Glossary
Socket: Addressable entities
that are at either end of an
Interprocess Communication
connection. A socket is
identified by a socket
descriptor. A program can write
data to and read data from a
socket, just as it writes and
reads data to and from files.
Socket address: The internet
address, port address and
address family of a socket. The
port and internet address
combination allows the network
to locate a socket.
Socket descriptor: An HP-UX
file descriptor accessed for
reading, writing or any
standard file system calls after
an Interprocess
Communication connection is
established. All Interprocess
Communication system calls
use socket descriptors as
arguments.
Stream socket: A socket that,
when connected to another
stream socket, passes data as a
byte stream (with no record
boundaries). Data is
guaranteed to arrive in the
Glossary
sequence sent. Stream sockets
use the TCP protocol.
TCP:
See Transmission Control
Protocol.
Telnet: A virtual terminal
protocol traditionally used on
ARPA networks that allows a
user to log into a remote host.
The telnet command uses the
Telnet protocol.
Transmission Control
Protocol: A protocol that
provides the underlying
communication support for
AF_INET stream sockets. TCP
is used to implement reliable,
sequenced, flow-controlled two-
way communication based on a
stream of bytes similar to pipes.
UDP:
See User Datagram
Protocol.
UNIX Domain Address: A
character string containing the
UNIX pathname to a UNIX
Domain socket.
UNIX Domain Protocol: A
protocol providing fast
communication between
