subsystem
subsystem. The software and/or hardware facilities that provide users with access to a set
of communications services.
Transmission Control Protocol (TCP). The Internet standard transport-level protocol that
provides the reliable, full-duplex stream service on which many application protocols
depend. TCP allows a process on one machine to send a stream of data to a process
on another. It is connection-oriented, in the sense that before transmitting data
participants must establish a connection. Software implementing TCP usually resides
on the operating system and uses the Internet Protocol (IP) to transmit information
across the Internet. It is possible to terminate (shut down) one direction of flow across
a TCP connection, leaving a one-way (simplex) connection. The Internet protocol suite
is often referred to as TCP/IP because TCP is one of the two most fundamental
protocols.
TELNET. The Internet standard protocol for remote terminal connection service. TELNET
allows a user at one site to interact with remote timesharing systems at another site
just as if the user’s terminal is connected directly to the remote machine. That is, the
user invokes a TELNET application program that connects to a remote machine,
prompts for a login ID and password, and then passes keystrokes from the user’s
terminal to the remote machine and displays output from the remote machine on the
user’s terminal.
TLD. See Top-Level Domain (TLD)
Top-Level Domain (TLD). Refers to the suffix attached to Internet domain names. There
are a limited number of predefined suffixes, and each one represent a top-level
domain. Current top-level domains include:
•
com – Commercial businesses; this is the most common TLD
•
gov – U.S. government agencies
•
edu – Educational institutions, such as universities
•
org – Organizations (mostly nonprofit)
•
mil – Military
•
net – Network organizations
Unicode. The 16-bit character encoding used by Java for the char and java.lang.String data
types.
URL. Uniform Resource Locator.
wait mode. In the NonStop Kernel operating system, the mode in which the called
procedure waits for the completion of an input/output (I/O) operation before returning a
condition code to the caller. Compare nowait mode.
Web Container. a Java runtime environment that manages the lifecycle of servlets and
JSP.
