 | CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. |
| In 1964 IBM introduced its System/360 computer architecture, which was used in a series of computers that could run the same programs with different speed and performance. |
| These newer concerns are among the many factors causing researchers to investigate new methods of computing such as the quantum computer, as well as to expand the usage of parallelism and other methods that extend the usefulness of the classical von Neumann model. |
