打个比方,即便你开的是辆夏利,但在交通拥塞的情况下,它可以和法拉利跑车并驾齐驱,同样的道理或许也适合两项颇受注目的Internet接入技术——Cable调解器与DSL(考虑到纷繁的服务类别也称xDSL)。的确,我们对World Wide Wait的折磨可以说已经忍无可忍。网页慢悠悠地走下网来;图片一点一滴地在屏幕上渗透;若遇上Java applet,更是不知下载到何年何月。此情此景,如果Cable调解器与xDSL服务确能如预期般运作,即便花上每月50～189.95美元的费用(美国提供此类服务的运营商报价区间)也是物有所值,毕竟它能让你真正体会上网如飞的感觉;但问题是Cable与DSL能名符其实吗? 无庸置疑,Cable调解器与xDSL都具有很高的数据传输速率,但就Web应用而言,高数据传输速率似乎无关痛痒。原因有二:其一是你根本得不到允诺的速率,其二是影响Web应用的因素
For example, even if you drive a Xiali, it can keep pace with the Ferrari in case of traffic congestion, and the same goes for the two notable Internet access technologies - the Cable Modem and the DSL (Considering the variety of services also known as xDSL). Indeed, our torture of the World Wide Wait can no longer be tolerated. Going slowly to the web page; image bit by bit on the screen penetration; In case of Java applet, it is I do not know what year to download. In this scenario, if the Cable Modem and xDSL services do work as expected, it costs you $ 50- $ 189.95 per month (the carrier quotes for such services in the United States) Let you really feel the feeling of flying on the Internet; but the problem is the Cable and DSL can be true? Undoubtedly, Cable modem and xDSL have a high data transfer rate, but for Web applications, high data transfer Rate seems irrelevant. There are two reasons: one is that you simply can not get the promised rate and the other is the factor that affects the web application
