Re: [LUG] multiprogramming

[Jon Lawrence <jon@xxxxxxxxxxxxxxx>]

Multiprogramming - Ain't never heard of it.
Multi-tasking - AFAIK, there is only one sort. Performing two ooperations 
simultaineously. Anything else is a fudge.
Single processing systems can do it. Take a look at the new Pentium IV xeons. 
They can use 4 way processing using just 2 processsors so long as the code 
doesn't try to access the same part of the chip at the same time - how god 
only knows.
