Cmputer technlgy is still develping rapidly.The cmputer f the future will cntinue t increase in value and perfrmance while decreasing in cst.It will becme smaller，but faster and mre pwerful.
It is pssible t make sme guesses abut what the future f the cmputer will lk like，based upn the types f technlgies that are being develped nw.A lt f prgress has already been made in sme f these new technlgies，but sme are still in their earliest stages and may nt be ready fr use fr years.Tw f the mst interesting areas f cmputing that are currently being develped are quantum cmputing (量子计算) and nantechnlgy (纳米技术)．
Quantum cmputing is ne pssibility fr the future f the cmputer that culd make cmputers run far faster than even the quickest cmputers d tday.Quantum cmputers culd be able t d what mdern supercmputers are unable t d by using transistrs that are able t take n many states at the same time.
Nantechnlgy culd als change the face f cmputing，by creating cmputers that culd be very pwerful，thugh they are tiny in size.These cmputers culd be incrprated (并入) int everyday bjects，including electrical appliances (电器)，clthes and even the human bdy.We will be able t use cmputers in new and unimaginable ways.They will becme a part f ur lives rather than simply being a bx that is used nly fr specific purpses，such as wrk.
Quantum cmputing and nantechnlgy will be able t play new rles，which will make us live greener lives，as well as enjy better health and happier lives.
