2024年3月1日 · Hubs are the hardware device that operates in the physical layer of the OSI model. It works with shared bandwidth and broadcasting. The hub can provide a high data transmission rate to different devices. It can detect collisions in the network and send the jamming signal to each port.

2025年2月7日 · Network devices are physical devices that allow hardware on a computer network to communicate and interact with each other. Network devices like hubs, repeaters, bridges, switches, routers, gateways, and brouter help manage and direct data flow in a network.

集线器(hub) 集线器就是将网线集中到一起的机器，也就是多台主机和设备的连接器。 集线器 的主要 功能 是对接收到的信号进行同步整形放大，以扩大 网络 的传输距离，是中继器的一种形式，区别在于 集线器 能够提供多端口服务，也称为多口中继器。

Ethernet HUB的基本工作原理是广播（broadcast）技术，也就是HUB从任何一个端口收到一个Ethernet包时，它都将此Ethernet包广播到所有其它端口，HUB中不记忆哪一个MAC地址挂在哪一个端口。

nic 就是 电脑网卡 hub 就是 集线器 你这个 光纤收发器 可能有些旧 现在 hub 基本上 淘汰了 其实，这2个接口 表示： 直接连 电脑的话，用 to nic接口； 要 连 网络连接设备的话，得用 to hub 接口。 祝你顺利

2022年6月14日 · A hub is also a hardware network device that connects multiple devices together. The hub repeats all the data packets it receives to all connected devices. Hubs are the simplest type of network device and are typically used for small and simple networks.

In this tutorial, you will learn about the concept of Network Devices (Repeater, Hub, Bridge, NIC, Switch, Router and Gateway). After reading this tutorial, you will get some basic idea about which device works on which layer, how it works, what are its advantages and disadvantages, etc.

2022年3月27日 · Network Interface Card (NIC) is a device that enables a computer to connect to a network and communicate. It provides hardware interface between a computer and a network. It can be a separate circuit board that is installed in a computer or a circuit already integrated with the motherboard.
