VPN
A type of technology designed to increase the security of infor-
mation transferred over the Internet. VPN can work with either
wired or wireless networks, as well as with dial-up connec-
tions over POTS. VPN creates a private encrypted tunnel from
the end user’s computer, through the local wireless network,
through the Internet, all the way to the corporate servers and
database.
WAN
A communication system of connecting PCs and other comput-
ing devices across a large local, regional, national or international
geographic area. Also used to distinguish between phone-based
data networks and Wi-Fi. Phone networks are considered
WANs and Wi-Fi networks are considered Wireless Local Area
Networks (WLANs).
WEP
Basic wireless security provided by Wi-Fi. In some instances,
WEP may be all a home or small-business user needs to protect
wireless data. WEP is available in 40-bit (also called 64-bit), or
in 108-bit (also called 128-bit) encryption modes. As 108-bit
encryption provides a longer algorithm that takes longer to
decode, it can provide better security than basic 40-bit (64-bit)
encryption.
Wi-Fi
Wireless Fidelity: An interoperability certification for wireless
local area network (LAN) products based on the Institute of
Electrical and Electronics Engineers (IEEE) 802.11 standard.
