总线是微机系统中的一个重要组成部分,它为系统所有的硬设备提供接口。总线的特征包括它的结构、位数及带宽。总线位数:是指在计算机中一次可传送的二进制编码位数。总线带宽:指总线传递数据的速率。选购微机时,何种类型的总线结构是一个重要的参考指标,下面简单介绍微机市场上最常见的几种总线结构。 ISA总线称为工业标准总线。由IBM PC—AT引入,即市场最常见的AT标准总线,总位数为16位。 EISA总线称为增强型工业标准总线。由COM-
The bus is an important part of a microcomputer system that provides an interface to all the hardware of the system. The characteristics of the bus include its structure, number of bits and bandwidth. Bus bits: refers to the computer can be sent once the binary code bits. Bus bandwidth: refers to the bus transfer data rate. When choosing a computer, what type of bus structure is an important reference index, the following brief introduction to the computer market, the most common types of bus structure. The ISA bus is called the industry standard bus. Introduced by IBM PC-AT, the most common AT standard bus on the market, with a total of 16 bits. The EISA bus is called the Enhanced Industry Standard Bus. By COM-
