Bitcoin mining worker
What is the difference between mining with multiple workers vs single?
Depends. Generally you'd use multiple workers when you have multiple machines (ie graphics cards, mining rigs, or a farm of USB sticks). In some cases you could have them all combined and contributing to a single worker but usually this is not desirable because you'd want to keep track of how each device is performing.
If for no other reason, that certainly makes it easier to tell which one has crashed or is not working when problems arise.
