数据通信系统
            Data Communication Systems

              There are five basic types of data communication system:

              Off-line data transmission is simply the use of a telephone or
            similar link to transmit data without involving a computer system
            .The equipment used at both ends of such a link is not part of a
            computer, or at least does not immediately make the data available
            for computer process, that is, the data when sent and/or received
            are 'off-line'. This type of data communication is relatively cheap
            and simple.

              Remote batch is the term used for the way in which data
            communication technology is used geographically to separate the
            input and /or output of data from the computer on which they are
            processed in batch mode.

              On-line data collection is the method of using communications
            technology to provide input data to a computer as such input
            arises-the data are then stored in the computer (say on a magnetic
            disk) and processed either at predetermined intervals or as
required.

              Enquiry-response systems provide ,as the term suggests ,the
            facility for a user to extract information from a computer .The
            enquiry facility is passive ,that is ,does not modify the
            information stored .The interrogation may be simple ,for example
            ,'RETRIEVE THE RECORD FOR EMPLOYEE NUMBER 1234' or complex .Such
            systems may use terminals producing hard copy and /or visual
            displays.

              Real-time systems are those in which information is made available
            to and processed by a computer system in a dynamic manner so that
            either the computer may cause action to be taken to influence events
            as they occur (for example as in a process control application) or
            human operators may be influenced by the accurate and up-to-date
            information stored in the computer, for example as in reservation
            systems.

              有五种基本的数据通信系统:

              脱机数据传输是简单地利用电话或类似的链路来传输数据,不包括计算机系统。这样一条链路两端所使用的设备不是计算机的部件,或至少不是立刻把数据提供给计算机处理,即数据在发送或接收时是脱机的。这种数据通信相对来说比较便宜和简单。

              远程批处理一词适用于这样一种方法:采用数据通信技术来使数据的输入和输出在地理上远离按批处理模式处理处理它们的计算机。

              联机数据收集指的是用数据通信技术来向计算机即时提供刚产生的输入数据这种方法。数据于是存储在计算机里(比如磁盘上),并按预定时间间隔或者根据需要进行处理。

              询问--应答系统,顾名思义,是为用户提供从计算机提取信息的功能。询问功能是被动的。也就是说,它不修改所存储的信息。提问可以很简单,例如:"检索雇员号码为1234的记录"也可以是复杂的。这类系统可能要使用能产生硬拷贝和(或)可视显示的终端。

              实时系统是这样一类系统,其中计算机系统是在动态情况下取得和处理信息,以便可使计算机采取动作来影响正在发生的事件(比如在过程控制应用中)或者可通过存储在计算机里的准确且不断更新的信息来影响人(操作员),比如在预售系统中。

A Cold War in Cyberspace
he growing rivalry between AOL Time Warner and Microsoft is
            spawning a web of deals and alliances, which could mean good news
            for consumers.

              Two titans are left standing in the wake of the dot-com collapse.
            There's AOL Time Warner (AOL ) spanning media, Internet access, and
            cable television. Equally formidable is Microsoft, cutting its
            impressive swath through the software world. Talks between the two
            recently broke down over how Microsoft's much-anticipated XP
            operating system would interact with AOL's Internet services. That
            has fueled much speculation over which company will emerge
            victorious in the battle for the loyalty of a new generation of
            Netizens.

              Billed as the ultimate cyberwar, it's likely to be a complicated
            affair with a lot of Cold War sparring, alliance-building, and
            grabbing of strategic tech territory. While Microsoft and AOL
            compete directly in such areas as dial-up access, instant messaging,
            and interactive TV, there are many others where they don't. For
            instance, AOL doesn't have an operating system, and Microsoft isn't
            a media company. It's in these no-contact zones where the Cold War
            is most active.

              Both giants are busy forming alliances to create new spheres of
            influence. And the propaganda is hot and heavy, too. "We
            fundamentally don't think that consumers should be left with the
            same choice in music players or anything else that they're left with
            in spreadsheets, [word-processing] programs, and other...software.
            That's a choice of MS or nothing at all," argues John Buckley, AOL
            Time Warner's vice-president for corporate affairs.

              WORTHY OPPONENTS. Do consumers stand a chance in a market carved
            up by two corporate superpowers? Surprisingly, the answer may be
            yes. For the first time in a decade, AOL and Microsoft each face an
            adversary with real clout. Ultimately, an unwinnable war may keep
            competition healthy in important emerging markets, such as digital
            media, electronic games, and cable.

