Explanation:
Network sniffer is a computer program or a piece of computer hardware that can intercept and log
traffic passing over a digital network or part of a network. As data streams flow across the network,
the sniffer captures each packet and, if needed, decodes the packet’s raw data, showing the
values of various fields in the packet, and analyzes its content according to the appropriate RFC or
other specifications.
