Definition of Cloud Computing:

Cloud computing refers to the delivery of computing services (e.g., servers, storage, databases,

networking, software) over the internet.

A common feature of cloud computing is the "hosted" service model, where applications, storage, or

infrastructure are hosted and managed by a cloud service provider.

Explanation of Answer Choices:

A . Satellite-to-satellite: This involves communication between satellites, unrelated to cloud

computing.

B . Hosted: Correct. Hosted services are a fundamental aspect of cloud computing, where

applications or data are stored and accessed on remote servers.

C . Gateway transmission: Refers to communication gateways, unrelated to cloud computing

services.

D . Mainframe computing: Mainframes are large on-premises computers, not part of the cloud

model.