              Witness the battle over streaming-media technology. AOL doesn't
            make a media player -- but it wants to make sure that someone
            besides Bill Gates and Steve Ballmer does. So it's building a strong
            alliance with RealNetworks, Microsoft's competitor in streaming
            technology. The Seattle-based company is the market leader, with
            more than 200 million registered users. But RealNetworks, founded by
            former Microsoft employee Rob Glaser, has had a tough time spinning
            cash from those users. That's particularly true since Microsoft
            gives its similar Windows Media Player away free as part of its
            ubiquitous Windows operating system.

              AOL is giving RealNetworks maximum backing. Last July, AOL
            announced that it would bundle RealNetworks' RealPlayer into the
            newest version of AOL, 6.0, giving RealNetworks access to AOL's 30
            million-strong subscriber base. On Apr. 2, AOL chose RealNetworks as
            a partner for its upcoming music-subscription service, MusicNet.

              The service, a partnership between Time Warner Music, EMI, and
            BMG, will offer a wide collection of downloadable and streaming
            music backed by RealNetworks' technology. "Whether it's a portable
            device, a game machine, or something else, if you don't want to be
            sucked into the world of Windows, you need another alternative,"
            says one digital-media expert. "Clearly Real is becoming a tool of
            companies that don't want to do everything with Windows."

              GAME PLAN. Online gaming is another area both AOL and Microsoft
            covet. Once video games are routinely connected to the Net, the
            console becomes a valuable platform, much like the PC, from which
            ads, music and, of course, video games can be sold. On May 15, AOL
            struck a deal with Sony to include its e-mail and instant messaging
            programs in the next version of PlayStation 2.

              In exchange, Sony will build an adapter into the game console that
            allows consumers to access AOL Internet features and play
            Net-enabled games. By yearend, Sony also will include RealNetworks'
            RealPlayer and RealJukebox software on hard drives that can be added
            to PlayStation 2 consoles.

              The furious dealmaking by AOL is all aimed at blunting Microsoft's
            steady move into the market. On Nov. 8, Gates & Co. will launch the
            new Xbox game system in a $500 million marketing blitz that is sure
            to cause damage. Gaming "isn't a core area for either AOL or
            RealNetworks, but neither wanted to cede it to Microsoft," says John
            Corcoran, an analyst at CIBC Markets in Boston.

              Microsoft is likewise making defensive alliances in areas of AOL
            strength, such as cable TV, though it plays down the notion that
            keeping AOL in check is of strategic importance. "We're moving ahead
            with a strategy that relies a lot on third-party support. But it's
            up to AOL to decide how they want to partner with Microsoft," says
            company spokesman Jim Cullinan. Since 1997, Microsoft has invested
            $1 billion in Comcast (CMCS ) and $5 billion in AT&T (T ) to ensure
            that it keeps a big hand in the development of interactive TV.

              "Microsoft is working hard to become a player in the cable
            industry. And the industry has anointed Microsoft as one of the two
            players in the interactive-TV space," says Michael Goodman, a cable
            analyst at the Boston research firm Yankee Group. While such
            investments don't directly undermine Time Warner cable properties,
            they help keep rival cable operators on the digital edge.

              BOOSTING SUN. Meanwhile, AOL is keen on building solidarity with
            other companies in the anti-Microsoft camp. In January, AOL gave
            Microsoft archrival Sun Microsystems (SUN ) a big boost in a time of
            slumping sales by purchasing $400 million in products and services.
            That's on top of the $500 million worth of equipment it AOL bought
            in 1998. AOL now uses more than 4,000 Sun servers.

              More recently, Microsoft moved to test the loyalty of AOL's 30
            million dial-up network users. When AOL hiked its prices by 9% in
            May, MSN's prices stayed flat, and it offered three months of free
            service to new customers. Gates & Co. also spent $50 million in the
            market push. So far, AOL claims the price hike hasn't hurt it.

              Clearly, a digital world dominated by these titans is a long way
            from the wide-open markets that many analysts were predicting only
            18 months ago. The not-so-bad news is that the new battle for the
            Net is between two well-oiled machines, with lots of cash and plenty
            of incentive to innovate and keep their competitive edges sharp.
            Without AOL, RealNetworks might have gone the way of Netscape.
            Microsoft's deep pockets keep AOL from dial-up domination. While
            neither superpower may win, the consumer just might.

