2. What is ?
stands for ‘electronic mail’. Its is used for digitally sending messages (whether it only has an attachment or a photo in it) via the Internet to another user. Just like the real postal service, an address is required in order to send mail to the right person, this is called an ‘ address’.
It is then stored using a system called ‘store and forward’ and then sent to the user when they next come online.
It has been used since 1993 and has revolutionised communication via the Internet over long distances.

3. How do you store other peoples addresses?
Simple, its just like how you store phone numbers. In a phone book! Except with you use an address book and you store peoples address instead. This allows the user to not have to remember a lot of s in order to send a message to many different people.

4. Benefits Of
s are delivered extremely fast when compared to traditional post.
s can be sent 24 hours a day, 365 days a year.
Webmail means s can be sent and received from any computer, anywhere in the world, that has an Internet connection.
Cheap - when using broadband, each sent is effectively free. Dial-up users are charged at local call rates but it only takes a few seconds (for conventional , eg text only) to send an .
s can be sent to one person or several people.

5. Disadvantages Of E-Mail
The recipient needs access to the Internet to receive .
Viruses are easily spread via attachments (most providers scan s for viruses on your behalf).
Phishing - sending an to a user falsely claiming to be a legitimate company to scam the user into providing information, such as personal information and bank account numbers on a bogus website. The details will then be used for identity theft.

6. Protocols
Simple Mail Transfer Protocol SMTP The internet standard used for sending messages across IP networks in server-to-server transfers. Also used by users to send a message to an server.
Post Office Protocol 3 POP Used to retrieve s from an server over a TCP/IP connection. This is the most widely used retrieval protocol. Normally users download s to their local computer using POP3 - this deletes them from the server Internet Message Access Protocol
IMAP
This is the other popular retrieval protocol. Normally users work on the s as they reside on the server using IMAP and do not download them.

7. Carbon Copy (Cc)
A carbon copy (Cc) is an exact copy of an or anything on that matter. It can be used to send the same message to multiple recipients.

8. Blind Carbon Copy (Bcc)
A Blind Carbon Copy (Bcc) is similar to a Carbon Copy (Cc) but it doesn’t show the recipients if the message has been sent to anyone else if their address is placed into the ‘Bcc’ section.
