In Layman’s Terms
Software as a Service (SaaS) is a way of delivering software over the internet. Instead of installing and maintaining software on your computer, you access it through a web browser. This is like using Google Docs instead of installing Microsoft Word.
In Technical Terms
SaaS is a cloud computing service model that provides users with access to software applications hosted by a service provider. These applications are delivered over the internet and accessed via web browsers or APIs. The service provider manages the infrastructure, security, and updates.
