由于微型机局部网络具有结构简单、灵活、低成本、较高的可靠性等优点,因此近几年取得了飞速的发展,它被广泛用于机关、学校、银行、医院、旅馆等部门。本文先概括地对微型机局部网络作个介绍,然后具体介绍一下目前最常见的两个微型机局部网络——OMNINET 和 ETHERNET。一、微型机局部网络概述微型机局部网络在结构上有下述特点:·网络中各工作站地位均等,这一点不同于远程计算机网。后者必须有一个或几个硬件资源丰富的大型机或中型机任主机,供其他站共享其资源。这一点使局部网价格低,连接灵活。·各工作站都是独立的单元,这一点不同于分时 Due to the advantages of simple structure, flexibility, low cost and high reliability, the local network of microcomputers has achieved rapid development in recent years. It is widely used in offices, schools, banks, hospitals, hotels and other departments. This article first general introduction to the local area network of microcomputers, and then introduce the two most common local network of microcomputers --OMNINET and ETHERNET. First, an overview of the local network of microcomputers Local network of minicomputers in the structure has the following characteristics: * Workstation in the network equal status, which is different from the remote computer network. The latter must have one or more hardware-resourced mainframes or midsize hosts for other sites to share their resources. This makes the local network low price, flexible connection. · Each workstation is a separate unit, which is different from the timeshare
