Computer Hardware Terms, Glossary and Dictionary

In the context of computers, handshaking indicates hardware or software to establish or maintain two machines or programs in synchronisation. Handshaking often requires the exchange of messages or packets of data between two systems. Hardware handshaking signals between two computers which are carried by voltage levels or pulses on wires. There are many handshaking protocols for software handshaking. Basically, the handshaking protocol send a "hello" message to the receiving system and get a "ok" responce. When the communication between the two systems finished, a "finish" message should be send and confirmed by both systems.
