How to build a LAN with a hub, and what is the difference between a hub and a switch in building a L

Hello, it is difficult to see the hub on the market now, but its role is similar to that of the switch, the specific method is: all four computers are connected with network cables and hubs, the IP address of each computer is set to any number in between, and the working group of the computer is set to a unified name or default, so far, the LAN is connected. But this alone will not be able to access the Internet.

You have to add a router to get online.

...Plug it in directly, set the IP to the same network segment, for example, set up the firewall of each machine (including anti-virus software, it is best to turn it off), and you should be able to achieve the sharing and online games you said.

If not, one machine can create a workgroup and other machines can join. The creation method is to open the online neighbor to know.

Who still uses a hub these days? The days of hub networking are long gone.

Basically, they all use switches and routes.

If you want to use a hub, you have to find a machine to use as a server. The server is open, so you can access the Internet... Of course, if there is a switch upstream of the hub, then it is not necessary. ）

And the hub is bandwidth-splitting.

Buy a switch or router. It's not expensive.

Hub, the traditional hub can be regarded as a multi-port repeater, in the first layer of the OSI model - the physical layer, requiring the data rate at both ends of the port to be consistent, the data frame to be consistent, the communication protocol to be consistent, this hub can play a role in connecting the network, extending the ability of the network, can form a huge star network from them. But it's shared**, and the total bandwidth is limited, and the bandwidth allocated to each port is even more limited. Compared with switches, the data transmission rate of the hub is limited, and if there are many sites, it will cause a rapid decline in system performance.

Switch, the switch is in the second layer of the OSI model - the data link layer, the data transmission principle of the switch is different from the hub, it uses the matrix switching channel to transmit data, each data channel has independent bandwidth, although a port can only have one channel at a time, but on the whole, the switch is opened at the same time with multiple switching channels, therefore, the data transmission performance of the switch is much higher than that of the hub. In addition, because switching devices are no longer confined to the collision domain, switches have the greatest advantage over hubs on extended networks. Switches are smarter.

With the development of network technology, one network technology cannot easily disappear, nor can one device replace all other devices, all kinds of devices are constantly evolving. In recent years, there have been many types of hubs, such as smart hubs, stackable hubs, switched hubs, and so on.

The performance of the hub has been expanded. For example, a Fibre Channel hub is a Fibre Channel arbitrated loop topology that enhances the connectivity of servers and storage devices.

Similar to Ethernet hubs, Fibre Channel hubs are at the heart of an FC-AL topology, allowing loops to be centrally monitored and managed. By using a hub, multiple can add and detach network devices in the loop without interrupting the loop's operation.

Switched hubs, a recent addition to the Fibre Channel hub family, bridge the gap between hubs and switches. The hubs are easy to manage, and the ports on the switched hubs are all dedicated, with maximum bandwidth for each port.

Therefore, whether to use a hub or a switch in the network can be considered from the following aspects:

Bandwidth Fibre Channel hubs are similar to Ethernet hubs in that all ports are capable of acquiring data emitted by other ports. This way of working often leads to bandwidth congestion and sometimes security issues. However, the ports of the switch are completely independent, and each port can simultaneously support the maximum bandwidth limit of the topology used.

Security Security may be a factor to consider when deciding whether to use a hub or a switch. The use of high-performance switches can easily logically segment the network, build a virtual LAN, improve network security, and improve the management level of the network. Whereas hubs do not have this capability.

On the other hand, the switch is generally more expensive for hubs with the same number of ports, like some small networks, you can still consider using hubs, but it is a trend for switches to replace hubs.

The easiest way is to connect to the HUB under the LAN port of the router to increase the number of LAN connections. The hub does not have a gateway function, you can use a router relatively easily, if you build a gateway server by yourself. If you have any questions, ask me again.

