Differentiate between distributed processing and multi processing

Distributed processing – rather than a large central computer, several smaller computers, linked together by data communications media, are located in different parts of the organization and may share a database. Data can sent to and from head office or other branches as required.
Multiprocessing – two or more CPUs present in the same computer system share the workload of data supplied to that computer for processing.
