DNS Server Domain Name Server. The computer you use to access the
DNS to allow you to contact other computers on the Internet.
The server keeps a database of host computers and their IP
addresses.
Domain Name The unique name that identifies an Internet site. Domain
Names always have 2 or more parts, separated by dots. The
part on the left is the most specific, and the part on the right is
the most general. A given machine may have more than one
Domain Name but a given Domain Name points to only one
machine. For example, the domain names: matisse.net,
mail.matisse.net, workshop.matisse.net can all refer to the
same machine, but each domain name can refer to no more
than one machine. Usually, all of the machines on a given
Network will have the same thing as the right-hand portion of
their Domain Names (matisse.net in the examples above). It
is also possible for a Domain Name to exist but not be
connected to an actual machine. This is often done so that a
group or business can have an Internet e-mail address
without having to establish a real Internet site. In these cases,
some real Internet machine must handle the mail on behalf of
the listed Domain Name.
Escape Sequence A sequence of special characters that sends a command to a
device or program. Typically, an escape sequence begins with
an escape character, but this is not universally true.
An escape sequence is commonly used when the computer
and the peripheral have only a single channel in which to
send information back and forth. If the device in question is
"dumb" and can only do one thing with the information being
sent to it (for instance, print it) then there is no need for an
escape sequence. However most devices have more than one
capability, and thus need some way to tell data from
commands.
Ethernet A LAN cable-and-access protocol that uses twisted-pair or
coaxial cables and CSMA/CD (Carrier Sense Multiple
Access with Collision Detection), a method for sharing
