RAM
Random Access Memory. A hardware component of your LIFEBOOK Tablet PC that holds binary information (both
program and data) as long as it has the proper power applied to it.
RAM Module
A printed circuit card with memory and associated circuitry which allows the user to add additional memory to the
computer without special tools.
Reset
The act of reloading the operating system. A reset erases all information stored in RAM.
Resume
To proceed after interruption. In your Tablet PC this refers to returning to active operation after having been in one of
the suspension states.
ROM
Read Only Memory. A form of memory in which information is stored by physically altering the material. Data stored
in this way cannot be changed by your Tablet PC and does not require power to maintain it.
SDRAM
Synchronous Dynamic Random Access Memory.
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.
