  • 3. The e-mail process E-mail stands for electronic mail. To send and receive e-mail, you need an e-mail account. E-mail accounts can be set up through software providers, such as Hotmail, Yahoo and Google mail. The e-mail addresses of the people you know can be stored as contacts in your address book. The process of sending e-mail is similar to the traditional letter, but it is all done electronically, via the Internet. 3 of 10 © Boardworks Ltd 2007

  • 10. Stuck on you All e-mails are text files. Other types of files can be forwarded as an attachment to an e-mail. The symbol for an attachment is a paper clip. Look at the size of the attached files. Big files take longer to send. Some e-mail inboxes don’t allow big attachments as they take up a lot of storage space. E-mails and attachments can be saved and/or deleted just like any other files. 10 of 10 © Boardworks Ltd 2007

  • 13. Problems with e-mail Spam is the e-mail equivalent of junk mail. It is often sent by companies trying to sell their products to people who haven’t asked for information about them. Spam takes up a lot of Internet bandwidth and it can be annoying for people to have to wade through lots of messages they don’t want to find the ones they do. Many countries are trying to make it illegal to send spam. 13 of 10 © Boardworks Ltd 2007
  • 14. Phishing and fraud E-mails are sometimes used by criminals to steal money. They send e-mails to thousands of people in the hope that a few will fall for their trick. Phishing e-mails pretend to be from banks. They ask the customer to enter their bank details because of some problem. They then use these details to steal money. Other frauds pretend to give away free gifts or prizes. Another common fraud is to pretend to need help to get lots of money out of another country. They just need a bank account to pay it into… The websites that fraudsters set up are usually closed after a few days, which makes them difficult to trace. 14 of 10 © Boardworks Ltd 2007
  • 15. Other problems with e-mail A virus is a piece of code which can sometimes damage the files on your computer. It is possible to pass a virus on through e-mail. It is best not to open an e-mail unless you know where it has come from, especially if it has attachments. You should always virus check e-mails, even from people you do know. 15 of 10 © Boardworks Ltd 2007
  • 16. E-mail or snail mail? 16 of 10 © Boardworks Ltd 2007
  • 17. Encryption Encryption means using a system to translate data into a secret code. To access an encrypted file, the recipient will need to have a special secret key or password which will decrypt the file. Encryption is the most effective way to ensure that data sent by e-mail is secure. However, governments worry about encryption because it makes it difficult for them to check e-mails, even when national security is involved. 17 of 10 © Boardworks Ltd 2007
