In cloud computing, which service model delivers software applications to a client over the Internet or a local area network?

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

Answer: (B)

Software as a service delivers fully functional software applications hosted by a provider and accessed over the Internet or a local area network. Users interact with the software via a web browser or thin client, while the provider handles hosting, updates, security, and maintenance. This means you don’t install or manage the application on your own devices, and you can scale usage as needed. This differs from other cloud models: infrastructure as a service provides raw computing resources (VMs, storage) rather than applications; platform as a service offers an environment to develop and deploy apps; and desktop as a service focuses on delivering virtual desktops rather than standard software apps. So, the described service model is software as a service.
