Page 7: About Smart Cards And Fingerprint Readers
Using smart cards can improve computer security by combining something a user has (the smart card) with something only the user should know (a PIN) to provide more secure user-authentication than passwords alone. The fingerprint reader is a device that you can use to help keep your Dell™ computer secure. The reader is a strip sensor located on a peripheral device for your computer. When you slide your finger over the reader, it uses your unique fingerprint to authenticate your user identity.

This section provides an overview of the RAID configuration that you may have selected when you purchased your computer. A number of RAID configurations are available in the computer industry for different types of uses. Your Dell computer supports RAID level 0 and RAID level 1. A RAID level 0 configuration is recommended for high-performance programs, while RAID level 1 is recommended for users that desire a high level of data integrity.
Page 20: Raid Level 1 Configuration
RAID Level 1 Configuration RAID level 1 uses a data-redundancy storage technique known as mirroring to enhance data integrity. When data is written to the primary drive, the data is also duplicated, or mirrored, on the second drive in the configuration. If a drive failure occurs, subsequent read and write operations are directed to the surviving drive.
