Answer
IPC or Inter Process Communication is a capability that allows one process to communicate with another process. The processes can be running on the same computer or on different computers connected through a network.
IPC enables one process to control or send information to another process, and for several processes to share the same information without interfering with one another.
Gordano’s products make use of IPC intensively to allow the status of one service to be communicated to another. For instance, when a message arrives in to SMTP that is destined for a local user, the SMTP service will send an IPC message to the IMAP service to inform it that a new message has just arrived for that user. The IMAP service can then make use of this IPC event to inform the user that new mail has just arrived for them.
