active hub的意思|示意

Active hubs are devices used to connect computers or other networking devices together on the same network. In computer networking, an active hub is a device that has at least one transmitter and several receivers. The active hub allows the broadcasting of data over its ports so that a single transmission may be received by multiple devices.

Active hubs can be found in many different types of networks. They are used within a local area network (LAN) to connect multiple computers together, and within a wide area network (WAN) to join multiple nodes together. In addition, many routers and switches are actually active hubs that allow for the transmission of traffic in several directions.

Active hubs are usually wired, but wireless active hubs have become quite popular in recent years. Typically, these wireless hubs are used to connect laptops and other portable devices to a network. They use technologies such as Wi-Fi, Bluetooth, and infrared to transmit data.

Active hubs can be either managed or unmanaged. Unmanaged hubs simply pass the data they receive to all connected devices, while managed hubs have advanced features such as port monitoring, packet filtering, and bandwidth control.

In conclusion, active hubs are devices that are used to connect computers and other devices to a network, either wired or wireless. They may be either managed or unmanaged, depending on their features and capabilities. Active hubs are important components of both local area and wide area networks, and their importance is sure to grow as wireless and mobile networks become more popular.
