Explanation:
A packet or network sniffer is a general term for programs or devices
able to examine traffic on a LAN segment. Traffic that is being transferred over a
network medium is transmitted as electrical signals, encoded in binary
representation. The sniffer has to have a protocol-analysis capability to recognize
the different protocol values to properly interpret their meaning.
