What is the difference between a hub and a router? The master will explain! Hurry!!!!

Routers can split broadcast domains.

It is also possible to divide the conflict domain.

Hubs, on the other hand, cannot.

If you are building a small LAN (about four machines).

It is possible to use a hub (requires a correct design and implementation of the network) if there are many machines in the LAN.

A switch should be used.

Routers are more expensive due to **.

If it is used personally, it is not a calculation.

Switches and hubs can be connected with ordinary network cables.

It's easy to understand when you look at it.

Of course, the router is better!

The hub can only form a local area network, which means that only a few computers can be connected, and if you want to share the Internet, you need to set up the host, and only when the host is turned on, other computers can share the Internet.

The router can not only form a local area network, but also connect several computers, and if you share the Internet, you don't need to set up a host, and you can access the Internet whenever you turn on the computer.

As far as I know, the router is the hub with several features, such as automatic adjustment of resource allocation, automatic dialing The router will be a little more expensive About twice as much as the hub

The hub is actually a bus topology, that is, a shared channel, the structure is simple and there is no protocol, it belongs to the connection equipment of the physical layer, which plays the role of signal amplification, and the data transmission adopts broadcast type, so it is suitable for small LAN erection, and the network performance decreases with the increase in the number of hosts in the same local area network.

The router is a more advanced device, which is a connection device at the network layer, which contains many protocols, and is generally used to connect multiple LANs, and can be used to divide virtual LANs. In addition to all the functions of a switch, the router also has a powerful routing function (IP protocol). The downside is that the data throughput is small and the speed is slow.

If you are connected to several computers, I suggest you use a switch, the router is not needed (the price is large), the hub is too backward, the machine is too conflicting, use the switch.

Of course.

1.The hub does not have a routing function. It is simply to connect 2 machines into a local area network2The router has a routing function. Equivalent to a computer.

3.With a modem+ hub without routing, share the Internet and complex. Hosts need to be set up.

4.Use a modem+ router without routing. Shared internet access and simplicity. It's just a matter of simply setting up the route.

Suppose you have two computers at home, and you go to the telecommunications bureau to apply for an Internet account, and you want to use the two at the same time, you must use a router. To use the hub, you must apply for two accounts. The hub and the line are connected in parallel, and the network speed of the two computers is not affected.

The hub works at the data link layer of the OSI.

Routers work at the network layer.

A hub is something that implements relay functionality and brings together multiple hosts.

A router can be used in place of a hub.

If the network is restricted from using the routing feature.

If your LAN is still working properly.

That's the equivalent of a hub.

Hope it helps.

The principle is different.

A router has a routing function, while a hub simply divides the network bandwidth.

The hub basically means connecting several wires, and it is not practical to have a large number, and it is to distribute the bandwidth of a line evenly to all lines, while the router allocates all the lines as separate lines, and there is no impact between the lines, which is suitable for large-scale LANs, such as Internet cafes.

A router is a multi-port device that can connect LAN and WAN networks with different transmission rates and operate in a variety of environments, as well as different protocols. Routers belong to the third layer of the OSI model.

A hub, on the other hand, is just a physical layer connection, connecting a computer or terminal with the same transmission rate and protocol type.

To put it simply, routers are used for connections between the same or different types of networks, while hubs are only responsible for connecting different computers or terminals in one network and are applied to the connection of machines within the LAN, while routers are used for the connection between the LAN and the WAN, and between the WAN and the WAN.

Functionally speaking, a hub is a multi-port bridge that is used to construct the core device of a star LAN, which works at the physical layer. In fact, it is a circuit ring inside, or it belongs to the working mechanism of the ring network. Data is still broadcast when transmitted, and network storms are very likely to occur when data is transmitted at multiple points on the network at the same time, resulting in a significant decrease in transmission efficiency.

A router is a key device used to connect two networks, such as connecting two LANs, or connecting a LAN to a wide area network (INTERNET). Routers work at the network layer (layer 3). It can determine the destination IP address of the packet and send it to the correct network, thereby effectively reducing the packet traffic between networks.

The first two are more professional. For the novices, to put it simply,
