+交换机
+
+**交换机（Switch）意为“开关”是一种用于电（光）信号转发的 网络设备** 。 它可以为接入交换机的任意两个 网络节点 提供独享的 电信号 通路。
+
+交换机的主要功能包括物理编址、网络拓扑结构、错误校验、帧序列以及流控。交换机还具备了一些新的功能，如对VLAN（虚拟局域网）的支持、对链路汇聚的支持
+
+路由器
+
+路由器（ Router ）是**连接两个或多个网络的硬件设备**，在网络间起网关的作用，是读取每一个 数据包 中的地址然后决定如何传送的专用智能性的 网络设备 。 它能够理解不同的协议，例如某个局域网使用的 以太网协议 ，因特网使用的 TCP/IP协议 。
+
+mac地址与ip地址
+
+MAC地址也叫物理地址、硬件地址，由网络设备制造商生产时烧录在网卡(Network lnterface Card)的[EPROM](https://baike.baidu.com/item/EPROM/1690813?fromModule=lemma_inlink)(一种闪存芯片，通常可以通过程序擦写)。[IP地址](https://baike.baidu.com/item/IP地址/150859?fromModule=lemma_inlink)与MAC地址在计算机里都是以[二进制](https://baike.baidu.com/item/二进制/361457?fromModule=lemma_inlink)表示的，IP地址是32位的，而MAC地址则是48位的 [3]。
+
+IP 地址是基于逻辑的，比较灵活，不受硬件的限制，也容易记忆。而 MAC地址在一定程度上与硬件一致，是基于物理的，能够标识具体的网络节点。这两种地址各有优点，使用时也因条件不同而采取不同的地址 [6]。
