A device that forwards Internet traffic from your local area network.
¾
DHCP -
A networking protocol that allows administrators to assign temporary IP addresses to
network computers by “leasing” an IP address to a user for a limited amount of time, instead
of assigning permanent IP addresses.

IEEE 802.11b -
The IEEE 802.11b standard specifies a wireless networking at 11 Mbps using
direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio
spectrum at 2.4GHz, and WEP encryption for security. IEEE 802.11b networks are also
referred to as Wi-Fi networks.
¾
IEEE 802.11g -
Specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology, using OFDM modulation and operating in the
unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 8021b devices,
and WEP encryption for security.
¾
Infrastructure Network -
An infrastructure network is a group of computers or other devices,
each with a wireless adapter, connected as an IEEE 802.11 wireless LAN. In infrastructure
mode, the wireless devices communicate with each other and to a wired network by first going
through an access point. An infrastructure wireless network connected to a wired network is
referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is
referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a corporation
scale, or when it is necessary to connect the wired and wireless networks.
