Finally, tasks required of modern computers often emphasize quite different components, so that resolving a bottleneck for one task may not affect the performance of another. For these reasons, upgrading a CPU does not always have a dramatic effect. The concept of being CPU-bound is now one of many factors considered in modern computing ...
True photographic memory (the ability to remember endless images, particularly pages or numbers, with such a high degree of precision that the image mimics a photo) has never been demonstrated to exist in any individual, [471] although a small number of young children have eidetic memory, where they can recall an object with high precision for ...
Additional hardware support for multithreading allows thread switching to be done in one CPU cycle, bringing performance improvements. Also, additional hardware allows each thread to behave as if it were executing alone and not sharing any hardware resources with other threads, minimizing the amount of software changes needed within the ...
A distant object is defined as an object located beyond 6 meters (20 feet) from the eye. [citation needed] When an object is located close to the eye, the rays of light from this object no longer approach the eye parallel to each other. Consequently, the eye must increase its refractive power to bring those rays of light together on the retina.
Several decades of rapid progress in areal density slowed around 2010, from 30 to 100% per year to 10–15% per year, because of noise related to smaller grain size of the disk media, thermal stability, and writability using available magnetic fields.
StatCounter web usage data of desktop or laptop operating systems varies significantly by country. For example, in 2017, macOS usage in North America was at 16.82% [99] (17.52% in the US [100]) whereas in Asia it was only 4.4%. [101] As of July 2023, macOS usage has increased to 30.81% in North America [102] (31.77% in the US) [103] and to 9.64 ...
For example, the task of generating high-resolution face images from low-resolution inputs is called face hallucination. [ 15 ] [ 16 ] In the late 2010s, the term underwent a semantic shift to signify the generation of factually incorrect or misleading outputs by AI systems in tasks like translation or object detection .

Power usage effectiveness (PUE) or power unit efficiency is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment).
