Shared key authentication
802.11 network authentication method in which the AP sends the client device a challenge text packet
that the client must then encrypt with the correct WEP key and return to the AP. If the client has the
wrong key or no key, authentication will fail and the client will not be allowed to associate with the
AP. Shared key authentication is not considered secure, because a hacker who detects both the clear-
text challenge and the same challenge encrypted with a WEP key can decipher the key.
Sleep
To make inoperative for a period of time. Your LifeBook Tablet PC uses various suspension states to
reduce power consumption and prolong the charge of your battery.
SSID
Service Set Identifier, a 32-character unique identifier attached to the header of packets sent over a
WLAN that acts as a password when a mobile device tries to connect to the BSS. SSID differentiates
between WLANs, so all access points and all devices attempting to connect to a specific WLAN must
use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique
SSID. Because the SSID is broadcast in plain text, it does not supply any security to the network.
Status Indicator
A display which reports the condition of some portion of your hardware. On your LifeBook Tablet PC
this is an LCD screen just above the keyboard.
Stereo (audio)
A system using two channels to process sound from two different sources.
Subnet mask
TCP-IP network is controlled by being divided into multiple smaller networks (subnets). IP address
consists of the subnet address and the address of each computer. Subnet mask defines how many bits
of IP address comprise the subnet address. The same value shall be set among computers
communicating with each other.