            参考译文

              随着微软进军互联网,AOL-TW遭遇到前所未有的强大敌手。互联网上,一场冷战打响了。

              两大巨人依然屹立在互联网坍塌的废墟中。一个巨人是AOL时代华纳公司,势力范围包括媒体、互联网接入和有线电视;另一个巨人是微软,它是软件业的霸主。最近,两大巨人在微软XP操作系统与AOL在线网络服务如何互动的问题上没能取得一致,双方谈判失败。谈判失败营造出一个悬念:AOL和微软在争夺新一代网民的战斗中,谁将最后取胜呢?

              这场战斗堪称互联网超级大战,双方将运用“冷战”谈判、结盟、占领技术制高点等各种战术。一方面,微软和AOL在拨号上网、短消息服务和互动电视等领域短兵相接;但另一方面,他们有很多领域没有短兵相接,比如AOL没有操作系统,而微软没有媒体公司。但是,恰恰是在这些没有短兵相接的领域,冷战显得最为激烈。

              目前,两大巨人到处寻找盟友,试图营造新的势力范围。AOL时代华纳的副总裁约翰.巴克利(John
            Buckley)辩称:“我们坚信,消费者在音乐播放等方面不应该只有一个选择。但是,消费者在电子表格、文字处理及其它软件方面却只有一个选择,那完全是微软的选择!”约翰的话语十分辛辣,却十分沉重。

            两大对手势均力敌

              两大超级巨人霸占了整个市场,消费者能够从中得利吗?答案是肯定的。十多年来,AOL和微软破天荒第一次遇到了真正的敌手,最终的结果将是谁也无法在这场战斗中取胜,从而使数字媒体、电子游戏和有线电视等市场处于一个良性竞争。

              以媒体播放技术的竞争为例。AOL在媒体播放技术领域不是主角,但希望有除比尔.盖茨和史蒂夫.巴尔默以外的其它人来扮演主角。所以,AOL与微软的主演竞争对手RealNetworks建立了深厚的盟友关系。RealNetworks在市场上处于领先地位,拥有2亿多注册用户。但是,该公司虽然拥有庞大的用户,但一直无法向用户收费,特别是微软在Windows操作系统中免费搭配上Winfows
            Media Player以后,RealiNetworks更加难于向用户收费了。

              AOL向RealNetworks公司提供了最大限度的支持。去年7月,AOL宣布在自己的最新版AOL6.0软件中搭配安装RealNetworks公司的RealPlayer播放器,使RealNetworks直接面向AOL的3000万用户。今年4月2日,AOL选定RealNetworks公司作为即将推出的MusicNet音乐订购服务的合作伙伴。

              MusicNet音乐订购服务是由时代华纳音乐唱片公司、百代唱片公司(EMI)和BMG古典音乐世界三家公司联合推出的,在RealNetworks公司的技术支持下,向人们提供各种可供下载的数字音乐。据一名数字媒体专家表示,RealNetworks向人们提供了一个选择余地,使Windows不能独专。

            游戏计划

              在线游戏是AOL和微软垂涎三尺的另一个领域。视频游戏一旦联网,游戏机将成为一个类似于PC的平台,可以销售广告、音乐等服务。5月15日,AOL与索尼达成了一项交易,允许索尼在PlayStion2下一代产品中安装AOL的e-mail和即时短消息收发软件。交换条件是,索尼将在游戏机中安装上一个适配器,允许消费者访问AOL的互联网内容以及在线游戏。今年年底,索尼将在硬盘上安装RealNetworks的RealPlayer和RealJukebox软件,然后把硬盘直接安装到PlayStation2游戏机上。


              AOL达成的一系列交易只有一个目的,那就是阻止微软长驱直入,挫败微软的锐气。11月6日,微软即将推出Xbox新一代游戏系统,号称要投资5亿美元打一场闪电战。据波士顿CIBC市场调查公司的一名分析家说:“游戏并不是AOL和RealNetworks公司的核心业务,但他们不想对微软拱手相让。”

