E
Encryption Changing data into a form that cannot be understood by others.  A rule (algorithm) and a key 
(network key) for converting data between a sender and a receiver are determined, and the 
data converted (encrypted) by the sender is returned to its original form (decrypted) by the 
receiver.  In this way, important interactions cannot be deciphered by others.
ESS-ID 
– Extended Service Set ID
A text string that identifies the sender when using wireless LAN.  Since communications use 
wireless LAN radio waves, data can be exchanged with a large number of networks.   Each 
computer or access point (Î page 192) confirms this text string, allowing communications only 
between parties with matching ESS-IDs.
Extended Desktop (Dual 
Display)
