What are the differences between static ip addressing and dynamic ip addressing?

Correct Answer: The internet address( IP address) is 32bits that uniquely and universally defines a host or router on the internet The portion of the IP address that identifies the network is called netid The portion of the IP address that identifies the host or router on the network is called hostid

Correct Answer: TDM is a digital process that can be applied when the data rate capacity of the transmission medium is greater than the data rate required by the sending and receiving devices

Correct Answer: WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing involve light signals transmitted through fiber optics channel

Correct Answer: FDM is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted

Correct Answer: The address resolution protocol(ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address

Correct Answer: The LMHOSTS file is a static method of resolving NetBIOS names to IP addresses in the same way that the HOSTS file is a static method of resolving domain names into IP addresses An LMHOSTS file is a text file that maps NetBIOS names to IP addresses; it must be manually configured and updated

Correct Answer: A scope is a range, or pool, of IP addresses that can be leased to DHCP clients on a given subnet

Correct Answer: DNS servers often must communicate with DNS servers outside of the local network A forwarder is an entry that is used when a DNS server receives DNS queries that it cannot resolve locally It then forwards those requests to external DNS servers for resolution

Correct Answer: RIP is a is an interior gateway protocol that was often used in interior networks and in some degree in internet networks It helps the router adapt to the modifications that are made in a network regarding connections Now it become less used since more efficient protocols were implemented like OSPF or IS-IS It is limited to a lower number of routers, a maximum of fifteen router

Correct Answer: In Stop and wait protocol, sender sends one frame, waits until it receives confirmation from the receiver (okay to go ahead), and then sends the next frame
