Glossary
A
address An identifier defined and used by
a particular protocol and associated
software to distinguish one node from
another.
address resolution In NS networks, the
mapping of node names to IP addresses
and the mapping of IP addresses to subnet
addresses. See also probe protocol, ARP.
alias A character string that is used as an
alternate name for a protocol or a node.
ARP Address Resolution Protocol. ARP
provides IP to LAN station address
resolution for Ethernet nodes on a LAN.
ARPA Advanced Research Projects Agency.
ARPANET The computer network of the
Advanced Research Projects Agency.
ASCII American National Standard Code
for Information Interchange. A character
set using 7-bit code used for information
interchange among data processing and
data communications systems. The
American implementation of International
Alphabet No. 5.
B
binary mode Data transfer scheme in
which no special character processing is
performed. All characters are considered to
be data and are passed through with no
control actions being taken.
bind A system call that assigns a specific
name and unique address to a socket,
turning a socket (which is one end-point of
the connection) into an actual file. Binding
allows servers to register well-known
addresses with the system and each client
to register a specific address for itself. See
also socket and well-known addresses.
bootp Internet Boot Protocol (BOOTP)
used to start, or boot, LAN devices such as
routers, printers, X-terminals, and diskless
workstations.
BOOTPTAB.NET.SYS The configuration
file for the Bootstrap protocol daemon,
bootpd, that contains client and relay
information.
C
client A node on the internetwork that
asks to use one of the Internet Services on
the host. For example, a Telnet client is the
process that uses Telnet protocol to
establish a virtual terminal on your
system.
D
daemon A process that either waitsfor the
occurrence of an event or waits to perform
some specificied task on a periodic basis.
Daemons are typically started once, on
system startup, and they frequently start
other processes to handle service requests.
The Internet daemon inetd is a good
example of such a process.
datagram A message consisting of content
and all of the information needed to deliver
the content between one system and
another. Datagrams are sent using the
User Datagram Protocol, or UDP. See also
UDP.
datagram service A connectionless
service that transmits messages, or
datagrams, from one system to another.
Because datagrams are transmitted
without relying on a pre-established
