Neither Rain, Nor Sleet, Nor Dark of Night:
E-Mail
The United States Postal Service (USPS) promises to
consistently deliver mail, no matter what's going on with the weather. Although
e-mail services make no such promise, they have become equally as important. In
fact, I know a lot of people who get nervous when they can't get to their e-mail
for just a few minutes!
E-mail works a lot like paper mail with the postal service
(otherwise known as snail mail). You can
write a letter on paper and put it in an envelope. If you put a correct name and
address on the front of the envelope and put it in a mailbox, you can reasonably
expect the postal service to deliver the mail to the right place. If you put a
return address on the envelope, the recipient can reply by putting your address
on the front of the envelope.
For those of you who might not have used e-mail before, it
allows you to do basically the same thing, but without the paper. E-mail allows
you to type some text, identify to whom you want to send the text by putting
that person's e-mail address at the top of the e-mail, and send the e-mail. By
sending the e-mail, you do the equivalent of giving the e-mail to the postal
service. The service delivers the e-mail, and the next time your friend checks
his e-mail, he receives the message that you sent.
Each e-mail includes the text you typed, the recipient's e-mail
address, and your e-mail address. Because the recipient now knows your e-mail
address, he can easily respond to your e-mail. E-mail also enables you to send a
message to multiple recipients at once.
