different routes it could take

transmitted across a network
What is a host address? - ANS ✔The part of an IP address that identifies a specific device.

and payload.
What is a header? - ANS ✔contains info such as packet size, source and destination addresses
What is a payload? - ANS ✔contains data bits sent from source host
