    网络集线器

    网络集线器是指将多条以太网双绞线或光纤集合连接在同一段物理介质下的设备。

    网络集线器的工作原理

    • 网络集线器,属于数据通信系统中的基础设备,它和双绞线等传输介质一样,是一种不需任何软件支持或只需很少管理软件管理的硬件设备。
    • 网络集线器的主要功能是对接收到的信号进行再生整形放大,以扩大网络的传输距离,同时把所有节点集中在以它为中心的节点上。
    • 网络集线器工作于OSI(开放系统互联参考模型)参考模型第一层,即“物理层”。集线器与网卡、网线等传输介质一样,属于局域网中的基础设备,采用CSMA/CD(一种检测协议)访问方式。

    网络集线器的特点与优势

    • 应用广泛
    • 通信速率高
    • 资源共享能力强
    • 可持续发展潜力大

    网络集线器的应用

    • 自动化行业
    • 能源行业
    • 机械和机器人行业
    • 运输业
