Network sniffing and analysis has
become a critical and necessary element of work for systems administrators,
network admin, network engineers, security analysts, and many other niches
within the realm of information technology. Wireshark is a free tool that
allows you to quickly investigate connectivity and application problems.
Download, install, and capture some local traffic from your home network.
What data link communications do you see taking place? Does anyone see a term

Please take a look in the
Webliography for the link titled Wireshark.
