What defines a standalone computer?

A standalone computer is characterized by its ability to function independently without being connected to a network. This means that all necessary software and data are stored locally on the device, allowing users to perform tasks without access to external resources or services typically accessed through a network.

Option C accurately describes this concept, as it specifies that the computer is not connected to any network, emphasizing its independence. A standalone computer can still connect to devices like printers or external drives, but its key defining feature is lack of reliance on a network for functionality.

While other options may describe common scenarios for computers, none convey the essential quality of being a standalone machine. For example, a personal computer connected to a network would not be considered standalone, while one without internet access could still be part of a local network—that does not align with the definition of a standalone computer. Thus, option C clearly encapsulates the meaning of a standalone computer.
