connecting the users on an Ethernet to the Internet through a common broadband medium,
such as a single DSL line, wireless device or cable modem.

NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable a

Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses to clients

the DHCP server program. DHCP leases addresses, for a period of time, which means that
past addresses are “recycled” and made available for future reassignment to other systems.
