E-mail
The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the formation of the Internet. Today it is an important one to differentiate between Internet and internal e-mail systems. Internet e-mail may travel and even be stored unencrypted on many other machines and networks out of both the sender's and the recipient's control. It is also quite possible for the content to be read and even tampered with by third parties, if anyone considers it important enough during this period.
Purely internal or intranet mail systems, where the information never leaves the corporate or organization's network and servers, is much more protected, although in any organization there will be IT and other personnel whose job may involve monitoring, or at least occasionally accessing, the email of other employees are not been addressed to them. E-mail attachments have increased the usefulness of e-mail in a wide manner. When a file is attached to an email, a text representation of the attached data is actually appended to the e-mail text, later to be reconstituted into a 'file' on the recipient's machine for their use.