Hubs are widely used, not only in local area networks, enterprise networks, campus networks, but also in wide area networks. Most small LANs use a star LAN with a twisted pair of RJ-45 connectors, which often involves hubs. The function of a hub is to allocate bandwidth and connect independent computers in the LAN to communicate with each other, as shown in Figure 2-12.

If you have all the hardware, you have no problem creating a local area network. Make sure that each computer has a network card, then buy the corresponding number of network cables, and just connect them.

If you want to surf the Internet, you need to install software or use the following methods:

1. Make sure your cat belt does not have a routing function. If you don't bring it, please buy a router.

Ethernet cables are not available. As many computers as there are, you need to have the right amount of network cables. Prepare an extra one, and the cat should be connected to the router (or hub).

Here's how: (Router Method).

The first step is to make a good network cable, and you need to use professional tools. (Please go to the computer shop and ask him to pick it up when you buy a network cable).

The second step is to connect the cat to the router, and then connect the computer to the router separately (within 4 units).

Step 3: Set up your router and computer. Call it a day.

The above requires a certain amount of computer network knowledge. If you share broadband Internet access privately, it is recommended that you ask someone from a computer company to do it for you.

Or mine** go up and have a look.

It seems that you are mistaken, and you need a router to use it this way.

First, set the IP addresses of the two PCs to and.

Workgroup setup.

Computers in a LAN should belong to the same workgroup in order to access each other.

a.Right-click the My Computer icon and choose the Properties command from the shortcut menu to open the System Properties dialog box.

b.Click the Network Identity tab, and then click the Properties button to open the Identity Change dialog box. Click the Workgroup option in the Affiliations option group and enter the name of the workgroup in the text box below (e.g. hy, note that the workgroup name must be set to one for all PCs).

Follow the same method to set up another computer.

Sharing of computer resources.

In Windows XP LAN, every software and hardware resource in the computer is called a network resource, and users can share software and hardware resources, and the shared resources can be accessed by other computers in the network. Let's take folder sharing as an example. Hardware resources are shared similarly.

a.Right-click the folder to be shared and choose the Share command from the shortcut menu to open the Share Properties dialog box.

b.Click on the "Share this folder" option to set it up in detail in the following options:

Share Name: The name of the shared folder.

User Limit: This setting limits the maximum number of users who can use the shared folder.

Sharing permission setting: This setting makes the folder only available to users who have access. To set sharing permissions, click the Permissions button to open the permissions dialog box.

In this dialog box all the usernames that have access will be displayed, and everyone refers to all network users. In the "Permissions for everyone" list, the current sharing permissions are listed, including full control, change, read permissions, etc., click "Allow" or "Deny" to set them. You can also click the Add button to add other users or groups to set sharing permissions for the folder.

There should be no problem setting it up as above, good luck!

Common groups, choose different IPs and then it should become.

Connect to the hub, and then set the IP address to the same network segment, and the gateway does not need to be adopted.

The hub has four ports, so connect:

Take the router with four LAN ports as an example, connect the hub entrance to one of the LAN ports of the router, which will occupy a LAN port, if there is a wireless connection, then the occupied LAN port is replaced by a wireless connection, if not, then use a wire to connect back to the hub, on the line.

All the machines are set to auto IP, assigned by the router, and it's done.

You should all belong to the same LAN and should not be used for any adjustments. Build a house in Warcraft, it should be visible.

each other's. (Pay attention to the settings of the firewall).

There should be a switch in your dorm building.

If you only use the LAN, you can use the router, so your computers are connected to the hub, and if you all have your own hub, connect the 2 hub network cables.

The premise is that it is best to manually assign IP to each computer; Gateway, the gateway must be consistent, such as or.

Yes, one hub is enough, one end of a network cable is connected to the total interface of the network cable, and the other end is connected to the hub, and each computer is connected to the hub Each computer is configured with the IP address and subnet mask — 6 computers Subnet mask Fill in these 2 items If the hub port does not have 6, use a wire from the hub to the router to OK.
