matched up with the IP address to turn part of the host ID address field into a field for subnets. Default is
often 255.255.255.0.
Substrate. A foundation material on which a substance or image is placed.
SVTP. Symbol Virtual Terminal Program.
Symbol. A scannable unit that encodes data within the conventions of a certain symbology, usually including
start/stop characters, quiet zones, data characters and check characters.
Symbol Aspect Ratio. The ratio of symbol height to symbol width.
Symbol Height. The distance between the outside edges of the quiet zones of the first row and the last row.
Symbol Length. Length of symbol measured from the beginning of the quiet zone (margin) adjacent to the start
character to the end of the quiet zone (margin) adjacent to a stop character.
Symbology. The structural rules and conventions for representing data within a particular bar code type (e.g.
UPC/EAN, Code 39, PDF417, etc.).

TCP/IP. (Transmission Control Protocol/Internet Protocol) A communications protocol used to internetwork
dissimilar systems. This standard is the protocol of the Internet and has become the global standard for
communications. TCP provides transport functions, which ensures that the total amount of bytes sent is
received correctly at the other end. UDP is an alternate transport that does not guarantee delivery. It is
widely used for real-time voice and video transmissions where erroneous packets are not retransmitted. IP
provides the routing mechanism. TCP/IP is a routable protocol, which means that all messages contain not
only the address of the destination station, but the address of a destination network. This allows TCP/IP
messages to be sent to multiple networks within an organization or around the world, hence its use in the
worldwide Internet. Every client and server in a TCP/IP network requires an IP address, which is either
permanently assigned or dynamically assigned at startup.
Telnet. A terminal emulation protocol commonly used on the Internet and TCP/IP-based networks. It allows a
user at a terminal or computer to log onto a remote device and run a program.
Terminate and Stay Resident (TSR). A program under DOS that ends its foreground execution to remain
resident in memory to service hardware/software interrupts, providing background operation. It remains in
memory and may provide services on behalf of other DOS programs.
Terminal Emulation. A "terminal emulation" emulates a character-based mainframe session on a remote
non-mainframe terminal, including all display features, commands and function keys. The MC909X Series
supports Terminal Emulations in 3270, 5250 and VT220.
TFTP. (Trivial File Transfer Protocol) A version of the TCP/IP FTP (File Transfer Protocol) protocol that has no
directory or password capability. It is the protocol used for upgrading firmware, downloading software and
remote booting of diskless devices.
TKIP. (Temporal Key Integrity Protocol) A wireless encryption protocol that periodically changes the encryption
key, making it harder to decode.
