TCP/IP
The underlying technology behind the Internet and communications
between computers in a network. The first part, TCP, is the transport
part, which matches the size of the messages on either end and
guarantees that the correct message has been received. The IP part is
the user’s computer address on a network. Every computer in a TCP/
IP network has its own IP address that is either dynamically assigned
at startup or permanently assigned. All TCP/IP messages contain the
address of the destination network as well as the address of the
destination station. This enables TCP/IP messages to be transmitted
to multiple networks (subnets) within an organization or worldwide.
VoIP
Voice transmission using Internet Protocol to create digital packets
distributed over the Internet. VoIP can be less expensive than voice
transmission using standard analog packets over POTS (Plain Old
Telephone Service).
VPN
A type of technology designed to increase the security of information
transferred over the Internet. VPN can work with either wired
or wireless networks, as well as with dial-up connections 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 computing
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.
