Differences between parallel computing, distributed computing, and cloud computing

Parallel computing is a computer equipped with a multi-processor. contract-based collaborative computing is performed between multiple processors, and the final result is processed by one computer.

Distributed computing is a network-connected computer with its own host and processor. It allocates shared computing tasks and computing information over the network.

Cloud computing refers to the computer that sends computing commands to the server over the network, so that the server executes computing tasks and returns the results to the computer that sends the commands.

For computer users, parallel computing is done by a single user, distributed computing is done by multiple users, and cloud computing is not performed by users,
It is handed over to the server at the other end of the network.
