（XDF）59
Electronic computer ships made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electric switches that are this small cannot withstand intense radiation. M plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage. The switches will, however, be slower than electronic switches and the chip will contain only 12000 switches.
For there to be a market for M’s chip as a result of the apparent advantage describedabove, each of the following would have to be true…….
(d) Some devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation. (这个答案怎么解释为正确的？) |
