1.(P1) Computer science deals with the theoretical foundations of information and computation, together with

practical techniques for the implementation and application of these foundations, such as programming language theory, computational complexity theory, computer graphics and human-computer interaction.

计算机科学涉及信息和计算的理论基础，以及这些基础的实施和应用的实际技术，如编程语言理论，计算复杂性理论，计算机图形学和人机交互。

2.(P17) The most important piece of graphics hardware is the graphics card, which is the piece of equipment

that renders out all images and sends them to a display. There are two types of graphics cards: integrated and dedicated. An integrated graphics card, usually by Intel for use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large amount of video memory. A dedicated graphics card has its own RAM and Processor for generating its images, and does not slow down the computer. Dedicated graphics cards also have higher performance than integrated graphics cards. It is possible to have both dedicated and integrated graphics card, however once a dedicated graphics card is installed, the integrated card will no longer function until the dedicated card is removed.

最重要的一块图形硬件是显卡，是一件呈现出所有的图像，并将它们发送到一个显示器的设备。有两种类型的显卡：集成和专用。集成的显卡，通常由英特尔在他们的计算机上使用，被绑定到主板并且与中央处理器共享内存（随机存取存储器），减少了可用的内存总量。这对于使用大量视频内存的程序和应用来说是不可取的。

专用显卡有它自己的内存和处理器，用于生成它的图像，并且不会减慢计算机的速度。专用显卡也比集成显卡有更高的性能。有可能既有专门的也有集成的显卡，但是，一旦安装了专用显卡，集成显卡将不再起作用，直到专用显卡被移除。

3.(P18) Channel I/O requires the use of instructions that are specifically designed to perform（执行）I/O

operations. The I/O instructions address（处理）the channel or the channel and device; the channel asynchronously（异步的）accesses all other required addressing and control information. This is similar to DMA, but more flexible.

I/O通道需要使用专门设计来执行I/O操作的指令。I/O指令处理通道或通道和设备；通道异步访问所有其他所需的寻址和控制信息。这是类似于DMA，但更灵活。

4.(P19) 调制解调器是在模拟和数字信号之间进行转换的设备，它经常用于实现计算机之间通过电话线的互相通

信。如果两个调制解调器可同时互相发送数据，那么它们采用的就是全双工工作方式；如果一次只有一个调制解调器可以发送数据，那么它们采用的则是半双工工作方式。

Modem is a device that converts analog（模拟）signals to digital signals or conversely（相反地）. It is often used to communicate between computers via（渠道）telephone lines. If the two modems can send data to each other, they use full-duplex mode; if only one modem can transmit data, they use half-duplex mode.

6.(P21) We many have defined our last generation of computer and begun the era of generationless

computers. Even though computer manufactu rers talk of “fifth” and “sixth” generation computers, this talk is more a marketing play than a reflection of reality.
