Is it like extreme programming?

Extreme programming is basically where you toss two people in front of a computer and say "code!"

Then you shoot one of them in the head and the blood splatters all over the monitor. Then you push his body aside and tell the other developer to get in the other computers chair. (So while he codes he will have to code through the layer of blood on the monitor so that he keeps in mind that could happen to him if he doesn't do a good job.)

The term ``multiprogramming'' can be considered equivalent to ``multitasking''. Thus, it describes the ability to run multiple processes at the ``same'' time. On a uni-processor it's really only one process that executes at time, and it will be stopped when a clock interrupt occurs (this happens many times per second, depends on the system). Then the operating system's interrupt handler is called, which will update the time and check the callout-queue for expired timers and post signals, if necessary. If a process has used up all CPU time allocated for it, the system selects a new process to execute. The fact that all processes only execute for a very short period until a new one is selected makes it transparent that you really only have one processor. The details differ between the various systems, but the concept is the same.

Woah dude, relax.... I've never heard the term before. But, I definately know what true-multitasking is and that it's simulated by a single processor.

My comment wasn't directed to you, but the other three contributors :)

Oh, in that case, continue...;)
