E-Mail Systems

E-mail is an online communication tool that has become an important key to all businesses, vendors, schools, and families.  E-mail has become the new way to conversate. At first it was the hip new way to write a letter, but now it has taken over a big part of the way we talk. The number of emails sent each daily is equal to the number of letters mailed each day.  E-mail provides a quick delivery, low cost, accessible, convenient, and manageble way to say what needs to be said. 

There are two components to an e-mail address.  There is an user ID and a host name.  Included in the host name is a TLD, or top-level domain like ".edu" or the popular, ".com" E-mail messages are sent from server to server over the web until it reaches its receipient's inbox. 

There are several e-mail clients that create, send and receive e-mails.  These clients provided many services to help people get their messages to their recipients.  E-mail servers and protocols help in the delivery of emails.
