14.Computer technology is still developing rapidly.The computer of the future will continue to increase in value and performance while decreasing in cost.It will become smaller,but faster and more powerful.
It is possible to make some guesses about what the future of the computer will look like,based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies,but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing (量子計算) and nanotechnology (納米技術(shù)).
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.
Nanotechnology could also change the face of computing,by creating computers that could be very powerful,though they are tiny in size.These computers could be incorporated (并入) into everyday objects,including electrical appliances (電器),clothes and even the human body.We will be able to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes,such as work.
Quantum computing and nanotechnology will be able to play new roles,which will make us live greener lives,as well as enjoy better health and happier lives.
