Bus Systems Supporting Multiple Peripherals
5 / 30

As the number of potential peripherals grew, using an expansion card for every peripheral became increasingly impossible. This has led to the introduction of bus systems designed specifically to support multiple peripherals. Common examples are the SATA ports in modern computers, which allow a number of hard drives to be connected without the need for a card. However, these high-performance systems are generally too expensive to implement in low-end devices, like a mouse. This has led to the parallel development of a number of low-performance bus systems for these solutions, the most common example being Universal Serial Bus. All such examples may be referred to as peripheral buses, although this terminology is not universal.uEh0U1Yfmh Notes: 1. Serial ATA (SATA) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.IAg9qLsgBX 2. Universal Serial Bus USB 支持多种外接设备的总线系统 随着外接设备数量的不断增加，想用扩展卡来应付每一种外围设备越来越不现实 了，这就产生了设计专门支持多种外接设备的总线系统。通常的例子就是现代计算机 上的 SATA 接口，这就允许很多硬盘驱动器不需要卡就可以同计算机连接起来。但是 把这些高性能系统用于低端设备，如鼠标等就很不合算。这就导致同时开发很多低性 能的总线系统解决方案，最常见的例子就是 UBS 接口。所有这些例子都可以称作外接 设备总线，尽管这个术语还没有普遍通用。WwghWvVhPE

typically removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g. As of September 2011, drives of up to 256 gigabytes (GB) are available. Storage capacities as large as 2 terabytes are planned, with steady improvements in size and price per capacity expected. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and a 10 year shelf storage time.bR9C6TJscw USB flash drives are often used for the same purposes for which floppy disks or CD-ROMs were used, i.e., for storage, back-up and transfer of computer files. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts. Until about 2005, most desktop and laptop computers were supplied with floppy disk drives, but floppy disk drives have been abandoned in favor of USB ports.pN9LBDdtrd Notes GB: gigabyte 吉字节 109 字节； terabyte TB 太字节，1012 字节 USB 闪驱 USB 闪驱是一种数据存储设备，它包含带有一个集成的通用串行总线（USB ）接 口 。USB 闪驱通常可以移动并可以重写，其尺寸要比软盘小得多，大多数的重量不到 30 克。从 2011 年 9 月始，市场就出现 256 GB 的 U 盘。2 太字节的 U 盘在筹划之中， 估计 U 盘大小会更加合理，价格也更合适。有的 U 盘允许写/擦 10 万个循环，这取决 于存储芯片的型号，储存寿命可以达到 10 年时间。DJ8T7nHuGT USB 闪驱与软盘或 CD-ROM 的目的相同，就是为了计算机文件的存储、备份和转 移。因为它们没有移动部件，所以体积更小，速度更快，拥有数千倍的容量，更加持

With digital copying, the copier effectively consists of an integrated scanner and laser printer. This design has several advantages, such as automatic image quality enhancement and the ability to "build jobs" (that is, to scan page images independently of the process of printing them). Some digital copiers can function as high-speed scanners; such models typically offer the ability to send documents via email or to make them available on file servers.AHP35hB02d

A great advantage of digital copier technology is "automatic digital collation." For example, when copying a set of 20 pages 20 times, a digital copier scans each page only once, then uses the stored information to produce 20 sets. In an analog copier, either each page is scanned 20 times (a total of 400 scans), making one set at a time, or 20 separate output trays are used for the 20 sets.NDOcB141gT Notes : scanner 扫描仪 盘，文件盘 1zOk7Ly2vA 复印机的数字技术 新的复印机越来越趋向于采用数字技术替代老的模拟技术。数字复印机有效地把 扫描仪和激光打印机整合在一起，这种设计拥有数个优势，譬如自动图形质量提高， 自动工作的能 fuNsDv23Kh 力 （扫描和打印互不干涉） 。有些数字复印机如同一个高速扫描仪，这样的型号通 常具有通过 email 发送文件的能力，或者给文件服务器提供文件。tqMB9ew4YX 数字复印机的最大优点在于它可以“自动数字校验”。例如当要复印 20 页，每页 复印 20 份的时候，数字复印机只需每一页扫描一次，然后使用储存的信息复印 20 份。 如果是模拟复印机，要么每一页都要扫描 20 次 （一共要扫描 400 次） ，一次复印一份； 要么每页复印 20 份，20 页分别放在 20 个输出托盘中。HmMJFY05dE [Ex.6] 1.

