interface which is interpreted at the E5810 LAN/GPIB Gateway to identify
the interface or device.

B bridge
In telecommunication networks, a bridge is a product that connects a
local area network (LAN) to another local area network that uses the
same protocol (for example, Ethernet or token ring). You can envision a
bridge as being a device that decides whether a message from you to
someone else is going to the local area network in your building or to
someone on the local area network in the building across the street. A
bridge examines each message on a LAN, “passing” those known to be
within the same LAN, and forwarding those known to be on the other
interconnected LAN (or LANs).
C client
Part of the client/server model used in distributed computing. A client is a
computer system that requests services from a server computer system,
such as I/O application requests, networking requests, etc.
controller
A computer used to communicate with a remote device such as an
instrument. In the communications between the controller and the device,
the controller is in charge of and controls the flow of communication that
is, it does the addressing and/or other bus management). The controller
acts as the remote I/O client to the E5810 server.
D device
A unit that receives commands from a controller. Typically a device is an
instrument but could also be a computer acting in a non-controller role, or
another peripheral such as a printer or plotter.
