(Dynamic Host Configuration Protocol) Software that automatically
assigns IP addresses to client stations logging onto a TCP/IP network.
Similar to BOOTP, but also permits the leasing of an IP address. It
eliminates having to manually assign permanent IP addresses. DHCP
software typically runs in servers and is also found in network devices
such as routers that allow multiple users access to the Internet.
A server in the network or a service within a server that assigns IP
addresses.
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
A binary bar code symbology representing each character by a group
of five bars, two of which are wide. The location of wide bars in the
group determines which character is encoded; spaces are
insignificant. Only numeric characters (0 to 9) and START/STOP
characters may be encoded.
European Article Number. This European/International version of the
UPC provides its own coding format and symbology standards.
Element dimensions are specified metrically. EAN is used primarily in
retail.
Generic term for a bar or space.
Total linear dimension occupied by all characters of a code pattern,
including start/stop characters and data.
ENQ software handshaking is also supported for the data sent to the
host.
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.