              在AOL的势力范围(如有线电视),微软采取的是防御性结盟战略,尽管微软保持低调,称与AOL结盟具有重要的战略意义。微软的发言人说:“我们采取依靠第三方支持的战略向前推进。但是否与AOL合作,关键要看AOL希望与微软达成怎样的合作关系。”自1997年,微软已在Comcast公司和AT&T公司分别投资了10亿和50亿美元,以保证自己在互动电视的发展中保持强大的势力。

              据波斯顿调查公司Yankee
            Group的一名分析家说:“微软一直致力于在有线电视领域取得一席之地。目前,业界已推举微软是互动电视领域的两大竞争者之一。”微软的投资虽然不能直接撼动时代华纳公司在有线电视的霸主地位,但毕竟给AOL构成了一定威胁。

            AOL助推Sun微系统公司

              与此同时,AOL热心于团结反微软阵营中的其它公司。1月份,AOL向微软的死对头Sun微系统公司购买了价值4亿美元的产品和服务,在销售如此不景气的情况下着实推了Sun微系统公司一把。目前,AOL拥有4000多台Sun服务器。

              反过来,微软于最近考验了AOL的3000万拨号上网用户对AOL的忠实度。AOL在5月份把服务价格上涨了9%,而MSN的价格却保持不变,同时向新用户提供三个月免费服务,而且微软投资了5000万美元用于市场促销。到目前为止,AOL宣称提价还没有造成伤害。

              很明显,由这些巨人主宰的数字世界还远远不能称其为完全敞开的市场,但值得庆幸的是,这场战争在两大巨人之间展开,他们拥有大量的现金、足够的创新和争胜精神。如果没有AOL的帮助,RealNetworks可能只有落得个像Netscape一样的命运;相反,微软的雄厚资金阻止了AOL独霸拨号上网业务。两大超级巨人可能谁也无法取胜,只有消费者可能渔翁得利。

Yahoo is planning to launch a newly redesigned home page that features a cleaner layout and a better showcase for advertisers,according to sources familiar with the changes.The online portal,which has maintained the basic framework of its home pages ince 1995,will introduce the new site about mid-June,according to one source.Yahoo is currently hosting a user survey to gauge how Web surfers view the site's performance and usability.


There design is being fueled partly by advertisers,which are increasingly demanding more real estate on highly visible spots such as Yahoo's home page.Advertisers are irked 1 that they can only buy minimal exposure on the main page of a site that draws a massive audience.The site sells a banner that is half the standard size of comparable ads on the Web.It also sells a square ad,or what it calls a“mantle”ad,in the center of its page for video or rich-media ads.


Yahoo has long tried to keep graphics intensive or intrusive ads to a minimum on its home page because the ads can inhibit speed and performance—key principles held with near religious fervor by Yahoo co-founder David Filo since the site first launched.

Increasingly,however,the Web portal is under pressure to cater to advertisers that could reverse a steep decline in its revenues.The company has stepped further in this direction since Yahoo brought in Hollywood veteran Terry Semel as chief executive last year.

Yahoo declined to comment on the pending changes.But Jeff Wiener,senior vice president of corporate development at Yahoo,said in a recent interview with CNET Radio that to some extent,there have been several iterations 2 of the Yahoo home page in the last seven years.He added that Web visitors can look forward to “innovation and change on the home page and throughout the site,”as well as in its search and directory.


The home page overhaul 3 comes as the Web portal has introduced pronounced changes throughout the site,adding fees to services that had previously been offered for free and placing large,animated ads in popular areas such as finance,sports,news and e-mail,among others.By contrast,the home page largely has been hands off,although Yahoo has loosened its stance in recent months by allowing more invasive 4 ads onto it—including a Ford Motor promotion that temporarily took over visitors' screens entirely.

电子墨水与纸
            Electronic Ink and paper
              Cambridge,Mass.-based E Ink Corp.is a leader in the development of
            electronic ink and “paper”that could replace newspapers and books as
            we know them today.

              The use of electronic ink and two-way wireless communication could
            lead to the creation of electronic books that will renew themselves
            with new selections when readers are finished with the current
            book——or newspapers that update themselves with the latest news
            while being read.

              Electronic ink,as devised by E Ink,is a clear,liquid plastic in
            which there are microcapsules that contain white chips in a blue
            dye.The microcapsules are suspended in a substance similar to
            vegetable cooking oil.The white chips are negatively charged so they
            react to electrical stimulus.

