SaaS stands for Software as a Service. It provides users with access to software applications over the internet, allowing them to use the software without downloading or installing it on personal devices. SaaS applications are typically hosted in the cloud, enabling users to access them from any location with an internet connection. This model offers flexibility, scalability, and cost-effectiveness, as it often operates on a subscription basis. Users can benefit from automatic updates, maintenance, and enhanced collaboration features when utilizing SaaS solutions.
