What technology allows access to computing resources over a network?

Cloud computing represents a transformative technology that provides on-demand access to computing resources, such as servers, storage, and applications, through the internet. This model allows users to leverage powerful computing capabilities without the need for physical infrastructure on-site. By utilizing virtual resources hosted in data centers operated by a service provider, users can scale their computing needs up or down according to demand, which is both cost-effective and efficient.

Cloud computing encompasses various service models, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each offering different levels of control and management over the resources. This accessibility and flexibility fundamentally differentiate cloud computing from other options listed, as it specifically emphasizes the capability to obtain, manage, and use computing resources over a network dynamically.

The other choices refer to important technologies and concepts but do not directly encapsulate the broad and dynamic nature of accessing resources over a network. Virtualization is more about creating virtual versions of resources rather than providing access over a network. Data center management focuses on the administration of physical facilities and resources, and network storage pertains to storing data over a network rather than the on-demand access to computing power or resources. Thus, cloud computing is the most fitting
