Using a "worker" or "worker name" is often an option when you do pool mining. It is often exemplified by "rig1". But how do you create one, and what is its use?

A mining rig is a computer system used for mining bitcoins. The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis. wiki
