Wireless Terminology (Cont.)
Subnet Mask
A Subnet mask, which may be a part of the TCP/IP information provided by
your ISP, is a set of four numbers configured like an IP Address. It is used to
create IP Address numbers used only within a particular network (as opposed
to valid IP Address numbers recognized by the Internet.
TCP/IP
Transmission Control Protocol/Internet Protocol. This is the standard protocol
for data transmission over the Internet.
TKIP
The TKIP (Temporal Key Integrity Protocol), pronounced "teekip", is part of the
IEEE 802.11i encryption standard for wireless LANs. TKIP is the next
generation of WEP used to secure 802.11 wireless LANs.TKIP provides
per-packet key mixing, a message integrity check and a re-keying mechanism,
thus fixing the flaws of WEP.
WAN
A wide area network (WAN) is a geographically dispersed telecommunications
network. The term distinguishes a broader telecommunication structure from a
local area network. A wide area network may be privately owned or rented, but
the term usually connotes the inclusion of public (shared user) networks. An
intermediate form of network in terms of geography is a metropolitan area
network.
Wireless Access point (WAP)
A wireless LAN transceiver or "base station" that can connect a wired LAN to
one or many wireless devices. Access points can also bridge to each other.
There are various types of access points and base stations used in both
wireless and wired networks. These include bridges, hubs, switches, routers
and gateways. The differences between them are not always precise, because
certain capabilities associated with one can also be added to another. For
example, a router can do bridging, and a hub may also be a switch. But they
are all involved in making sure data is transferred from one location to another.
A bridge connects devices that all use the same kind of protocol. A router can
connect networks that use differing protocols. It also reads the addresses
included in the packets and routes them to the appropriate computer station,
working with any other routers in the network to choose the best path to send
the packets on. A wireless hub or access point adds a few capabilities such as
roaming and provides a network connection to a variety of clients, but it does
not allocate bandwidth. A switch is a hub that has extra intelligence: It can read
the address of a packet and send it to the appropriate computer station. A
wireless gateway is an access point that provides additional capabilities such
as NAT routing, DHCP, firewalls, security, etc.
WEP
WEP (Wired Equivalent Privacy) is 802.11's optional encryption standard
implemented in the MAC layer that most radio network interface card (NIC) and
access point vendors support. 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 An
interoperability certification for wireless local area network (LAN) products
based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11
standard.
WLAN
Also referred to as LAN. A type of local-area network that uses high-frequency
radio waves rather than wires to communicate between nodes.
WPA
WPA is a standards-based, interoperable security specification that utilizes
Temporal Key Integrity Protocol to provide improved over-the-air encryption of
wireless data.
