Distributed processing is the use of more than one processor, located in different
systems, to perform the processing for an individual task. Examples of distributed
processing in Oracle database systems appear in Figure10–1.

■ In Part A of the figure, the client and server are located on different computers,
and these computers are connected through a network. The server and clients of
an Oracle database system communicate through Oracle Net Services, Oracle’s
network interface.
■ In Part B of the figure, a single computer has more than one processor, and
different processors separate the execution of the client application from Oracle.
