微型计算机又称个人电脑或PC机,在我国来说主要是IBM兼容机,即286、386、486等微机。 要弄清各种型号之间的差别,应首先对计算机的核心——中央处理单元(即CPU)的性能有一简单的了解。PC及其兼容机都采用Intel公司设计的CPU,根据CPU型号的不同,微机的类型也各异。Intel公司先后开发了4004、8088、8086、80286、80386、80486等CPU,性能逐渐提高。例如:Intel 8088是准16位CPU,即计算机在一次操作中能处理二进制16位字长的数,但外部数据通路为8位;8086和80286是16位CPU;80386和80486是32位CPU。基于8088的
Microcomputer also known as personal computer or PC, in my country is mainly IBM compatible machine, that is, 286,386,486 and other microcomputer. To understand the differences between the various models, first of all have a simple understanding of the performance of the core of the computer, the central processing unit (CPU). PC and compatible machines are designed by Intel CPU, according to the different CPU models, different types of computers. Intel has developed 4004,8088,8086,80286,80386,80486 CPU, the performance gradually increased. For example, the Intel 8088 is a quasi-16-bit CPU that can handle a binary 16-bit word count in one operation, but the external data path is 8 bits; the 8086 and 80286 are 16-bit CPUs; and the 80386 and 80486 are 32-bit CPUs. Based on the 8088’s
