Software as a Service (SaaS) is a software distribution model where applications are hosted by a service provider and made accessible to users over the internet. In simple terms, instead of purchasing and installing software on individual computers or servers, users can access and use software applications through a web browser. This approach eliminates the need for users to handle installation, maintenance, and updates, as everything is managed by the service provider. SaaS has gained significant popularity due to its convenience, scalability, and cost-effectiveness.
