Email: It's Just like Mail

Rule number 1: The system behind email essentially just replicates the system behind regular mail. You might think email is a called that because the result is like that of traditional mail. Just like how an online shopping cart behaves like a regular shopping cart but the system behind it is much more complex than simply putting something in a rolling basket. The modern mail system is just as complex as that of electronic mail. Both email and mail start off by addressing who the message is supposed to reach, then the message is put in either a mail box or sent to your personal router. After that the message is picked up by the mail man (or the system of connections known as the internet) and brought to a mail office (or DNS server). The mail office then figures out where the message is supposed to go, according to the address. The mail office then decide which route would get the message to the recipient the fastest (Either through physical travel or through the system of connections). Once it gets to this other destination close to the recipient, the message gets delivered to the mailbox/ router. From there it is (hopefully) given to the specific person it was intended for. Unlike regular mail that has people who can interpret human intentions, if you mess up an email address it will not be sent to the right place or it will not be sent at all. Luckily email has the advantage of getting immediate feedback if these errors occur. With traditional mail it will take a long time to find out that a message was not sent, and sometimes you will never find out that there was an error.
