Users also tended to watch more content on the same subject, so the AI led people into filter bubbles where they received multiple versions of the same misinformation. [235] This convinced many users that the misinformation was true, and ultimately undermined trust in institutions, the media and the government. [ 236 ]
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
This machine invented the principle of the modern computer and was the birthplace of the stored program concept that almost all modern day computers use. [52] These hypothetical machines were designed to formally determine, mathematically, what can be computed, taking into account limitations on computing ability.
The additionally advanced Analytical Engine combined concepts from his previous work and that of others to create a device that, if constructed as designed, would have possessed many properties of a modern electronic computer, such as an internal "scratch memory" equivalent to RAM, multiple forms of output including a bell, a graph-plotter, and ...
Usually heterogeneity in the context of computing refers to different instruction-set architectures (ISA), where the main processor has one and other processors have another - usually a very different - architecture (maybe more than one), not just a different microarchitecture (floating point number processing is a special case of this - not usually referred to as heterogeneous).
A more interactive form of computer use developed commercially by the middle 1960s. In a time-sharing system, multiple teleprinter and display terminals let many people share the use of one mainframe computer processor, with the operating system assigning time slices to each user's jobs. This was common in business applications and in science ...
Multiple autonomous processors simultaneously executing the same program (but at independent points, rather than in the lockstep that SIMD imposes) on different data. [19] Also termed single process, multiple data [ 17 ] - the use of this terminology for SPMD is technically incorrect, as SPMD is a parallel execution model and assumes multiple ...
It was the first known geared mechanism to use a differential gear. The chariot was a two-wheeled vehicle, upon which is a pointing figure connected to the wheels by means of differential gearing. Through careful selection of wheel size, track and gear ratios, the figure atop the chariot always pointed in the same direction. c. 125 BC
