You don't really have much of an understanding about computers, operating systems, and the things done inside the OS. If you want an understanding of what multi-tasking really is, do a search on operating system schedulers. You're talking about multi-processing, not multi-tasking. And operating systems, like VMS, Unix, and Linux, have been doing both for years. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
