DNS Server A server that contains both the English and numerical addresses of all computers

DSSS (Direct
Sequence Spread
Spectrum) A digital modulation technique that spreads data transmissions across the entire
available frequency band in a pre-arranged scheme. Under DSSS, each bit of data
to be transmitted is encoded with a redundant pattern called a chip. The chipping
code is known only to the sending and receiving clients, making it difficult for an
intruder to intercept and decipher the encoded wireless data. DSSS is used in IEEE
802.11b networks.
Dynamic IP address See DHCP (Dynamic Host Configuration Protocol).
Encryption A procedure to convert a file from its original form to one that can be read only by
the intended recipient.
ESS (Extended

ESS.
ESSID (Extended
Service Set Identity) An ASCII string that is used by a wireless network. Wireless clients with a different
ESSID from your network’s ESSID cannot connect to your network. An ESSID can
be as long as 32 characters.
