23 Chapter 3 Number Systems and Boolean Algebra 3.1.6 Complements Today, the radix -1 complement is not used by itself; it is used as a step for finding the radix complement. The radix complement is used to represent negative numbers in modern computer systems.

如今，反码已不单独使用，而作为求补码的一个步骤使用，如今，反码已不单独使用，而作为求补码的一个步骤使用，补码是当代计算机系统表示负数的方法(反码用于早期的计算补码是当代计算机系统表示负数的方法反码用于早期的计算技术中)。

It has stronger I/O interface to connect with industrial process compared to the common computer and has basically substituted of the logical control of traditional relay and contact devices, thus become the basic installment in automation control system.

从广义上讲，PLC是一种计算机系统，比一般计算机具有更强的与工业过程相连接的输入输出接口，已基本取代了传统的继电器和接触器的逻辑控制，并成为自动化控制系统的基本装置。

This high-speed element is used as a "scratch pad" to temporarily store data and instructions that are likely to be retrieved many times during processing.Processing speed can thus be improved.Data may be transferred automatically between the buffer and primary storage so that the buffer is usually invisible to the application programmer.Once found only in large systems,cache memory is now avaliable in some of the tiny microprocessor chips used in personal computers.

该高速存储器可用作"便笺"，暂时存放那些在处理中很可能多次查询的数据和指令，这样可提高处理速度，由于数据在这个高速缓冲器和主存之间可自动传输，所以该告诉缓冲存储器对应用程序员来讲通常是不可见的，过去只在较大的计算机系统中才有的高速缓冲存储器，现在在一些用于个人计算机系统的很小的微处理器芯片中也采用了。
