Computer system having two or more processing units ('''''Multiple Processors''''') each sharing [[main memory]] and peripherals, in order to simultaneously process programs.<ref>http://www.yourdictionary.com/multiprocessor</ref><ref>http://www.thefreedictionary.com/multiprocessor</ref><ref>http://www.lexic.us/definition-of/multiprocessor#1</ref>
Sometimes the term '''''Multiprocessor''''' is confused with the term ''[[Multiprocessing]]''.
While ''Multiprocessing'' is a type of ''"processing"'' in which two or more processors work together to ''"process more than one program simultaneously"'', the term ''Multiprocessor'' is referred to the hardware architecture that allows ''multiprocessing''.<ref>http://www.yourdictionary.com/multiprocessor</ref><ref>http://www.blurtit.com/q307018.html</ref>
