From Second Part of RDBMS Discussion ARL Database Tutorial -- February 98. by Gang Cheng Marek Podgorny Chao-Wei Ou
Every time the Oracle 7 Server is started, the System Global Area (SGA) is allocated and the Oracle 7 Server background processes are started. The combination of memory buffers and background processes is called an Oracle Server Instance.
The SGA is a group of shared memory buffers allocated by the Oracle 7 Server for an instance
The background processes asynchronously perform distinct tasks on behalf of all database users of the instance
