Computers will become more advanced and they willalso become easier to use. Improved speed recognition will make the operationof a computer easier. Virtual reality (虛擬現(xiàn)實(shí)), the technology of （1）witha computer using all of the human senses, will also contribute to better humanand computer （2）. Other, exotic (奇異的) models of computation arebeing developed, including biological computing that uses living organisms,molecular computing that uses molecules with particular （3）, and computingthat uses DNA, the basic unit of heredity (遺傳), to store data and carry outoperations. These are examples of possible future computational platforms that,so far, are limited in abilities or are strictly （4）. Scientists investigatethem because of the physical limitations of miniaturizing circuits embedded insilicon. There are also （5）related to heat generated by even the tiniest oftransistors.
