Glossary E-3
DNS Server A server that contains both the English and numerical addresses of all computers
connected to the Internet. When you specify an e-mail or IP address using the
“English” domain name, the DNS server will return the corresponding numeric
address.
Domain Name A domain name locates an organization or other entity on the Internet.
Driver A program that a computer uses to control the operation of a peripheral device,
such as a keyboard, modem, monitor, card, or cable.
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
Service Set)
A group of wireless clients and multiple APs using the same ID (ESSID) form an
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.
