提高英语听力能力 找对方法很重要!
Many tech folk think we have entered what steven jobs liked to call a post PC era.This doesn't mean that PCs are about to diappear.Shipments of them will keep growing,especially in emgering markets hungry for computing power.But smart phones and tablet computers are puting PCs in the shade.This year combined shipments of two devices are likely to outstrip those of PCs for the first time and they will keep growing strongly.In many rich countries,smart phones now outnumber more basic feature phones. And in emerging markets,such as China and India,they are expected to catch up with feature phones too.Downloadable software applications or apps have helped to make these tablets and smart phones so popular.Almost 18 billion apps will be downloaded this year and that number will soar as more mobile devices are sold.Many of these apps are free,but a few are used regularly,one study found that the ten most popular Android apps accounted for 43 percent of all usage, and the top 50 for almost two third of it. As mobile gadgets have become more powerful,they are being used more at work.In 2010, 31 percent of devices used by information workers to access things such as spreadsheets and customer detabases with their own.This year that number leapt to 41 percent partly because of the impact of the tablet computers,tech types refer to this as consumerization of IT.Although the number of PCs in use has risen over time,also sorts of mobile,web connected devices are now taking off.Some 10 billion of these could be in circulation by the end of decade.This will produce an explosion of mobile date.By 2015 some 6.3 exabytes of the stuff will be zipping around each months which is the equivalent of the 63 billion copies of the economist.Fortunately,much of mobile data will be in the form of videos like the one you are watching now.
