How do we communicate

Over the internet

Emails

POP3

Definition: Post Office Protocol, version 3. The system that lets you retrieve and download your e-mails from a mail server over an Internet connection. The mail server will store any emails sent to you till you "log-on" and collect them.

WHO?

This would be good for people who don't rely upon or use their emails too often. Also they are for people who have small bandwidth or limited internet access and data. IMAP4 would use all this up.

WHY?

It does not push emails forward instead you have to go and 'collect' them. This means that they would not be good for people who would need important emails pushed onto their phone etc.

IMAP4

Short for Internet Message Access Protocol, a protocol for retrieving e-mail messages. The latest version, IMAP4, is similar to POP3 but supports some additional features. For example, with IMAP4, you can search through your e-mail messages for keywords while the messages are still on mail server. You can then choose which messages to download to your machine.

WHO?

It pushes emails onto you phone so would be ideal for those who need to instant message and have unlimited internet access.

WHY?

It tells you that you have mail as you get it so if there is something important you will know.
