How Quantum Computers and Machine Learning Will Revolutionize Big Data - Wired Science | Science, Technology, and Current Futurism |

since 2005, many of the gains in computing power have come from adding more parallelism via multiple cores, with multiple levels of memory. The preferred architecture no longer features a single central processing unit (CPU) augmented with random access memory (RAM) and a hard drive for long-term storage. Even the big, centralized parallel supercomputers that dominated the 1980s and 1990s are giving way to distributed data centers and cloud computing, often networked across many organizations and vast geographical distances.
