Encryption is the scrambling and coding of data, typically using mathematical
formulas called algorithms, before information is transmitted over any
communications link or network. A key is the specific code used by the
algorithm to encrypt or decrypt the data. Also see, Decryption and Key.
Electro-Static Discharge
Extended Service Set Identifier, defines the coverage area. Prior to the release of
the 802.11 specification the ESS_ID was called the Net_ID or Network
Identifier.
ESS_ID: 32 Alphanumeric characters, (case sensitive).
Flash memory is responsible for storing the system firmware and is non-volatile. If
the system power is interrupted the data will not be lost.
A computer that serves other terminals in a network, providing such services as
computation, database access, supervisory programs and network control.
International Electrotechnical Commission. This international agency regulates
laser safety by specifying various laser operation classes based on power
output during operation.
This is the lowest power IEC laser classification. Conformity is ensured through a
software restriction of 120 seconds of laser operation within any 1000 second
window and an automatic laser shutdown if the scanner's oscillating mirror
fails.
See MAC Address.
The space between two adjacent bar code characters in a discrete code.
A bar code in which characters are paired together, using bars to represent the first
character and the intervening spaces to represent the second.
A binary bar code symbology representing character pairs in groups of five bars
and five interleaved spaces. Interleaving provides for greater information
density. The location of wide elements (bar/spaces) within each group
determines which characters are encoded. This continuous code type uses no
intercharacter spaces. Only numeric (0 to 9) and START/STOP characters
may be encoded.
(Internet Protocol) The IP part of the TCP/IP communications protocol. IP
implements the network layer (layer 3) of the protocol, which contains a
network address and is used to route a message to a different network or
subnetwork. IP 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.
