Numeric
802.1x
802.1x defines port-based, network access control used to provide authenticated network access and
automated data encryption key management.
The IEEE 802.1x draft standard offers an effective framework for authenticating and controlling user traffic
to a protected network, as well as dynamically varying encryption keys. 802.1x uses a protocol called EAP
(Extensible Authentication Protocol) and supports multiple authentication methods, such as token cards,
Kerberos, one-time passwords, certificates, and public key authentication. For details on EAP specifically,
refer to IETF's RFC 2284.
802.11a
IEEE specification for wireless networking at 54 Mbps operating in unlicensed radio bands over 5GHz.
802.11b
IEEE specification for wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS)
technology and operating in the unlicensed radio spectrum at 2.5GHz.
802.11g
An IEEE specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS)
technology and operating in the unlicensed radio spectrum at 2.5GHz. 802.11g is backwards compatible
with 802.11b.
10BASE-T
The IEEE specification for 10 Mbps Ethernet over Category 3, 4, or 5 twisted-pair cable.
100BASE-TX
The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable.
