A joystick is a pointing device composed of a lever that moves in multiple directions to navigate a cursor or other graphical object on a computer screen. A keyboard is a typewriter— like device that allows the user to type in text and commands to the computer. Some keyboards have special function keys or integrated pointing devices, such as a trackball or touch-sensitive regions that let the user’s finger motions move an on-screen cursor.
An optical scanner uses light-sensing equipment to convert images such as a picture or text into electronic signals that can be manipulated by a computer. For example, a photograph can be scanned into a computer and then included in a text document created on that computer. The two most common scanner types are the flatbed scanner, which is similar to an office photocopier, and the hand-held scanner, which is passed manually across the image to be processed.

计算机专业英语Unit 2 Basic Knowledge of Computer

Coe 背景知识
❖ 计算机中采用的是二进制。我们生活和学习中遇到的数值、图形、图像、声音和视频等在计算机中均是用二进制数据来表示的。为什么计算机不用我们人类熟悉的十进制呢？这是与硬件物理特性密切相关的。

Information Representation
❖The computer uses electricity, not mechanical parts, for its data processing and storage.
❖To process real-world data in the computer, we need a way to represent the data in switches. Computers do this representation using a binary coding system.

这是由一个主句和四个从句组成的复杂长句，只有进行必要的语法分析，才能正确理解和翻译。现试译如下：除非相信那些机器造出的产品卖给消费者的价格足够支付所有成本，否则厂家是不会买那些机器的。节译：要不相信那些机器造出的产品售价够本，厂家是不会买的。后一句只用了24个字，比前句40个字节约用字40%，而对原句的基本内容无损。可见，只要吃透原文的结构和内涵，翻译时再在汉语上反复推敲提炼，复杂的英语长句，也是容易驾驭的。

Shift registers
A register capable of shifting its binary information in one or both directions is called a shift register.
The simplest possible shift register is one that uses only flip-flops.
The output of a given flip-flop is connected to the D input of the flip-flop at its right. The clock is common to all flip-flops. The serial input determines what goes into the leftmost position during the shift. The serial output is taken from the output of the rightmost flip-flop.
