Michigan's and IBM's tiny "computers" have people questioning the definition of "computer"

When it announced the "Michigan Micro Mote", Michigan (and its researchers) had created the tiniest computer in the world. Not to be outdone, IBM seemingly created a "computer" even smaller which it announced back in March. However, Michigan researchers have created an even smaller "computer" at around 1/4 of the size of IBM's.

Michigan's newest "computer" is dwarfed by a grain of rice

However, what is the real definition of a computer?

It is widely accepted that the Michigan Micro Mote is a legitimate computer. However, there seems to be disagreement on whether IBM's or Michigan's new devices count. Do they have processors, transmitters, and RAM like other computers? Yes they do. Power source? Check. Ability to retain information with power loss? Negative, and that might be the key difference.

When a computer is unplugged or loses power, the data and programming are maintained by the computer. When power is restored, everything is still there. The Micro Mote maintained that ability while in a much smaller size. However, the two new, smallest" computers" are clean slates as soon as power is lost. That could be problematic.

IBM 's tiny "computer" may not be a "real" computer

Are these devices still useful with powerful future plans? Absolutely. The current plans for these devices include detecting temperature changes on a cellular level that could possibly change how we view tumors and cancer treatments. These devices could have tremendous potential, and their "computer" status will not change that. However, in terms of recognition, the definition of "computer" could determine who is the best.
