- Glossary
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.
Restart
See Reset.
Resume
To proceed after interruption. In your notebook 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 can not be changed by your notebook and does not require power to maintain it.
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.
