The Full Form of NUC is‍ Next Unit of Computing.

Next Unit of Computing (NUC) is a line of small-form-factor barebone computer kits designed by Intel. The NUC has had ten generations so far, spanning from Sandy Bridge-based Celeron CPUs in the first generation through Ivy Bridge-based Core i3 and i5 CPUs in the second generation to Gemini Lake-based Pentium and Celeron CPUs and Kaby Lake-based Core i3, i5, and i7 CPUs in the seventh and eighth generations. The NUC motherboard usually measures approximately 4 × 4 inches (10.16 × 10.16 cm), although some models have had different dimensions.

Intel’s Next Unit of Computing (NUC) is the latest motherboard which shows just how much computing power can be packed into a device that is barely larger than the palm of your hand.

Last year Intel launched motherboards based on its Thin-ITX form factor, a tweak on the long-standing Mini-ITX standard. Now the firm has gone a step further with its NUC design, shrinking the motherboard down to 4x4ins and despite its diminutive characteristics, the NUC punches well above its weight.
