	An '''IMP interface''' is a [[device controller]] used on a [[host]] (i.e. on its [[bus]]) to attach them to systems which used the special [[1822 interface\|1822 communication interface]] (defined in [[Bolt, Beranek, and Newman\|BBN]] Report No. 1822); these included initially the [[Interface Message Processor\|IMPs]] of the [[ARPANET]] (hence the name), and later the PRUs of the [[Packet Radio Network‎]].
