The Internet is a global network of interconnected computers, enabling users to share information along multiple channels. Typically, a computer that connects to the Internet can access information from a vast array of available serversand other computers by moving information from them to the computer's local memory.

The same Internet connection allows that computer to send information to servers on the network; that information is in turn accessed and potentially modified by a variety of other interconnected computers. A majority of widely accessible information on the Internet consists of inter-linked  hypertext documents and other resources of the World Wide web (WWW).

On the Internet computer users typically manage sent and received information with web browsers and other software for users' interface with computer networks includes specialized programs fo electronic mail, online chat, file transfer and file sharing.

Software as a Service vendors (SaaS Vendor) generally provide applications as a service over the Internet to be accessed using a web browser.  The Internet therefore allows users to access SaaS application software, without having to install software on their own computers, leading to reduced capital expenditure and operational cost savings.

The Internet also enables an Independent Software Vendor (ISV) to produce an application and market it on a world-wide basis, much sooner that used to be the the case.  SaaS vendors with a compelling offering and good execution can therefore experience explosive growth.

A SaaS Vendor is also able to use the Internet to monitor customer behaviour on-line and also to poll users on-line and make offers in order to refine the application and make improvements to the service quickly, in order to deliver even better customer service.
