Final answer:
The most suitable network model for the University of Kingston to create a private area network for data exchange is a Campus Area Network (CAN), which is designed to cover the area and user volume of a university campus.
Step-by-step explanation:
The best-suited network model for a university campus looking to create a private network for data exchange among students and teachers from various departments would be a Campus Area Network (CAN). This network model provides the required coverage for larger areas such as university campuses and can handle a significant number of users simultaneously. A WAN (Wide Area Network) is more extensive, covering cities, states, or even countries, which exceeds the needs of a single campus. A PAN (Personal Area Network) typically covers a very small area around a person and is too limited for this use, and a BAN (Body Area Network) is even more specialized, focusing on wearable devices on a person's body.
Given these options, a CAN is the optimal choice for the University of Kingston. It will facilitate robust and efficient connectivity tailored to a university's spatial and functional requirements, enabling fast and secure communication between departments and the various amenities available on campus.
