Which of the following defines Software as a Service (SaaS)?

• A. A one-time purchase of software
• B. A subscription model where software is licensed
• C. A type of antivirus software
• D. An operating system

Answer: (B)

The definition of Software as a Service (SaaS) is best described as a subscription model where software is licensed. This model allows users to access software applications over the internet, typically on a subscription basis, rather than purchasing and installing the software on individual devices. With SaaS, the software is hosted in the cloud, which provides benefits such as automatic updates, scalability, and accessibility from any device with internet access. This approach contrasts with a one-time purchase of software, where users buy a license for a specific version that they install and maintain on their systems. Additionally, SaaS is not specific to antivirus software, which pertains to a different category of applications designed to protect against malware. Lastly, SaaS is distinct from operating systems, which are foundational software that manage computer hardware and software resources. Understanding these distinctions highlights why the subscription model captures the essence of SaaS.
