accepts “packets” from the layer 4 transport protocol (TCP or UDP), adds its own header to it and delivers a “datagram” 
to the layer 2 data link protocol. It may also break the packet into fragments to support the maximum transmission unit 
(MTU) of the network.

station must have a unique IP address. A 32-bit address used by a computer on a IP network. Client workstations have

T
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.
Terminal. See Mobile Computer.
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 VC5000 Series supports Terminal Emulations 
in 3270, 5250 and VT220.
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.
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.
Tolerance. Allowable deviation from the nominal bar or space width.
Transmission Control Protocol/Internet Protocol. See TCP/IP.
Trivial File Transfer Protocol. See TFTP.
TSR. See Terminate and Stay Resident.
U
UDP. User Datagram Protocol. A protocol within the IP protocol suite that is used in place of TCP when a reliable delivery 
is not required. For example, UDP is used for real-time audio and video traffic where lost packets are simply ignored, 
because there is no time to retransmit. If UDP is used and a reliable delivery is required, packet sequence checking and 
error notification must be written into the applications.
UPC. Universal Product Code. A relatively complex numeric symbology. Each character consists of two bars and two 
spaces, each of which is any of four widths. The standard symbology for retail food packages in the United States.

memory is lost.
