Dropbox and Yahoo Mail are examples of what type of cloud service?

Dropbox and Yahoo Mail are examples of Software as a Service (SaaS) because they provide software applications that are hosted in the cloud and accessible via the internet. Users can utilize these applications without needing to install software on their local devices, allowing for easier access and updates. This model provides a subscription-based service where users can share files, collaborate on documents, or manage emails from any location using an internet connection.

In contrast, other cloud service models like Platform as a Service (PaaS) are designed for developers to build applications without managing the underlying infrastructure, and Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. Function as a Service (FaaS) refers to a serverless computing model that allows users to run code in response to events without managing servers. Thus, these models cater to different needs, highlighting why Dropbox and Yahoo Mail fit squarely within the SaaS category.
