Final answer:
A company licensing office software and email service through a browser is an example of SaaS (Software as a Service), where the service provider manages the applications and infrastructure.
Step-by-step explanation:
When a company licenses a service provider's office software and email service through a web browser, this is an example of SaaS (Software as a Service). SaaS provides applications over the internet, and users access these applications using a web browser. In this model, the cloud service provider manages the infrastructure and platforms that run the applications.
SaaS is distinct from IaaS (Infrastructure as a Service), where customers rent virtualized computing resources over the internet; PaaS (Platform as a Service), where customers rent hardware, operating systems, storage, and network capacity over the internet; and DaaS (Database as a Service), which is focused on providing a database platform.
