RTOS

An operating system implementing components and services that explicitly

 

 

 

offer deterministic responses, and therefore allow the creation of real-time

 

 

 

systems. An RTOS is characterized by the richness of the servicesT

T it

 

 

 

provides, the performance characteristics of those services, and the degree

 

 

 

that those performance characteristics can be controlled by the application

 

 

 

engineer (to satisfy the requirements of the application).

 

 

 

Service Set

An identifier attached to packets sent over the wireless LAN that functions as

 

 

Identifier (SSID)

a "password" for joining a particular radio network (BSS). All radios and

 

 

 

Access Points within the same BSS must use the same SSID, or their

 

 

 

packets will be ignored.

 

 

 

Telnet

A virtual terminal protocol used in the Internet, enabling users to log into a

 

 

 

remote host.

 

 

 

TKIP

Temporal Key Integrity Protocol and is used in encryption. TKIP is an IEEE

 

 

 

802.11i standard and an enhancement to WEP security.

 

 

 

Transceiver

A device for transmitting and receiving packets between the computer and

 

 

 

the medium.

 

 

 

Transmission

A commonly used protocol for establishing and maintaining communications

 

 

Control Protocol

between applications on different computers. TCP provides full-duplex,

 

 

(TCP)

acknowledged, and flow-controlled service to upper-layer protocols and

 

 

 

applications.

 

 

 

Wide Area Network

A communication system of connecting PCs and other computing devices

 

 

(WAN)

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

 

 

 

LANs.

 

 

 

Wi-Fi

Wi-Fi is a name for 802.11 wireless network technology.

 

 

 

Wi-Fi Alliance

A non-profit international association formed in 1999 to certify interoperability

 

 

 

of wireless LAN products based on IEEE 802.11 specification.

 

 

 

Wired Equivalent

A security protocol for wireless LANs defined in the IEEE 802.11 standard.

 

 

Privacy (WEP)

WEP is designed to provide the same level of security as a wired LAN.

 

 

WLAN

Also referred to as a wireless LAN. A type of Local Area Network that uses

 

 

 

high-frequency radio waves rather than wires to communicate between nodes

 

 

 

and provide network connectivity.

 

 

 

WPA

Wi-Fi Protected Access. It addresses all known Wired Equivalent Privacy

 

 

 

(WEP) vulnerabilities. WPA uses RC4 for encryption and TKIP for key

 

 

 

management. It includes a message integrity mechanism commonly called

 

 

 

Michael or MIC.

 

 

 

 

 

 

 

WPA-LEAP

Wi-Fi Protected Access - Light Extensible Authentication Protocol, an

 

 

 

implementation based on the IEEE 802.11i 2004 and IEEE 802.1X 2001

 

 

 

standards, which includes the LEAP protocol for initial key assignment.

 

 

WPA-PSK

Wi-Fi Protected Access - Pre-Shared Key, an implementation based on the

 

 

 

IEEE 802.11i 2004 and IEEE 802.1X 2001 standards, where the PSK is

 

 

 

stored on the client.
