STP (Shielded Twisted Pair) - Telephone wire that is wrapped in a metal sheath
to eliminate external interference.
Subnet Mask - The method used for splitting IP networks into a series of sub-
groups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the Internet Protocol (Internet Protocol) to send data in the form of message
units between computers over the Internet. While IP takes care of handling the
actual delivery of the data, TCP takes care of keeping track of the individual
units of data (called packet) that a message is divided into for efficient routing
through the Internet.
TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the
basic communication language or protocol of the Internet. It can also be used
as a communications protocol in a private network (either an intranet or an
extranet). When you are set up with direct access to the Internet, your comput-
er is provided with a copy of the TCP/IP program just as every other computer
that you may send messages to or get information from also has a copy of
TCP/IP.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol
that has no directory or password capability.
Throughput - The amount of data moved successfully from one place to
another in a given time period.
TX Rate - Transmission Rate.
UDP (User Datagram Protocol) - A communications method (protocol) that
offers a limited amount of service when messages are exchanged between com-
puters in a network that uses the Internet Protocol (IP). UDP is an alternative
to the Transmission Control Protocol (TCP) and, together with IP, is sometimes
referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the
Internet Protocol to actually get a data unit (called a datagram) from one com-
puter to another. Unlike TCP, however, UDP does not provide the service of
dividing a message into packets (datagrams) and reassembling it at the other
end. Specifically, UDP doesn't provide sequencing of the packets that the data
arrives in. This means that the application program that uses UDP must be able
to make sure that the entire message has arrived and is in the right order.
PCI (Peripheral Component Interconnect) - A peripheral bus commonly used
in PCs, Macintoshes and workstations. It was designed primarily by Intel and
first appeared on PCs in late 1993. PCI provides a high-speed data path
between the CPU and peripheral devices (video, disk, network, etc.). There are
typically three or four PCI slots on the motherboard. In a Pentium PC, there is
generally a mix of PCI and ISA slots or PCI and EISA slots. Early on, the PCI
bus was known as a "local bus."
PCI provides "plug and play" capability, automatically configuring the PCI
cards at startup. When PCI is used with the ISA bus, the only thing that is gen-
erally required is to indicate in the CMOS memory which IRQs are already in
use by ISA cards. PCI takes care of the rest.
PCI allows IRQs to be shared, which helps to solve the problem of limited IRQs
available on a PC. For example, if there were only one IRQ left over after ISA
devices were given their required IRQs, all PCI devices could share it. In a PCI-
only machine, there cannot be insufficient IRQs, as all can be shared.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal com-
puter are external sockets for plugging in communications lines, modems and
printers.
PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL
providers for connecting personal computers to a broadband modem for
Internet access. It is similar to how a dial-up connection works but at higher
speeds and quicker access.
RJ-11 (Registered Jack-11) - A telephone connector that holds up to six wires.
The RJ-11 the common connector used to plug a telephone into a wall.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Static IP Address - A permanent IP address that is assigned to a node in an IP
or a TCP/IP network.
Static Routing - Forwarding data in a network via a fixed path. Static routing
cannot adjust to changing line conditions as can dynamic routing.
Storage - The semi-permanent or permanent holding place for digital data.
