The acronym "SaaS" stands for Software as a Service, a cloud computing model that delivers software applications over the internet. In this model, users access applications via a web browser rather than installing them on local machines. SaaS providers manage the underlying infrastructure, application updates, and security, allowing organizations to reduce IT costs and streamline software deployment. The flexibility and scalability of SaaS solutions make them ideal for businesses seeking to enhance collaboration, improve access to applications from various devices, and efficiently manage resources.
