About mail:

Mail is one of the most popular services available through the Internet. In the early days of the Internet, mail emerged as an inexpensive and efficient means of communications between researchers, scientists, people on high-tech jobs, and those in academia. The words inexpensive and efficient   are used here in relation to a telephone call; mail is a lot less expensive than a phone call and nearly as fast. And, like postal mail (snail mail or s-mail as it is sometimes called now); a message can easily be printed, to provide concrete documentation of the correspondence. Further more, from the user point of view, sending a 100-page document: both documents will typically have the same delivery time. There are some mail systems that cannot handle very large messages, in which case the user might have to find an alternative way of getting the information to intended recipient.

Today many people all over the world have been exposed to e-mail   they have either heard of it, used it occasionally, or felt they could not function without it E-mail began as a system in which an individual user could send a plain -text message via the internet to another user. E-mail has grown in many ways that no one predicted.


As in the early days of the telephone, the original   users of e-mail had a limited number of people with whom they could communicate. Now that e-mail is more prevalent, some of the advantages of using it are clear.


There is no trip to the post office and no need to search for stationary and stamps. Sending a memo or short note is easy. A message ca is informal or formal. E-mail makes publishing and discussing very easy.

Speed and inexpensive

E-mail is very fast, based on the speed of the underlying communication network. Once we are online, the cost of sending a message is relatively mall.


Despite of all the advantages, one should bear in mind that not every one everywhere has access to e-mail. Although the telephone is not truly universal either, it is still far out distances e-mail in terms of its worldwide ability.


With e-mail you are your own worst enemy. It is far more like that you will accidentally send e-mail to an unintended recipient than it is for someone actually to intercept your e-mail.


 It is possible, although unlikely, those eavesdroppers are “listening in” on e-mail correspondence. As a rule of thumb, never send an e-mail message that you would not want the whole world to see. It is simple for someone to pass on your message, called e-mail forwarding to another party.

3.Forgery and overload

 E-mail does not preclude forgeries, that it, someone impersonating the sender, since the sender is usually not authenticated in any way. And e-mail can also be too convenient and result in a flood of mail.
