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

I have a machine in my house (with win98se) and a notebook (with XP ). I want to use hub because I want to access the Internet with my husband (I bought a hub because I was not quite clear about the situation .) internet sharing. but I don't know how to set it. Can you help me teach me. thank
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

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
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
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
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
useful results from it!Azure is a Microsoft-provided cloud service platform that offers a wide range of applications such as databases, virtual machines, application services, machine learning, data flow analysis, media and CDN Services, Big Data solutions, and many other applications including IoT hub. The large number of applications it provides itself is a good reason to use Azure services, but Microsoft is further demonstrating that its scenario

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
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.

How to get real news through Gmail?
I usually keep using Gmail in my browser, and I also use the Gtalk client in Gmail. In addition, I have now become a fan of Twitter. Twitter is a micro-blogging tool that you can control through Gtalk or other IM clients.
On Twitter, some people get information from the BBC and CNN and input it to Twitter. Therefore, if you keep using Gmail, Twitter wi
can provide high-speed connection ports that support fast Ethernet or FDDI. These ports are used to connect other vswitches in the network or provide additional bandwidth for key servers with high bandwidth usage. It is a network device and has a part of the router function. It can decide where the received data is sent, and its speed is faster than that of the router.

Many small partners on Azure have the need for vnet connectivity. Vnet Gateway is now available in Azure in a cross-region scenario to enable interoperability via the S2S, which can be achieved through vnet peering in the same region. The above is a simple two vnet interoperability scenario, when there are more than one vnet to achieve the interoperability between any and any, through this 22 interconnection method workload and complexity is significantly too high.
