What is VISP? Give one example to explain its use.

VISP stands for Virtual Internet Service Provider. It is a business model in which an Internet Service Provider (ISP) uses the infrastructure of another ISP to provide internet services to its customers.

For example, a small company wants to start an ISP business but doesn't have the resources to build its own infrastructure. They can become a VISP and use the infrastructure of a larger ISP to provide internet services to their customers. The larger ISP handles the technical aspects, while the VISP focuses on customer service and billing. This allows the smaller company to offer internet services without the need for a large initial investment.
