Definition of Software as a Service (SaaS)
Software as a Service (SaaS) is a software licensing model where the software is hosted on external servers and accessed through the internet, typically via a web browser. Users pay a subscription fee to use the software, eliminating the need for installation on local machines and enabling easy access from various devices.
