All different executing entities + such as processes, and ports communicate via asynchronous + signals. The most commonly used signal is a message.

If the receiver has terminated, the signal will + not arrive, but it is possible that it triggers another signal. + For example, a link signal sent to a non-existing process will + trigger an exit signal which will be sent back to where the link + signal originated from. When communicating over the distribution, + signals may be lost if the distribution channel goes down.</p> + <p>The only signal ordering guarantee given is the following. If + an entity sends multiple signals to the same destination entity, + the order will be preserved. That is, if <c>A</c> send + a signal <c>S1</c> to <c>B</c>, and later sends + the signal <c>S2</c> to <c>B</c>, <c>S1</c> is guaranteed not to + arrive after <c>S2</c>.</p> + </section> + <section> + <title>Synchronous Communication</title> + <p>Some communication is synchronous. If broken down into pieces, + a synchronous communication operation, consists of two asynchronous + signals. One request signal and one reply signal. An example of + such a synchronous communication is a call to <c>process_info/2</c> + when the first argument is not <c>self()</c>. The caller will send + an asynchronous signal requesting information, and will then + wait for the reply signal containing the requested information.
