Final answer:
Resource pooling is an essential characteristic of the cloud model, enabling efficient resource allocation and scalability.
Step-by-step explanation:
Resource pooling is an essential characteristic of the cloud model. It refers to the ability of cloud providers to allocate and share computing resources, such as processing power and storage, among multiple users. This allows for efficient utilization of resources and scalability.
Asynchronous communication, distributed intelligence, and third normal form are not specifically related to the cloud model. Asynchronous communication refers to a type of communication where messages are sent and received with a time delay, while distributed intelligence refers to the distribution of computing intelligence across multiple devices or systems. Third normal form is a term used in database design to ensure data normalization.
