"Cloud computing" (Cloud Computing) is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grid Computing), or the business implementation of these computer science concepts. Many companies in the multinational information technology industry, such as IBM, Yahoo and Google, are using cloud computing to sell their products and services.
The term cloud computing may be borrowed from the "electronic cloud" in

go through any point between point A and point B. Such "motion" or "transition" is against our daily experience. However, those who have some knowledge about quantum physics will immediately point out that quantum (such as electronics) jumps on different levels of energy in an instant and has such a kind of transition behavior. Therefore, this kind of movement does not exist in nature, but we cannot observ
