Multiprocessing is a generic term for the use of two or more central processing units (CPUs) within a single computer system. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined (multiple cores on one die, multiple chips in one package, multiple packages in one system unit, etc.).
Multiprocessing sometimes refers to the execution of multiple concurrent software processes in a system as opposed to a single process at any one instant. However, the term multiprogramming is more appropriate to describe this concept, which is implemented mostly in software, whereas multiprocessing is more appropriate to describe the use of multiple hardware CPUs. A system can be both multiprocessing and multiprogramming, only one of the two, or neither of the two.

Ready for the iProd?
Fri, 16 May 2008 09:19:54 -0700
I felt certain this was an April Fool's joke, but apparently there's a real patent application behind it. (Picture from New Scientist.) Call it the iProd. The idea is you load it with answers to health-related questions, which the device uses to create a...
Yet another "iPhone killer:" Blackberry's Thunder (updated)
Fri, 16 May 2008 08:17:15 -0700
Did you hear that John Mayer is cheating on Apple again? That's right, Apple's poster boy blogged that he's using a Blackberry Bold. Not really surprising considering that RIM sponsored his 2007 tour. Note to Cupertino: send him a 3G iPhone, like, today. Although RIM hasn't said...

Back in the day when I had a Palm OS Treo I used to load up the custom ROMs created by Shadowmite since they took out a bunch of junk that was included by default and helped me recover some available memory. It seems he scored the first photos of...
