Define cloud computing.

• A. Storing data locally on a hard drive
• B. Delivering computing services over the internet
• C. A method of programming applications
• D. Using standalone software for tasks

Answer: (B)

Cloud computing is defined as delivering computing services over the internet. This includes a wide range of services such as processing power, storage, databases, networking, software, and analytics. By using the internet, users can access these resources without the need for local infrastructure or hardware, allowing for better scalability, flexibility, and sometimes cost-effectiveness.

This model enables individuals and companies to use computing resources on-demand. Rather than investing in physical servers or storage systems, users can simply connect to cloud services through web applications or software interfaces, using resources as they need them. This is particularly beneficial for businesses looking to reduce their IT expenditure and streamline operations, as they can easily scale their use of cloud services up or down based on current needs.

The other choices depict different methods of data management and software use, which do not encompass the full scope of what cloud computing offers. Storing data locally or using standalone software focuses on traditional computing methods that rely on physical infrastructure and do not leverage the advantages provided by cloud technology.
