Does the dormitory HUB slow down the internet speed?

The differences between switches and hubs are mainly reflected in the following aspects: (1) Different working levels in OSI RM (OSI reference model) Switches and hubs correspond to different levels in the OSI RM open architecture model, hubs work at the same time in the first layer (physical layer) and the second layer (data link layer), while switches work at least in the second layer, and more advanced switches can work in the third layer (network layer) and the fourth layer (transport layer). 2) The data transmission mode of the switch is different The data transmission mode of the hub is broadcast (broadcast) mode, and the data transmission of the switch is purposeful, the data is only sent to the destination node, but the first time it is sent using the broadcast mode when it cannot be found in its own MAC address table, and then because the switch has the MAC address learning function, it is no longer broadcast after the second time, and it is purposeful to send.

The advantage of this is that the data transmission efficiency is improved, there will be no broadcast storms, and there will be no listening by other nodes in terms of security. (3) Different ways of bandwidth occupation In terms of bandwidth occupation, all ports of the hub are the total bandwidth of the shared hub, and each port of the switch has its own bandwidth, so that the bandwidth of each port of the switch is actually much higher than the available bandwidth of the hub port, which determines that the transmission speed of the switch is much faster than that of the hub. (4) The transmission mode is different The hub can only use half-duplex mode for transmission, because the hub shares the transmission medium, so that the hub can only transmit one task at a time on the upstream channel, either receiving data or sending data.

The switch is different, it uses a full-duplex mode to transmit data, so it can receive and send data at the same time, which not only greatly accelerates the transmission speed of data, but also the throughput of the whole system The switch is at least twice as fast as the hub, because it can receive and send at the same time, in fact, it is far more than double, because the port bandwidth is generally many times wider than the hub. With the new 100m full-duplex HUB, there is no impact on speed.

Brother !There is a limit to how much money you can save!Let me show you why it's so slow!

You're using a cat to surf the Internet, and first of all, its maximum speed seems to be 64kIn addition, the broadband on the fourth floor is divided from the router on the second floor, if the router on the second floor is four, the fourth floor will occupy one, that is to say, the fourth floor has only a quarter of the resources. Then when I got to the fourth floor, I connected two more mouths, that is, another half.

So everyone gets very little resources!

The hub you are talking about is not called a hub, it is called a switch, and there will be a loss when you get down from the switch, but you can hardly notice that the IP of the machine under your switch is still assigned to the router, so the machine under your switch will still occupy your network speed.

The speed of 230k with 2M bandwidth is also normal, if it is really a hub, let's say it is a 100M 5-port hub, then the rate of each port is 20M, then it is more than enough to drive your 2M outer line.

But your bandwidth is only 2m, once someone shares with you, you will definitely not be able to reach the previous speed, and it is recommended that you see clearly whether it is a hub or a switch, it is better to use a switch, because his ** efficiency is higher than that of a hub.

If you can't reach 230, two people will have 1m per person, and it depends on what the other party does.

Your hub output port is 10M bandwidth.

Generally is sufficient.

If it really reaches 10M, your hard disk can't turn :)

The hub is 10M, you should use a small switch to reach 100M. **Not expensive either!

In general, the fastest network is 7 to 8 m s;

A speed of 100m s is simply not possible or necessary.

Of course, it's routing, and the routing allocation channel is like 10, and he allocates 10, and everyone uses 10If the hub is 10, if 5 is used, the remaining 2 people will be divided in 5. Do you understand this parable?

Overall, the Routing Switch hub.

As an intranet connection,,, it's basically the same... It's too stupid to be stupid anymore The hub is a connection, and it can't be used across networks, and the router is the connector of the two networks.

Dude, why did you ask again? First of all, the hub is a shared network, and the router is a switching network. The router has DHCP function, but the hub does not, so the machines under the hub must be set to IP in order to obtain the network address. For example, if you want to share multiple devices, if you use a router, you don't need to set an IP address for each machine, but you need to set an IP address for a hub.

The router is at the upper layer of the HUB cascade. You all want to go wireless with a notebook, and the hub has no wireless function, so you still have to use wireless routing, but the wireless routing can only realize the dialing function of an Internet account, even if you change it to a switch, it still can't realize that the three of you use the Internet access account that you apply for personally.

Of course, the router can be used as a switch, but if the 3 of you use one account and share the cost, you can save 2 broadband dollars. It's just that if you play a large game at the same time, the speed will be affected a bit.

Bandwidth of the incoming network = Sum of the bandwidths of each user port under the router port.

A router is only a network channel expansion channel, but does not increase or decrease the network bandwidth of the device, as a connection device for each channel.

Prepare. For example, if the network bandwidth is 20 Mbit/s and five devices are used, the total bandwidth of the five devices is 20 Mbit/s.

The general bandwidth of the hub (or switch) is 100M

According to China's current quality, the effective bandwidth is conservatively estimated to be 80M

If the total broadband accounts of all people in your dormitory exceed 80m, it will be affected.

If you have two 4m accounts, 80>8No effect.

Just buy a switch, tp-link, the kind is very small, tens of dollars is very cheap, and it won't get a card.

4Mbps bandwidth There is no need to consider the problem of using a switch to get stuck at all.

It used to be stuck with that old-fashioned hub hub, and the small hub has long been unused.

A hub, also known as a hub, is broadcast in nature and is not the same as a switch.

The data packets sent by the hub are group broadcasts, which are easy to cause network storms, and the switch is a little smarter, the first packet is also broadcast, and the second packet learns the purpose of this packetMAC, so that it is only sent to the destination IP and no longer sends broadcasts to the entire LAN, so as to be targeted.

Don't use hubs, that thing should have been phased out a long time ago.
