14、owing a passage on the basis of what is stated or implied in the passage. 17 Electronic computer speeds are restricted not only by the speed of electrons in matter but also by the escalating density of interconnections necessary to connect the electronic gates on microchips. Electrical engineers and
15、 physicists have been developing and augmenting the technologies of analog and digital (5) optical computing, in which the information is primarily carried by photons rather than by electrons. Optical computing could, in principle, generate much higher computer speeds, but one of the problems it has
16、 encountered lies in accuracy, for these devices have practical limits of 8 to 11 bits of accuracy in basic operations. Recent research has evinced that digital partitioning (10) algorithms in tandem with error-correction codes, can substantially enhance the accuracy of optical computing operations.
17、 In the near term optical computers will most likely be hybrid optical/electronic systems that preprocess input data for computation and post-process output data via electronic circuits, but nevertheless, the prospect of all-optical computing remains highly attractive. 17 According to the passage, w
18、hich of the following is true concerning optical computers? ( A) Researchers have not yet discovered a means of transporting photons more efficiently. ( B) Their primary limitation is the density of connections required between electronic microchip gates. ( C) Their accuracy level is poor at 8 to 11
19、 bits, but still superior to that Of electronic computers. ( D) They invariably rely on electronic circuits to preprocess input data for computation. ( E) Both analog and digital forms of optic computing are presently being developed by scientists. 18 It can be inferred from the passage that the aut
20、hor would be more optimistic about optical computing if which of the following were true? ( A) Digital partitioning algorithms could be applied to electronic, and not just optical circuits. ( B) The speed of photons could be shown to be significantly greater than that of electrons. ( C) The precisio
21、n level in basic operations can be substantially increased without great expense. ( D) The accuracy of electronic circuits used to preprocess input data and post- process data could be greatly increased. ( E) The microchips optical computer systems were shown to require an increasing density of inte
22、rconnections. 19 Which of the following can be inferred from the passage about the technology employed in optical computing? ( A) The technology is more expensive to develop than the technology that was required in electronic computing. ( B) The search for technology necessary for all-optical comput
23、ing is considered unfeasible and has been largely abandoned. ( C) Optical computers systems that rely on digital partitioning algorithms in tandem with error-correction codes are considered hybrid technology. ( D) The technology necessary for digital optical computing appears within closer reach tha
24、n the technology for analog optical computing. ( E) The most feasible version of optical computing at present is a synthesis of electronic and optical technology. 20 The passage suggests that the author would most probably agree with which of the following assessments of optical computing in its pre
