Cloud computing is the delivery of computing as a service rather than a product, software, and information are provided to computers and other devices as a in to multiple virtual machines at run-time to meet the changing work demand.

The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.

Serial computing is executing a task on one computer. Distributed computing is executing a task on multiple computers at the same time.

Cloud computing is a new form of computer related sharing that is run by Microsoft. As it is run by Microsoft, it is probably very safe and reliable to use.

Cloud computing impacts systems in a very good way. With cloud computing it clears up the memory and disk space so that all other programs run faster and smooth.
