Glossary of Terms
ARP
Address Resolution Protocol provides a way to retrieve the MAC address associated to an IP address.
Bandwidth
Describes the measure of data transfer capacity.
CAT5e Ethernet cable
Category 5e was designed for transmission speeds of up to 1 gigabit per second (Gigabit Ethernet).
CAT6 Ethernet cable
Same as Category 5e, except that it is made to a higher standard. Supports transmission speeds greater than
Gigabit Ethernet with less signal attenuation over a given length of cable.
CCD – Charge-Coupled Device
A type of image sensor converting light into electrical charges.
Contiguous Memory
A block of physical memory occupying consecutive addresses.
DHCP (Dynamic Host Configuration Protocol)
Protocol which provides a mechanism for allocating IP addresses dynamically by a DHCP server on a
network. Typically dedicated DHCP servers are a component of corporate networks. Used for managed
networks.
Driver
Also called a device driver, a program routine that links a peripheral device to the operating system. a
device driver is required for its frame grabber capabilities.
DSNU
Dark Signal Non-Uniformity (equivalent to FPN).
Ethernet Switch
A network device performing bridging at full wire-speed based on MAC addresses. Packet collisions are
eliminated when using a full duplex switch. An Ethernet Switch operates at Layer 2 of the seven-layer OSI
model.
FPN
Fixed Pattern Noise (equivalent to DSNU). FPN is the peak to peak difference between the minimum and
maximum measured values for all active valid pixels sensor in darkness. Fixed Pattern Noise does not
include a Random Noise component.
Frame
One complete image data set or its equivalent storage space.
Frame buffer
An area of memory used to hold a frame of image data. A frame buffer may exist on the acquisition
hardware or be allocated by the acquisition hardware device driver in host system memory.
GigE Vision specification
Specification of the Automated Imaging Association (AIA,
). Defines the
communication interface protocol used by any GigE Vision device.
