Internet protocols transfer information between computers, but cannot store it. Internet protocols are only capable of transferring information between computers. For example, the SMTP protocol (simple mail transfer protocol), which is used in email communication, enables a near real-time and worldwide communication. The problems is that the SMTP protocol (and other Internet protocols) cannot store the messages sent through it. If the recipient of an email message does not write down the message (content, delivery time, relation to other prior messages, etc.), the message disappears into cyberspace. The user experience is very limited, even if the potential is significant.
