Switch
A network switch is a device that forwards and filters OSI layer 2datagrams between ports based on the MAC addresses in the packets.This is distinct from a hub in that it onlyforwards the frames to the ports involved in the communication rather than allports connected.A switch breaks the collision domain but represents itself abroadcast domain.Switches make forwarding decisions of frames on the basis ofMAC addresses.Some switches are capable of routing based on Layer 3 addressingor additional logical levels; these are called multi-layer switches.

交换机
网络交换机是一个在数据包中的MAC地址端口之间转递和过滤OSI层（开放系统互连）的资料元的装置.它和集线器不同,它只向端口转递涉及通讯的帧,而不是连接所有的端口.交换机不是冲突域而是一个广播域.交换机基于MAC地址转递集线器的决策.有些交换机可以基于第三层的寻址或其他逻辑层次来选择路径.这些叫做多层交换机.
