Hub, the English name also known as the Hub, in the OSI model belongs to the data link layer. Cheap is its biggest advantage, but because the hub is a shared device, resulting in the heavy network, the efficiency becomes very low, so we can not see the hub in the medium and large network. Today's hubs generally use Ful

A hub is a connection device connected to multiple computers or other devices in a computer network. It is the smallest unit for centralized network management. A hub is a collection of branches, just like the trunk of a tree. Many types of networks rely on hubs to connect devices and distribute data to different network segments. The HUB is basically a shared de

A netizen does not know the cat and the router, the hub, the switch difference between them what is different? Computer knowledge Network for everyone to answer:
A cat has at least two ports: one to the telephone line and one to the RJ-45 port (network cable)
Routers are generally one port: RJ-45 but one to connect the network, a LAN
A router and a cat are not the same device
Routers, simple is composed of LAN, and also provide including packet fi
What are the differences between hub, switch, router, and modem ???
What types of networks are available (local area, wide area, and enterprise )?How should the above components be connected for each network type?

Hub ------- a hub is also called a hub
I. Overview
As its name implies, Hub is the activity center. In network terms, the Hub or Concentrator is a wiring point based on a star topology. Arcnet, 10Base-T, 10Base-F, and many other dedicated networks rely on hubs to connect each segment of cables and distribute data to each segment. The basic function of a hub is information distribution, which distribu
A repeater or hub cannot isolate a conflict domain and cannot isolate a broadcast domain, a bridge or a switch can only isolate a conflict domain from the broadcast domain, and the router can isolate the conflict domain and isolate the broadcast domain.ResolutionThe first thing to know is the conflict domain and broadcast domain, when a piece of network card send information, it is possible to conflict with another NIC network adapter is called the co
Multiple computers can be communicated via hubs in the Cisco Packet Tracer.Cisco Packet Tracer 6.2.0 One, add three computer equipment 1, in accordance with 1, 2 steps, 2 steps to execute three times, drag the PC to the way, you can also operate 2 steps when you hold down the CTRL key and then click Three blank places, to place three computers. Second, add the hub to the diagram 1, such as 1, 2, 3 steps, add a
Recently saw a lot of people asking about the switch, hub, router is what, function, what is the difference, the author on these questions to do some simple answers.
First of all said Hub, that is, hubs. Its role can be simply understood to connect some machines to form a local area network. A switch (also known as a switched hub) works roughly the same as a

Execute PS-A | grep khubd on the terminal, and the khubd process is displayed. This is the hub daemon process. Our device is inserted into the USB interface (whether it is inserted with the hub, after the sub-hub), the daemon detects the issue and then notifies the master controller of the interruption. The master controller then calls the
Which layer does the repeater, Hub, switch, bridge, and router correspond?
First, we need to analyze the functions of each device in detail:
I. RepeaterRepeater works on the first layer (Physical Layer) of OSI. Repeater is the simplest network interconnection device that connects two or more network segments in the same network. It mainly implements physical layer functions, transmits information by bit on the physical layer of the two network nodes t
After the hub is working properly, the master controller regularly queries whether the hub is interrupted. When a device is inserted or removed on the hub port, the hub sends a urb request to the master controller, that is, to tell the master controller about the change of the hub
1: first, these devices all work at different levels, such:
2: physical layer device:
Repeater or repeater: works on the physical layer. It is a simulated device used to connect two cable segments. The attenuation signal of one line is amplified, restored, and placed on another line, A repeater does not care about the concepts of frames, groups, and headers. It only understands the voltage value.
Hub: Working physical layer. The
