ARP Address Resolution Protocol. ARP is a TCP/IP protocol that is used to get the physical address of a client

node or server. The system that sends the ARP request broadcasts the IP address of the system it is

attempting to communicate with. The request is processed by all nodes on the subnet and the target node

returns its physical address to the sending node.

default A value or parameter that is automatically set by an application or process when an alternate is not

provided by means external to that application or process.

distribution media The media that is used to make software kits available for installation. The HP SFS system software is

typically distributed on CD-ROM.
