Different ways to communicate online
Being able to send messages and talk to other people is an important part of modern life.
The internet has opened up lots of new ways for us to communicate.
At the touch of a button we have the ability to instantly get in touch with almost anyone, anywhere on the planet.
When did you last send an email? Millions of emails are sent every minute of the day. But what happens when you click on 'Send'? Believe it or not your email makes a pretty amazing journey.
First, the email software you are using communicates with an outgoing mail server. This is a special computer that manages email. Then the outgoing server looks up the address of the inbound mail server and sends the message there over the internet. The address of the inbound server is the bit after @ on an email address.
At the inbound server the mail is sent into the person's mailbox. The inbound mail server checks the bit before @ to see whose mailbox to send it to. When that person next connects to the server their mail will be passed to them.
