Appendix
Broadband
A telecommunications technology that can send different types of data over
the same medium. DSL is a broadband technology.
Broadcast
To send data to all computers on a network.
DHCP
Dynamic Host Configuration Protocol
DHCP automates address assignment and management. When a computer
connects to the LAN, DHCP assigns it an IP address from a shared pool of IP
addresses; after a specified time limit, DHCP returns the address to the pool.
DHCP relay (Dynamic Host Configuration Protocol relay)
A DHCP relay is a computer that forwards DHCP data between computers that
request IP addresses and the DHCP server that assigns the addresses. Each of
the SL6000 / SL6300's interfaces can be configured as a DHCP relay. See
DHCP.
DHCP server (Dynamic Host Configuration Protocol server)
A DHCP server is a computer that is responsible for assigning IP addresses to
the computers on a LAN. See DHCP.
DNS (Domain Name System)
The DNS maps domain names into IP addresses. DNS information is distributed
hierarchically throughout the Internet among computers called DNS servers.
When you start to access a web site, a DNS server looks up the requested
domain name to find its corresponding IP address. If the DNS server cannot
find the IP address, it communicates with higher-level DNS servers to determine
the IP address. See also domain name.
Domain name
A domain name is a user-friendly name used in place of its associated IP address.
For example, www.globespan.net is the domain name associated with IP address
209.191.4.240. Domain names must be unique; their assignment is controlled
by the Internet Corporation for Assigned Names and Numbers (ICANN).
Domain names are a key element of URLs, which identify a specific file at a
web site, e.g., http://www.globespan.net/index.html. See also DNS.
