of network, providing a path for the exchange of knowledge between completely different LANs or subnetworks.[1] A backbone will tie along various networks within the same building, in numerous buildings during a field setting, or over wide areas. Normally, the backbone\'s capability is bigger than the networks connected thereto. A large corporation that has several locations might have a backbone network that ties all of the locations along, for instance, if a server cluster has to be accessed by {different|totally completely different|completely different} departments of a corporation that ar settled at different geographical locations. The items of the network connections (for example: LAN, wireless) that bring these departments along is usually mentioned as network backbone. Network congestion is usually taken into thought whereas planning backbones.
