My computer is so fast it proves the theory of relativity wrong...

1. A mapping to a memory address of which there are
2^16 or 65536 ports.

2. A host on a Local segment asks for an address and is given one from a range of preconfigured addresses that the DHCP server knows are free.

3. Use the ping command. Ping either a specific host (e.g. the gateway) or the whole network.

4. The output is a representation of what routers the packet has to go through to reach the destination and the time it takes to get there.

Extra: MAC filtering is set up and the hosts MAC is not authorized to connect. Add the MAC to the list of permitted hosts or turn off MAC filtering.

Did I pass???
