Multi-tasking is a sort of generic term that can mean almost anything, so I'm guessing that you might be referring to multi-threading. (To my knowledge and recollection, multi-tasking is more of a layman's term) Multi-threading is one process (or application) executing multiple "threads" or tasks in parallel. For instance, it might be faster to divide up a large math problem into three parts and execute them in parallel. A single processor can't actually execute the threads simultaneously; rather, it quickly switches from one thread to the next, giving each thread a share of time to use. This happens so quickly that it appears to be in parallel.

Multi-processing is dividing a given task into several smaller tasks and delegating those tasks to more than one processor.

Multi-threading (or "multi-tasking") may be used on one or more processors and is not limited to multi-processor machines.

There's a lot more to it, but that's a start.
