Exa-Byte : 1 EB = 1024 PB
Zentta-Byte : 1 Zb = 1024 EB
Yotta-Byte : 1 YB = 1024 ZB

To avoid spam

Good ways to avoid spam are:

* Only give your email address to trusted friends.-
- Do not reveal your Email ID to unknown person
- Don’t publish your email address more widely than necessary. You can use a comments form on your web pages.

* Don’t open email messages that are from people you don’t know if you don’t know why the email was sent to you.

* If you do open a spam message, don’t reply to it, and don’t click on any links in it.
- if by mistake you open the spam message do not respond to it.

* Don’t ever buy anything from a spammer, the only reason spam exists is that it gets people to spread there network

* Most spam email comes with an invitation to ‘remove’ yourself from the list. Don’t believe it! These almost always bounce, and apparently might also be used to harvest new addresses.

* Use spam filters
