One technique of how this parallelism is achieved is through multiprocessing systems, computer systems with multiple CPUs. In the past this was reserved for high-end mainframes but now small scale (2-8) multiprocessors servers have become commonplace for the small business market. For large corporations, large scale (16-256) multiprocessors are common. Even personal computers with multiple CPUs have appeared since the 1990s.
