What is a network hub
A network hub is a network device that connects various network nodes, for example, in an Ethernet network, in a star configuration. In the OSI (Open Systems Interconnection) reference model, hubs are classified as level 1 devices operating at the physical layer. Their main task is to interconnect multiple computers and forward received data immediately. Hubs are usually made of plastic, run on external electricity, and contain 4 to 16 ports, i.e. physical connections. Their maximum bandwidth is usually 10/100 Mbit per second.v

An Ethernet hub is a device that connects multiple Ethernet twisted pair cables or optical fibers to the same physical medium. A hub operates at the physical layer of the OSI model[1], allowing connected devices to work on the same network segment. A hub has multiple I/O ports, and a signal entering from any port will appear from the other ports. [2] Repeater hubs also participate in collision detection, forwarding congestion signals to all ports when a collision is detected. In addition to standard 8P8C ("RJ45") connectors, some hubs also support BNC or AUI (Attachment Unit Interface) to connect to traditional 10BASE2 or 10BASE5 networks.
Since the hub will regenerate or amplify any digital signals it receives and then submit them from all ports of the hub, there is a high chance of collision between signals, and the signals may also be eavesdropped. This also means that all devices connected to the hub belong to the same collision domain and broadcast domain, so most hubs have been replaced by switches.

集线器（Ethernet hub）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。集线器是运作在OSI模型中的物理层[1]，可以让其链接的设备工作在同一网段。集线器上有多个I/O端口，信号从任意一个端口进入后，会从其他端口出现。[2]中继器（Repeater hub）也会参与冲突检测（collision detection），在检测到冲突时向所有端口转发拥塞信号。除了标准的8P8C（“RJ45”）水晶头，一些集线器也支持BNC或AUI（附加单元接口）来连接传统10BASE2或10BASE5网络。
由于集线器会把收到的任何数字信号，经过再生或放大，再从集线器的所有端口提交，这会造成信号之间碰撞的机会很大，而且信号也可能被窃听，并且这代表所有连到集线器的设备，都是属于同一个碰撞网域以及广播网域，因此大部分集线器已被交换机取代。

A network hub receives data and then sends it intact to all connected devices (hosts). All ports of a hub run at the same speed and are located in a collision domain. Unlike other network devices, a hub does not offer the option to control or exclude only a single receiver. This means that during transmission, all data packets are always forwarded to all computers. This means that even devices that the data is not intended for receive it. Since all hosts are occupied in this way, other devices cannot send any data on their own during this time. Instead, concurrent requests are processed one after the other.

网络集线器接收数据，然后将其完整发送到所有连接的设备（主机）。集线器的所有端口都以相同的速度运行，并且位于冲突域中。与其他网络设备不同，集线器不提供仅控制或排除单个接收器的选项。这意味着在传输过程中，所有数据包始终转发到所有计算机。这意味着，即使数据不打算用于的设备也会接收数据。由于所有主机都以这种方式被占用，因此其他设备在此期间无法自行发送任何数据。相反，并发请求将一个接一个地处理。
