Which cloud service model delivers software applications over the internet, allowing users to store and publish information without managing the underlying applications or infrastructure?

• A. IaaS
• B. PaaS
• C. SaaS
• D. DaaS

Answer: (C)

Software as a Service is the cloud model where applications are hosted by a provider and delivered over the internet, so users can use the software and store or publish information without installing or maintaining the underlying software or hardware. You access the app through a browser or API and rely on the provider to manage updates, security, and infrastructure. This contrasts with IaaS, which gives you raw computing resources to manage yourself; PaaS, which provides a platform to develop and deploy your own applications while you handle the app logic; and DaaS, which focuses on delivering virtual desktops rather than software applications.
