一、以太网概述由于计算机的发展,特别是微处理机的大量生产及价格的不断下降,计算机的使用形式正在发生变化。研究所、工厂、学校,机关等微处理机的大量采用,要求形成一个属于单一组织所有的本地计算机网络,以共享数据库、大容量高速存储器、用于检查文件的文件、高速矩阵处理程序之类的高级软、硬件资源。软件的共用还可以使各微型机系统的程序和数据相互通融使用,对大型软件的开发也非常需要。本地计算机网还可以用于情报交换、检索及远距离故障诊断等。
I. Overview of Ethernet Due to the development of computers, especially the mass production of microprocessors and the declining prices, the usage patterns of computers are changing. The widespread adoption of microprocessors at institutes, factories, schools, agencies, etc. requires the formation of a local computer network belonging to a single organization to share databases, high-speed memory, files for examining documents, high-speed matrix processing programs and the like Advanced software and hardware resources. The sharing of software can also make the programs and data of each microcomputer system interoperate with each other, and it is also very necessary for the development of large-scale software. Local computer network can also be used for information exchange, retrieval and remote fault diagnosis.
