address - DHCP

A address

A string uniquely identifying a particular interface or a device on that

interface 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).

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.

DHCP

Short for Dynamic Host Configuration Protocol, a protocol for assigning

dynamic IP addresses to devices on a network. With dynamic

addressing, a device can have a different IP address every time it

connects to the network.

In some systems, the device's IP address can even change while it is still

connected. DHCP also supports a mix of static and dynamic IP

addresses.
