Introduction to Online Services
The level of internet technology available today has given rise to many online services such as shopping online and people being able to control their personal finances online. Whereas, when the internet was first invented none of these services were actually available, and it was not even possible to check your e-mail online, which is now seen as an extremely basic task in comparison with what we are able to do with the technology available today.
Communications
Email (Electronic Communication) commonly is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and-forward model in which email servers accept, forward, deliver and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to an email server, for as long as it takes to send or receive messages. [1]
Gmail

Gmail was launched as an invitation-only beta release on April 1, 2004 and it became available to the general public on February 7, 2007, though still in beta status at that time. The service was upgraded from beta status on July 7, 2009, along with the rest of the Google Apps suite. [2]

Individual Gmail messages, including attachments, may be up to 25 MB, which is larger than many other mail services
