What technology takes packets and breaks them out into smaller packets and send them over the network?
packet switching
Which layer determines the route a packet takes from sender to sender to receiver?
Network Layer
Define Network device latency?
Latency is the time a frame or a packet takes to travel from the source to the destination.
What is the difference between end-to-end delay and packet jitter?
End-to-end delay is the time it takes a packet to travel across the network from source to destination. Delay jitter is the fluctuation of end-to-end delay from packet to the next packet.
You are a network engineer working to isolate problems at the data-link layer with an end-system running a MAC OS X You want to view the path a packet takes through the network to 10 215 34 124?
traceroute 10.215.34.124
What utility attempts to trace the path that a packet takes through the network?
tracert (traceroute on unix-like systems) will do this. use the command tracert /? for more information on options for this command, such as the maximum number of "hops".
Each route that a packet takes to reach the next device is called what?
A hop
What is the difference between end to end delay and packet jitter?
End-to-end delay refers to the total time taken for a packet to travel from the source to the destination. Packet jitter, on the other hand, is the variation in delay between packets caused by network congestion, routing changes, or varying traffic patterns. In essence, end-to-end delay is the total time taken, while packet jitter measures the variability in that delay.
What happen to the packet when it is received by data link layer?
here in data link the actual physical mean of coneection will takes place between source and destination hosts......once packet from network layer enter into data link layer the trailer is gonna add to packet also the MAC(media access control) address of destination host will be determined............once source host get the information of MAC.......its gonna add to packet along with packet then it will be called by name frame....switch will work in this layer and the protocol used are ARP and RARP........
Write difference in the form of a table between Ping and Trace Route command?
The Ping command sends a small packet of data to a destination IP address and waits for a response. It measures the time it takes for a packet to travel from the source to the destination. This command is typically used to check if a network device is online and responding to requests. On the other hand, the Trace Route command sends a series of packets to a destination IP address and tracks the route that each packet takes. It identifies each router or hop that a packet goes through on its way to the destination. This command can be used to diagnose network latency issues or identify where data is being lost. While the Ping command only provides information on the time it takes for a packet to reach the destination, the Trace Route command provides more detailed information on the network path and any delays or losses that occur along the way. In summary, both the Ping and Trace Route commands can be useful in troubleshooting network issues, but they serve different purposes. The Ping command is a simple tool for testing connectivity to a destination device, while the Trace Route command provides more detailed information on the network path and any issues that may be occurring.
Wic address is used by the router to direct a packet between networks?
The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets. The information is stored on a per-network basis. When the router receives an IP packet, it consults the routing table, to see what is the next-hop address, and through which interface it must send the packet.The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets.

What information do routers use to forward a message?
Entire chapters in the Cisco Networking Academy are dedicated to this topic. But basically, a router looks at the IP packet, and compares it to its routing table. The routing table says, for example, "Every packet for the destination network 10.0.5.0 /24 should be sent out of port Ethernet 2/1, next-hop address is 10.0.7.2". "/24" in this case means that the first 24 bits must match. The routing table itself is maintained manually (static routes), or updated through a routing protocol from neighboring routers.
