第2章 发展篇(2)

This kind of insert adopt PCI Expres interface technology.The characteristics of the PCI Expres are upgrading quality,low cost with high performance,high expanding and high dependability.It will replace the present PCI bus in the future.We can design and publish the concept machines of modularization by the plug and play characteristic.The picture below is a concept machine of modularization that was shown by some manufacturers which DELL inclusive on WinHEC 2002.When we need some function,we just have to add a model provides the function to the computer,does not need shut down.It is convenient just like to use USB equipment.Perhaps the computer in the future will be a piece of airtight equipment,all peripheral hardware will be joined through USB or other outside interface.

这种插槽将采用PCI Expres接口技术,PCI Expres具有高性能、高扩展性、高可靠性、很好的升级性以及低花费的特点,它必然取代现在的PCI总线。同时利用它的热插拔原理我们可以设计出模块化的概念机,下图是DELL在内的一些厂商已经在WinHEC 2002上展示的模块化的概念机,当我们需要哪一个功能时,只需要把提供该功能的模块加到机子上,就能提供该功能,无需关机,就像现在使用USB设备一样方便。也许未来的计算机将是一个密封设备,所有外设都将通过USB或其他外部接口连接。而计算机板卡也通过PCI Expres总线,从而支持热插拔。

Wirelessly

无线化

Pursues freely is always humanity’s dream.The computer’s the wirelessization is also what people dream of.In the future will computer achieve the wireless between equipment and the network,which means the PCs at home will be more convenient than the laptop-computer in the future.Because the display (certainly will not have been CRT)will be connected wirelessly with host computer,which a little look like present Tablet PC.

追求自由一直是人类的梦想,计算机的无线化风潮同样也是人们梦寐以求的,和现在笔记本讲的“无线你的无限”有所不同的是:未来的计算机将实现网络和设备间的无线连接,这将意味着未来在家中使用台式机比现在的笔记本还方便,因为显示器(当然不会是CRT的)与主机之间也是通过无线来连接的,使用起来有点像现在的Tablet PC。

The technology which will finish this kind of dream is called UWB(Ultra WideBand)technology.It is a kind of wireless communication technology that very different from others.It is a simple wireless communication technology which can make low consumptions and high bandwidth at wireless LAN WLAN and personal LAN insert technology.So INTEL call it wireless USB.

实现这种梦想的技术称为UWB(Ultra WideBand)技术,它是一种与其它技术有很大不同的无线通信技术,它可以为无线局域网WLAN和个人局域网LAN的接口卡和接入技术带来低功耗、高带宽并且相对简单的无线通信技术,所以INTEL称它为无线USB,希望能够成为计算机与计算机或是计算机与消费电子产品(如数字相机)间的高频宽的无线连接。

The transmission speeds of UWB reach 400to 500mbps in short distance (probably each).At present,super broadband technology can make two equipments apart from mutually 30foot travel signals to each other at the speed of 100mbps.In the experiment that is carried on recently,Xtreme Spectrum have utilized its chip to convey different digital TV signals to 6televisions at the same time.UWB的传输速度在相对上较短的距离内(大约是15英尺)可达400及500mbps之间,目前超级宽带技术已经能够使两个相距30英尺的设备通过无线方式以100mbps的速度传播信号。在最近进行的实验中,Xtreme Spectrum利用其芯片同时向6台电视机传送不同的数字化电视信号。But there is only 30feet of transmission distances at present,which make UWB technology still unable to compete with 802.11and any other technology for the market of home network.The research and development of UWB is not being given up.The investigator have researched on strengthen the signal of UWB now,and hope its effective function can cover the family in distance.UWB will be used in the communication among various kinds of devices of computer at the same time,not merely be used it in the network of the computer.

但是目前只有30英尺的传输距离,使得UWB技术还无法与802.11等其他技术竞争家用网络市场,UWB的研发并没有放弃,技术人员正在进行增强UWB信号的研究,希望使其有效作用距离能够覆盖家庭。同时UWB将会定义用于各种计算机装置和部件间的沟通,而不单单应用在计算机的网络上。

Specialization

专门化

Actually not every pieces of jobs needed a high-performance PCs to finish.Even adopt the high-performance computer and may bring the trouble sometimes.Because high performance certainly will bring bad negative effects,such as high energy consumption,high caloric value,etc.Computers in the future will be different on the appearance on performance because of different work require.PC in common use will be replace by the dedicated device (the computer that the software and hardware will be integrated)gradually in order to improve working efficiency.

其实并不是每一件工作都需要一部高性能的PC才能完成,甚至是有时候采用高性能的计算机还有可能带来麻烦,因为高性能势必带来高能耗、高发热量等不良的负面效应。将来的计算机由于从事的工作不同,在性能上在外形上都会有很大的不同。通用PC将逐渐由专用设备(软硬件一体化的计算机)所代替,以提高工作效率。

If you look out for carefully,actually such a change is taking place too at our side at present.For example the terminal station of the lottery ticket,the terminal stations of the cash registering machine in the market and bank,etc.They were all developed gradually by PC in common use for reducing the cost for the efficiency.如果您仔细留意的话,其实目前在我们的身边也正在发生这样的变化,比如售卖彩票的终端、商场里的收银机、银行的终端等等,多是为了提高某一项工作的效率和减少成本,逐渐由通用PC逐渐演变而来的。Perhaps such trend will appear among the family lives of us,too.The special-purpose family adjust and control computer become the controls centre of electric apparatus of home,control electric light,refrigerator,microwave oven,air conditioner in home,etc.for us,to turn our family into a family of intelligence.

也许这样的趋势出现在我们的家庭生活中,专用的“家庭调控计算机”将成为家中的电器控制中心,为我们控制家中的电灯、冰箱、微波炉、空调等等,把我们的家变成一个智能的家。

Networked

网络化

Computer is already popularized more and more,various kinds of household appliances begin to possess intelligently too.These phenomenon promote electrical home appliances and the networked processes of computer.The computer can control the function of different electrical home appliances through the network,and download various kinds of new electrical home appliances application program through Internet,in order to increase the functions and improve the performance of the electrical home appliances.We can also let the electric apparatus in home do something through the electrical home appliances in the long-range remote control family of Internet such as improve performance boil the good dish,open air conditioner,etc.

计算机已经越来越普及,各种家用电器也开始具备了智能化,这些现象将促进家电与计算机的网络化进程,家庭网络分布式系统将逐渐取代目前单机操作的模式,计算机可以通过网络控制着各种家电的运行,并通过互联网下载各种新的家电应用程序,以增加家电的功能,改善家电的性能等等。也可以通过互联网远程遥控家中的家电,在办公室的时候就可以提前让家中的电器做好饭,煮好菜,开空调等等。
