What is a benefit of using cloud computing in networking?

End users have the freedom to use personal tools to access information and communicate across a business network.

Technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated.

Network capabilities are extended without requiring investment in new infrastructure, personnel, or software.

Home networking uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables.
