SaaS stands for which term?

• A. Security as a Service
• B. Software as a Service
• C. System as a Service
• D. Storage as a Service

Answer: (B)

Software as a Service is a cloud service model where the provider hosts software applications and makes them accessible to users over the internet. You don’t install or maintain the software on your own devices; you typically pay a subscription and access the application via a web browser or lightweight client. This is distinct from options like security-focused cloud services, cloud storage solutions, or other non-standard terms. Real-world examples include tools like Gmail, Google Docs, and Salesforce, which illustrate software delivered as a service rather than a product installed on individual machines.
