A hub is a hardware network infrastructure device and refers to a device in which multiple Ethernet twisted pair sets are linked in the same physical medium. The main function of the hub is to shape the received signal and amplify it to increase the transmission distance of the network. Does the user know about hub definitions? Today Xiao Bian came to the specific introduction of the definition of the hub, I hope to help everyone. A daily storage box is a type of storage container that is often used to organize and store items that are used on a daily basis. Packaging Box.These boxes can come in a variety of sizes, shapes, and materials, and often have compartments or sections for different types of items.Storage Bin. They are often used in offices, homes, and schools to keep desks or workspaces tidy and organized. Some common items that might be stored in a daily storage box include stationery, makeup, jewelry, craft supplies, and small tools.Plastic Storage Bin Plastic Storage Box,Daily Storage Box,Storage Bin,Plastic Storage Bin Kunshan Muchun Electric Co., LTD , https://www.muchunmanufacture.com
Hub (HUB) belongs to the basic equipment in the data communication system. Like a transmission medium such as a twisted pair, it is a hardware device that does not require any software support or requires little management software management. It is widely used in various situations. The hub works in a local area network (LAN) environment and, like a network card, is applied to the first layer of the OSI reference model, and is therefore also referred to as a physical layer device. The interior of the hub is interconnected by electrical appliances. When the environment for maintaining the LAN is a logical bus or a ring structure, a physical star or tree network structure can be established by using a hub. In this regard, the hub functions as a multi-port repeater. In fact, the hub is actually a kind of repeater. The only difference is that the hub can provide more port services, so the hub is also called a multi-port repeater.
The common hub external board structure is very simple. For example, D-Link's simplest 10BASE-T Ethernet Hub is a rectangular parallelepiped with AC power outlets and switches on the back, an AUI interface, and a BNC interface. A 17-line RJ-45 interface is distributed across most of the front. On the right side of the front there are LED interface indicators and LED status indicators for each RJ-45 connector. High-end hubs look no different from modern routers or switch routers. Especially the modern two-speed self-adaptive Ethernet hubs, due to the universal built-in switch modules that can realize inter-communication between the internal 10Mb/s and 100Mb/s network segments, make these hubs completely available in the network segment where the hub is a node. The exchange of communication between the various nodes is realized, and sometimes people also call such a switching hub simply as a switch, which makes it difficult for users who use the hub for the first time to correctly identify them. However, judging the hub according to the type of backplane interface is a relatively simple method.
