ATM address
A 20-byte (the bytes are often referred to as octets) number that uniquely
identifies an ATM endpoint. The first 13 bytes are assigned by the switch and
are called the switch prefix; the remaining 7 bytes (made up of a 6-byte end
system identifier and a 1-byte selector) are assigned by the local host.
domain name
A name that identifies a logical group of computers. It is a text string
composed of letters (a-z and A-Z), digits (0-9) and hyphens (-) (for example,
eng
). A fully-qualified domain name is composed of the local domain and all
of its ancestor domains leading to the root domain, separated by periods and
ending in a period (for example,
eng.sun.com.)
. A partially-qualified
domain name is the local domain name and some number of ancestor domains
separated by periods (for example,
eng.sun
). When a partial domain name is
used, it is assumed to be within the current domain or within one of the
ancestor domains of the current domain.
DNS
Domain Name System. A network information service that provides
information about hosts within the domain name system. It is mainly used for
name resolution, that is, to provide host addresses that correspond to host
names. It can also be used to provide other information about hosts such as
aliases or mail servers.
