A packet assembler/disassembler, abbreviated PAD is a communications device which provides multiple asynchronous terminal connectivity to an X.25 (packet-switching) network or host computer. It collects data from a group of terminals and places the data into X.25 packets (assembly). A PAD also does the reverse, it takes data packets from packet-switching network or host computer and returns them into a character stream that can be sent to the terminals (disassembly). A FRAD (Frame Relay Assembler/Disassembler) is a similar device for accessing Frame Relay networks.

Famous quotes containing the word packet:
“we know our end
A packet of worm-seed, a garden of spent tissues.”
