1.6. Glossary of Terms
DHCP (Dynamic Host Configuration Protocol) - A standard method for assigning IP addresses
automatically to the devices on a TCP/IP network. As a new device connects, the DHCP server
assigns an IP address from a list of available addresses. The device retains this IP address for the
duration of the session. Once the device disconnects the IP address becomes available for use
again.
DDNS (Dynamic Domain Name System) - Dynamic DNS is a system for allowing an Internet
domain name to be assigned to a varying IP address. This makes it possible for other sites on the
Internet to establish connections to the machine without needing to track the IP address
themselves. A common use is for running server software on a computer that has a dynamic IP
address (e.g., a dial-up connection where a new address is assigned at each connection, or a DSL
service where the address is changed by the ISP occasionally).
DNS (Domain Name System) - A DNS server lets you locate computers on a network or the
Internet (TCP/IP network) by domain name. The DNS server maintains a database of domain
names (host names) and their corresponding IP addresses.
DSL (Digital subscriber line) - Type of broadband connection that brings information to homes
and businesses over ordinary copper telephone lines.
Encryption - Process of obscuring information to make it unreadable without special knowledge.
Information is converted into a code language before it is sent. The receiver has the same software
and decodes the information after it arrives.
