Which service model in cloud computing provides virtual machines, networks, and storage?

SaaS (Software as a Service) provides ready-to-use applications over the internet, abstracting away all underlying infrastructure.

IaaS provides the foundational infrastructure components such as virtual machines, virtual networks, and storage services, giving users control over operating systems and applications while the cloud provider manages the underlying physical infrastructure. This model offers the highest level of flexibility and management control over the infrastructure resources.

PaaS (Platform as a Service) provides a complete development and deployment environment, including runtime environments, but manages the underlying infrastructure.

DBaaS (Database as a Service) is a specialized offering that specifically manages database services, not general-purpose compute, network, and storage.
