TCP/IP
A 32-bit number used to separate the network and host
sections of an IP address. A custom subnet mask subdivides
an IP network into smaller subsections. 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.
Default is often 255.255.255.0.
A foundation material on which a substance or image is
placed.
Symbol Virtual Terminal Program.
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.
The ratio of symbol height to symbol width.
The distance between the outside edges of the quiet zones
of the first row and the last row.
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.
The structural rules and conventions for representing data
within a particular bar code type (e.g. UPC/EAN, Code 39,
PDF417, etc.).
(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.
