Final answer:
Personal SaaS refers to a subscription model for personal productivity software, which is cost effective and typically uses a pay-per-use or recurring payment system, but does not guarantee that data is stored on the user's personal computer.
Step-by-step explanation:
Which of the following is true of personal software-as-a-service (personal SaaS)? Personal SaaS typically refers to a subscription-based model where users pay for access to personal productivity software on a recurring basis, such as monthly or annually. One of the key advantages of this model is that it is cost effective because users can access high-quality, productivity software without the need for a significant upfront investment. Instead of purchasing software outright, personal SaaS involves paying for software on a pay-per-use basis or through a subscription, enabling access to the latest versions, features, and updates without additional costs. However, it does not necessarily ensure higher levels of security as not all data is stored directly on a user's personal computer; data may be stored on remote servers, and security is dependent on the service provider's measures and the user's internet safety practices.
