Mining hardware takes care of the mining process, but it is also important to have efficient software for the best results and the removal of bottlenecks, if any.
The task of the mining software is to share the mining task of the hardware over the network. Apart from this, its task is to receive work from other miners on the network. Based on the operating system the hardware is running, there is various mining softwares available, such as BTCMiner, CGMiner, BFGMiner, Nheqminer, and so on:
Mining software should be chosen on the basis of the operating system, hardware type, and other factors. Most mining software is open source and has a large amount of active community to clarify any doubts in choosing the correct software for the available hardware to the miner.
