The initial negotiation period immediately after a connection is established between two modems This is when the modems agree about how the data will be transmitted (e g , error correction, packet size, etc ) The set of rules they agree on is called the protocol
This is a method that allows computers or communications equipment to coordinate transmissions This is particularly important in higher speed communications
An exchange of predetermined signals between two computers or between a computer and a peripheral device such as a modem or a printer Handshaking allows the computer to ascertain whether another device is present and ready to transmit or receive data
Symptom of too much programming Most commonly seen among programmers who have just had their program erased by power fluctuations before they could save their program
A communications synchronizing technique carried out before and after any transfer of digital data It consists of a sequence of signals for non-clocked (asynchronous) systems in which a reply is needed to complete a data transfer operation
The process of two modems exchanging information via predetermined signals on how they will send data to one another, such as transmission speed, size of data packets, whether the operation will be full or half-duplex, etc This is done prior to Connect See also: negotiation
Is the way in which the data flow between computers/hardware is regulated and controlled Two distinct kinds of handshaking are described: Software Handshaking and Hardware Handshaking An important distinction between the kinds of signals of the interface is between data signals and control signals Data signals are simply the pins which actually transmit and receive the characters, while control signals are everything else
The initial modem-to-modem interchange that establishes the transmission mode and speed Handshaking produces the static-like noises that you hear when a data connection has been made
How two devices initiate communications For example, when your computer dials in to SBC Yahoo!, your modem and the modem at our POP send messages to each other--that's handshaking Back to Top
The process by which two devices initiate communications Handshaking begins when one device sends a message to another device indicating that it wants to establish a communications channel The two devices then send several messages back and forth that enable them to agree on a communications protocol
