In the beginning, a program, called ?client software,? was necessary to handling the mail. There are many different email applications available, some of which cost money to use while others are free; some Internet providers even include it with the service. Client software is still used today, but there is another more flexible method that has become more popular in recent times.
Webmail
In addition to accessing electronic mail through client software, webmail is another popular option. Most service providers offer this as an additional benefit, where the user can access his or her mailbox over the Internet, from any computer or other web-connected device. Some email services are specifically designed for using the World Wide Web as their primary interface. These sites, called ?portals,? have become very popular, as they usually offer individuals a chance to open an email account at no charge, along with access to a search engine, news, calendar, and many other resources from a single spot.
History
Though there is some degree of uncertainty as to when email was invented, the father of the modern version is generally regarded to be an American, Ray Tomlinson. Before Tomlinson, users could send messages to each other, but only when they were connected to the same computer. Even once computers were networked, messages could not be targeted to a particular individual. Tomlinson devised a way to address mail to certain users, and thus was credited for one of the most important communication inventions in the 20th century.
Tomlinson?s idea was to identify the name of the user and the computer at which he or she was located. As a result, the basic formula for addressing an email was username@usercomputer. This standard has not changed much over the years, other than the user computer is now commonly replaced by the name of a service provider.
