What is cloud computing?

• A. A software program that operates offline
• B. The delivery of services over the internet
• C. An internal network for data storage
• D. An IT solution for local servers

Answer: (B)

Cloud computing refers to the delivery of a variety of services over the internet, enabling users to access and utilize computing resources without the need for local infrastructure or hardware. This model allows individuals and organizations to use applications, process data, store information, and manage resources remotely through the internet, rather than relying on on-premises systems.

The primary benefit of cloud computing lies in its scalability, flexibility, and cost-effectiveness. Users can quickly scale up or down depending on their needs, accessing a wide range of services such as storage, processing power, and applications on an as-needed basis. This characteristic contrasts sharply with traditional computing environments that require substantial investment and maintenance of physical hardware and infrastructure.

In this context, cloud computing facilitates the efficient use of extensive computing capabilities while reducing the burden of maintenance and management, which aligns perfectly with the definition provided in the correct choice.
