Computers will become more advanced and they willalso become easier to use. Improved speed recognition will make the operationof a computer easier. Virtual reality (虚拟现实), the technology of （1）witha computer using all of the human senses, will also contribute to better humanand computer （2）. Other, exotic (奇异的) 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 (遗传), 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）.
