How is SaaS delivered?

  1. Through direct installation

  2. Over the internet

  3. Via private networks

  4. On physical media

The correct answer is: Over the internet

SaaS (Software as a Service) is a cloud computing model where software applications are delivered over the internet as a service. Option A, direct installation, refers to the traditional method of installing software on a computer through a physical medium like a CD or USB. Option C, via private networks, may be used by organizations to create their own internal software delivery system, but it is not how SaaS is typically delivered. Option D, on physical media, is similar to option A and is not how SaaS is delivered. Therefore, the correct answer is B, as it is the only option that accurately describes the delivery method of SaaS.
