What Does Multi-Processing Mean?
Multi-processing refers to the ability of a system to support more than one processor at the same time. Applications in a multi-processing system are broken to smaller routines that run independently. The operating system allocates these threads to the processors improving performance of the system.

In a symmetric multi-processing, a single OS instance controls two or more identical processors connected to a single shared main memory. Most of the multi-processing PC motherboards utilize symmetric multiprocessing.
