What term refers to a computing model where server software operates on dedicated computers?

The term that best describes a computing model where server software operates on dedicated computers is Client/Server. In this model, the server is a powerful machine that provides resources or services to multiple client devices over a network. Client machines, which can be personal computers or other devices, connect to the server to request and use those resources.

This setup allows for a centralized management of resources and services, as the dedicated servers handle requests efficiently, often leading to better performance and scalability. The Client/Server architecture is foundational for many computing environments, especially in enterprise settings where applications require the centralization of information and services for better security and access control.

In contrast, other options describe different models. Peer-to-Peer refers to a decentralized approach where each participant can act as both a client and a server. Hybrid Cloud combines on-premises infrastructure with cloud services rather than relying solely on dedicated servers. Distributed Computing involves a network of interconnected computers that work together, often leading to resource sharing but not strictly operating on dedicated machines like in the Client/Server model.
