DVI连接有两种主要类型： • DVI-数字（DVI-D）是纯数字格式。它需要带有DVI-D 连接的视频适配器和带DVI-D 输入的显示器。该连接器 有三行的24针/孔以及一个用于双连接的接地槽。对于单 连接，连接器有8针/孔。 • DVI-集成（DVI-I）既支持数字传输也支持模拟传输。 这使你可以选择连接到接收数字输入或模拟输入的显示 器。除了连接器上的针/孔用于数字支持，DVI-I连接器 上有4个附加的针/孔传输模拟信号。 如果你购买的显示器只有一个DVI（数字）连接，确保 有带DVI-D或DVI-I连接的视频适配器。如果你的视频适 配器只有一个模拟（VGA）连接，找一个支持模拟格式 的显示器。

简单地说，彩色位深度制指描述单个像素颜色所用的位 数。位深度决定了一次可以显示的颜色数。下图表明了 不同位深度可以产生的颜色数。 注意，表中最后一项是32位。这是数字视频、动画和视 频游戏所用的特殊图像模式，用来实现特定效果。从本 质上说，24位于彩色，另外8位用于表现物体和图像中半 透明的各层。今天几乎每个显示器都可以使用标准的 VGA连接处理24位彩色。 要建立单个的彩色像素，LCD 显示使用带有红、绿、蓝 滤光器的三个子像素。通过对电压的仔细控制和调节， 每个子像素有256级以上灰度。这些子像素的组合可以产 生一个具有一千六百八十万种颜色的调色板（256级的红 x256级的绿x256级的蓝）。

1. 标准和分辨率 分辨率指屏幕上包含的单个彩色点（所谓的像素）数目。 可以通过指定水平轴（行）的像素数和垂直轴（列）的 像素数来表示分辨率，如800X600。分辨率受到多种因 素的影响，包括屏幕大小。 随着显示器大小的逐年增加，显示标准和分辨率已经改 变。另外，一些厂家为了看DVD电影推出了宽屏幕显示 器。 （表格略） 除了屏幕尺寸外，显示标准和分辨率还与纵横比有关。 下面我们将讨论什么是纵横比以及如何度量屏幕尺寸。

First-generation computers of historic significance, such as UNIVAC, introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV(Translate the following passage from English into Chinese.A computer system includes a computer, peripheral(外围的)devices, and software.

Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task.

西电物联网英语(第二版)(张强华)参考答案
Unit 1 Text AExercisesI. Answer the following questions according to the text.1. The Internet of Things refers to uniquely identifiable objects (things) and their virtual representations in an Internet-like structure. The term Internet of Things was first used by Kevin Ashton in 1999.2. It stands for Radio-frequency identification. It is often seen as a prerequisite for the Internet of Things.3. Casagras is a global network infrastructure, linking physical and virtual objects through the exploitation of data capture and communication capabilities. This infrastructure includes existing and evolving Internet and network developments.4. In the IoT, physical and virtual ‘things’ have identities, physical attributes, and virtual personalities.5. The original idea of the Auto-ID Center is based on RFID-tags and unique identification through the Electronic Product Code.6. The next generation of Internet applications which use Internet Protocol Version 6 would be able to communicate with devices attached to virtually all human-made objects because of the extremely large address space of IPv6.7. In the future the Internet of Things may be a nondeterministic and open network in which auto-organized or intelligent entities (Web services, SOA components), virtual objects will be interoperable and able to act independently (pursuing their own objectives or shared ones) depending on the context, circumstances or environments. 8. Embedded intelligence can be more clearly defined as: leveraging the capacity to collect and analyze the digital traces left by people when interacting with widely deployed smart things to discover the knowledge about human life, environmentinteraction, as well as social connection/behavior.9. In an Internet of Things, the precise geographic location of a thing — and also the precise geographic dimensions of a thing — will be critical.10. Currently, Internet of Things frameworks seem to focus on real time data logging solutions like Pachube: offering some basis to work with many "things" and have them interact. Future developments might lead to specific software development environments to create the software to work with the hardware used in the Internet of Things.II.