              This ink can be spread on any surface——from walls to computer
            screens——says Russell Wilcox,vice president and general manager at E
            Ink.However,the writing surface would look similar to a very thin
            laptop display screen with a clear surface on the front and
            circuitry on the back.

              A positive charge applied on the top surface of the ink will allow
            the white to show,making the surface as white as a sheet of paper.If
            the charge moves to the bottom,the dark particles will show,giving
            the appearance of blue ink.Electronic ink uses less power than a
            PalmPilot,and the message remains displayed even after the power is
            turned off.

              The ultimate goal is for the electronic pages to look and feel
            like paper.However,for the foreseeable future,these new books are
            likely to be bulkier than paperback books.

              Electronic ink will have interactive qualities,although E Ink
            isn't sure people will be able to write with it for a while——they
            will mainly receive messages.Xerox Corp.is also working on a
            technology that could replace paper as portable,renewable reading
            matter.

              The Xerox technology is called Gyricon.It's composed of a silicon
            rubber compound with the thickness and flexilility of poster
            board.The Gyricon sheets have thousands of plastic balls suspended
            in oil.Each ball is black on one side and white on the other and
            together they act as pixels to display images.Images can be updated
            much the same way as with a monitor.The beads are embedded in a
            large sheet,with each microcapsule suspended in oil to allow the
            beads to rotate in their orbits,says Robert Sprague,manager of the
            document hardware lab and electronic paper projects at Xerox's Palo
            Alto Research Center.The paper could be powered by a matrix of
            transistors,such as those in laptop computer screens.Gyricon uses
            reflective light,like real paper,so it would use less electricity.

              A Gyricon book will eventually be connected with a wireless device
            that will enable a reader to download content from the Internet.

              Xerox will also make the Gyricon interactive,so a user could write
            on it and reuse it.

              (美国) 麻省坎布里奇市的E Ink公司是开发电子墨水和“纸”的先导,这种墨水和纸将替代今天我们所知道的报纸与书籍。

              利用电子墨水和双向无线通信有可能导致产生电子书籍 (当读者看完当前的书本时,可以选择新书刷新)
            或者产生能边读边用最新消息自我更新的报纸。

              由E
            Ink公司发明的电子墨水是一种透明的液体塑料,里面有微型封装块,封装块内含有在蓝色染料中的白色小片。微型封装块悬浮在像食用油那样
            的物质中。白色小片带负电荷,因而它们能对电刺激作出反应。

              据E Ink公司的副总裁兼总经理Russell
            Wilcox称,这种墨水可以涂在任何表面,从墙到计算机屏幕。然而,书写面看上去很像极薄的便携机显示屏,
            在正面有一透明的表面,在背面有线路。

              加上墨水表面上方的正电荷将使白色显现出来,使表面像一张纸那样白。如果正电荷加到下方,黑粒子将显现出来,给出蓝墨水的痕迹。

              电子墨水耗电比PalmPilot掌上型电脑还要少,甚至在断电之后信息仍能显示出来。

              这种电子页面的最终目标是看上去和感觉上都像纸。但在可预见到的未来,这些新型书很可能比真正纸的书体积更大。

              电子墨水具有交互的品性,虽然E Ink公司吃不准人们是否会用它写字—它们主要用来接收信息。

              施乐公司也在对一种能替代纸的技术——便携式、可刷新的读物,进行研究。

              施乐的这项技术叫Gyricon。它由硅胶化合物组成,具有像广告宣传牌那样的厚度和柔软性。Gyricon片有成千上万个悬浮在油中的塑料球。每个球一面是黑的,另一面是白的,两者共同起到显示图形的像素的作用。图形能以监示器那样的
            同样方法进行更新。

              施乐的Palo Alto研究中心文档硬件实验室和电子纸项目经理Robert
            Sprague称,小球被嵌在很大的片子中,每个微型封装块悬浮在油中,允许小球在自己的轨道中旋转。这种纸能由晶体管阵列供电,如便携机屏幕那样。Gyricon像真正的
            纸那样利用反射光,因而它用较少的电。

              Gyricon书最终将与无线设备相连,能使读者从因特网上下载内容。

              施乐也将使Gyricon具有交互功能,因而用户能在它上面写字和反复使用。
