"SaaS" stands for Software as a Service in cloud computing. SaaS is a software distribution model that delivers applications over the internet, allowing users to access software on a subscription basis without installing or maintaining it locally. This model simplifies deployment, as updates and maintenance are handled by the service provider. SaaS applications are widely used for various purposes, such as email, customer relationship management (CRM), and collaboration tools. The key benefits of SaaS include cost-effectiveness, scalability, and ease of access from multiple devices and locations.
