What are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
What action is taken by a host on an Ethernet network when the host attempts to contact a remote host on another network?
The packet is sent using the IP address and MAC address of the default gateway.
A subnet mask separates?
A submask is designed to separate the network id portion of an IP address from the host or client portion. This helps a router determine whether the packet needs to be forwarded to another network.
How will a packet that is sent from host A to host B be handled by the devices on the network?

How does ANDing help an originating host?
An originating host must determine if a packet should be sent directly to a host in the local network or be directed to the gateway.
What does the local host use to determine the destination network ID of a particular packet?
the address Class
Why Network virtual terminal is needed in remote login?
Network Virtual Terminal, is a software version of a physical terminal and allows a user to log on to a remote host .So the application created emulation of terminal at the remote host .Users computer talks to the software terminal which in turn talks to the host & vice verse .Remote host believes it is communication with one of its own terminals and allow you to log on
Why do routers use anding?
ANDing is used by a router, to see if the host which has to be contacted, is on the local network of the router, or a remote network.
Why does a network host need to broadcast an ARP request?
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message. Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
What is the meaning of remote host in computer?
a computer that resides in some distant location from which data can be retrieved .It typially refers to a server in a private network or public network.
How will a broadcast frame that is sent by a host PC be handled on the net?
The broadcast will be received by all devices in the same network, but will not be forwarded outside the network (routers do not forward broadcast messages). So for the Internet, for example, you do not see broadcast packets.