Smartphone To really understand what a smartphone is (and is not), we should start with a history lesson. In the beginning, there were cell phones and personal digital assistants (or PDAs). Cell phones were used for making calls--and not much else--while PDAs, like the Palm Pilot, were used as personal, portable organizers. A PDA could store your contact info and a to-do list, and could sync with your computer.RQxPvY3tFs Eventually, PDAs gained wireless connectivity and were able to send and receive e-mail. Cell phones, meanwhile, gained messaging capabilities, too. PDAs then added cellular phone features, while cell phones added more PDA-like (and even computer-like) features. The result was the smartphone.5MxX1IxuU9 智能手机 要真正理解什么是智能手机，什么不是智能手机，我们应该从了解历史开始。起 初人们使用手机和个人数字助理。手机只是用来打电话，而数字助理，如掌上电脑， 是个人便携式的记事本。一台个人数字助理能储存你的联系信息以及将要处理的事 情，可以和电脑同步。jIw5xs0v9P 最终，个人数字助理开始了无线连接，能够发送和接收电子邮件，而手机也具备 了获取信息的能力。个人数字助理添加手机功能，手机也增添个人数字助理 （甚至计算 机）的特性，其结果就是智能手机。xEve2buwnw [Ex. 6] 1.

第9单元电子商务 第一部分听力和对话 对话：使用在线支付服务保护消费者的隐私 (Henry非常兴奋地在一家网上书店中发现了自己期待已久的图书，但是当得知系统要 求通过账号支付时，他犹豫了。) Henry: 最近互联网上信用卡账号的公然欺骗无疑为我们敲响了警钟。在进行在线交易时，我们并不知道要把自己的信用卡账号告诉谁。 Mark: 也许你可以使用第三方支付服务来保证在线支付更简单、更安全。 Henry: 什么是第三方支付服务？ Sophie: 简单地说，在使用第三方支付服务时，你可以把自己的资金转移到一个在线账号中，然后从那个账号中进行支付。这样就不用把自己的真实信用卡或银号账户信息暴露在网络上了。 Henry: 这种方法听起来更安全。有哪些第三方支付服务可以方便地使用？ Mark:在美国最受欢迎的服务是eBay公司掌控的PayPal,但也有一些其他的服务，如https://www.sodocs.net/doc/129730861.html, Payment等。以最简单的支付为例，例如在线拍卖或简单的网站销售，销售商只需要向买家提供他们的E-mail地址，而买家向销售商的PayPal账号进行适当的支付。Henry: 我明白了。 Sophie: 做出选择之后，建议你留意选择更加安全服务的一些细节。 Henry: 什么是更加安全服务的一些细节呢？ Sophie: 首先，阅读隐私政策，并确保自己同意其中的条款。如果不同意，可以继续选择其他的安全服务。此外，确认网站符合权威部门规定的特定的标准（查验同意的盖章）。这些的确都是非常重要但是有时被用户忽略的步骤。 Mark: 当使用第三方支付服务时，Henry,请记住千万不要回复来自第三方支付服务机构发送的要求确认如密码或其他私人身份识别信息等与账号细节相关的电子邮件。这些邮件很可能是身份盗窃骗局，如网络钓鱼。 Henry: 那么，怎样才能更安全地确认或处理我的账号细节呢？ Sophie: 如果需要确认或更新账号信息或者修改密码，我建议你可通过个人书签或者在浏览器中直接输入支付服务网站的URL来访问相应的网站。 Henry: 如何进一步确认卖家能够提供有效的支付服务？ Mark: 你可以通过查看卖家在几个月或更长的时间内是否为支付服务机构的有效成员来确定。有些网站还允许用户查看卖家的评价，虽然这些评价并不能作为保证，但是却是非常有用的信息。 Sophie: 切记，Henry,不要用自己的账号把资金转移到一个你不认识的人的账号里。这可能是一种高级的资金诈骗。还有，当你要购买一些诸如珠宝或者计算机等昂贵的物品时，尤其是在节假日或者商铺中售出的物品时，需要多加小心。 Henry: 好的。现在我对进行安全在线支付更加有信心了。非常感谢你们的见议。 练习

大学实用计算机英语教程翻译-吕云翔-Unit 5

Unit 5 Section A Software Design （软件设计） Design is defined in [IEEE610.12-90] as both “the process of defining the architecture, components, interfaces, and other characteristics of a system or component ” and “the result of that process.” Viewed as a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software ’s internal structure that will serve as the basis for its construction. More precisely, a software design (the result) must describe the software architecture -- that is how software is decomposed and organized into components -- and the interfaces between those components. It must also describe the components at a level of detail that enable their construction. Software design plays an important role in developing software: it allows software engineers to produce various models that form a kind of blueprint of the solution to be implemented. We can analyze and evaluate these models to determine whether or not they will allow us to fulfill the various requirements. We can also examine and evaluate various alternative solutions and trade-offs . Finally, we can use the resulting models to plan the subsequent development activities, in addition to using them as input and the starting point of construction and testing. In a standard listing of software life cycle processed such as IEEE/EIA 12207 Software Life Cycle Processes [IEEE 12207.0-96], software design consists of two activities that fit between software requirements analysis and software construction: Software architectural design (sometimes called top level design): describing software ’s top-level structure and organization and identifying the various components. Software detailed design: describing each component sufficiently to allow for its construction.

D Original Roadrunner On the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux. Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can do in one day. IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.
