And, particularly the old protocols, are actually text-based conversations that a human could simulate. Meaning, I can actually connect with any internet server, even without an e-mail program, and open a conversation that results in an e-mail being delivered there. That e-mail delivery protocol is called SMTP. It is pretty much as simple as that I say HELLO and the other server acknowledges it. And I say "I've got mail from ffunch@worldtrans.org" and it says ok. And I say "I've got mail for joe@blow.com" and it says ok, if it wants to receive it. And then it asks me to send the message, and then I tell it I'm done, and it says thank you for the message. Those are not the actual commands, but it isn't far off. There is another protocol, called POP3 for picking up messages from one's mailbox on a server. It is relatively simple too. Nowadays things might be called e-mail even if it doesn't use those protocols. For example, if two people at hotmail write to each other, it doesn't have to go through those protocols at all, because everything is on the server. And one doesn't actually pick up one's mail, as it all stays on the server, so POP isn't being used. But a basic characteristic of e-mail is that it is a "push" technology. I.e. the sender decides when and what to send. And that is in part what makes it stop working for people, in that you might be overloaded, and you might get stuff you don't want. A webpage is a "pull" technology. You decide what you want to go and look at and when. That we can better control, and there's little likelyhood of being overloaded. 10 Dec 2001 @ 14:51 by ming : email programs Any e-mail program will do fundamentally the same thing, and an open source or free e-mail program does the basic things just as well usually. For example, you can use Eudora, which has a free version, and which is excellent. It does need a connection with the Internet while it is checking mail and sending it, though. But if one uses something like hotmail or yahoo mail, one can pick it up from any webbrowser, so one doesn't necessarily need one's own connection, if one can get access to a computer anywhere. 30 May 2007 @ 17:46 by meisam @194.225.76.99 : i dont khnow? my work is not underestand the secret of rose flower Other entries in Internet 25 Oct 2007 @ 21:47: Static or dynamic web metaphors 28 Mar 2007 @ 05:36: The Tyee - Vancouver's Online Newspaper 11 Jul 2006 @ 15:12: Response to Josep L.I.
