When a packet traverses a network each router is a...?
hop
When a packet traverses a network each router is a what?
hop
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 is packet fragmentation?
If a device receives a packet which is larger than it is set to forward, it will split the packet and pad the part packet with zeros. This increases the number of packets transmitted on the next hop.
What is the purpose of TTL field in ip header?
It's a time-to-live field designating that the packet is OK to forward from one device to another for a certain amount of time. If the packet gets caught in a routing loop, it won't just go back and forth forever. If that were allowed to happen, many other packets would be doing the same thing, just being mis-routed back and forth between the confused devices, until the available bandwidth on the link was saturated. The TTL assures that the packet will not be forwarded by the very next routing device that reads the packet's TTL field and sees that its TTL has expired. The packet would be discarded at that point.
Which device should be used for routing a packet to a remote network?
router
Each route that a packet takes to reach the next device is called what?
A hop
Which device will send a response to the initial tracert packet from PC1?
LON don
Why Hub comes on Physical Layer device?
A hub is a layer 1 (physical) device because it does not use any part of the packet header to direct the packet to the right destination, it just broadcasts to all connected computers.
If the tcp protocol did not receive an acknowledgement?
If the sending device does not receive an acknowledgement for a packet, the packet will be retransmitted.
What is used to reassemble the packets in the correct order at the destination device in a packet-switched data network?
In a packet-switched data network, what is used to reassemble the packets in the correct order at the destination device?
Which is a device that forwards packets between networks by processing the routing information included in the packet?
A router is a networking device that forwards data on a network.
