SDRAM

Synchronous Dynamic Random Access Memory.

Serial Port

A connection to another device through which data is transferred one bit at a time on a single wire with

any other wires only for control of the device not for transfer of data.

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. The SSID

differentiates one WLAN from another, 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.
