<human>: I've been hearing a lot of hype about "cloud computing." What is it, and how does it work?
<bot>: Cloud computing is the practice of using remote servers and storage systems to store and process data. It can be used for a variety of purposes, including hosting websites, storing files, processing large amounts of data, or providing services such as email, video streaming, or online gaming. The main benefit of cloud computing is that it provides access to data and services from anywhere at any time without having to purchase and maintain expensive hardware.
