3 definitions found From WordNet r 1.6 [wn]: handshaking n : grasping and shaking a person's hand (as to acknowledge an introduction or to agree on a contract) [syn: {handshake}, {shake}, {handclasp}] From Jargon File (4.2.3, 23 NOV 2000) [jargon]: handshaking n. [very common] Hardware or software activity designed to start or keep two machines or programs in synchronization as they {do protocol}. Often applied to human activity; thus a hacker might watch two people in conversation nodding their heads to indicate that they have heard each others' points and say "Oh, they're handshaking!". See also {protocol}. From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: handshaking 1. Predetermined hardware or software activity designed to establish or maintain two machines or programs in synchronisation. Handshaking often concerns the exchange of messages or {packet}s of data between two systems with limited {buffer}s. A simple handshaking {protocol} might only involve the receiver sending a message meaning "I received your last message and I am ready for you to send me another one." A more complex handshaking {protocol} might allow the sender to ask the receiver if he is ready to receive or for the receiver to reply with a negative acknowledgement meaning "I did not receive your last message correctly, please resend it" (e.g. if the data was corrupted en route). {Hardware handshaking} uses voltage levels or pulses on wires to carry the handshaking signals whereas {software handshaking} uses data units (e.g. {ASCII} characters) carried by some underlying communication medium. {Flow control} in bit-serial data transmission such as {EIA-232} may use either hardware or software handshaking. 2. The method used by two {modem}s to establish contact with each other and to agreee on {baud rate}, {error correction} and {compression} {protocol}s. 3. The exchange of predetermined signals between agents connected by a communications channel to assure each that it is connected to the other (and not to an imposter). This may also include the use of passwords and codes by an operator. [{Jargon File}] (1995-01-13)
