Email and the world wide web are simply examples of the types of file which can be sent between computers. The effectiveness of email as a communications tool, the development of the web, with it's graphical presentation, and of the tool to view and access this information, Mosaic, were instrumental in advancing the popularity of the Internet. Mosaic was the first example of a web browser and has been developed for a wide range of computing platforms. To send and receive emails and to publish information on the Internet, however, requires a permanent connection. Its members all operate their own International links to the global Internet, and a majority of them provide access services to UK customers.
Email is probably the most useful example of the transfer of files between computers.
Flexible - An email is like a fax, a personal letter or a memo, depending on its use, and can include pictures or any other file as an attachment. For example, it can be a great way to distribute newsletters or communicate with staff internally. Fast - Email messages will arrive at their destination within a few minutes and usually a few seconds. On reading a message, a simple click is all that's needed to reply, forward, copy, print, delete or file the received message for future reference, all without handling or creating any paper. Email software presents the user with a list of incoming messages, showing the subject of each message and the identity of the sender and usually has an email address book.
