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.
