A 10/100Mbps hub must share its bandwidth with each and every one of its ports. So when only one PC is broadcasting, it will have access to the maximum available bandwidth. If, however, multiple PCs are broadcasting, then that bandwidth will need to be divided among all of those systems, which will degrade performance.

A switch, however, keeps a record of the MAC addresses of all the devices connected to it. With this information, a switch can identify which system is sitting on which port. So when a frame is received, it knows exactly which port to send it to, without significantly increasing network response times.

And, unlike a hub, a 10/100Mbps switch will allocate a full 10/100Mbps to each of its ports. So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth. It's for these reasons a switch is considered to be a much better choice then a hub.

The hub acts as a central juncture point" all the devices connected to it will divide their bandwidth between all connected devices (as long as they are configured properly, this is automatic). If a hub is placed in a situation where it is one of many similar networks in the area, and its port is then used to connect to another network (say, a wireless router or switch), every computer attached to that hub will have half of its speed dedicated to communicating with the other hosts (or hubs) on the second network.

In a half duplex (HDX) transmission, a data packet is sent by one system and received by the other. Another data packet cannot be sent until the receiving system sends an acknowledgement back to the sender.

In a full duplex (FDX) transmission, both the sending and receiving systems communicate with each other simultaneously; in other words, both modems can send and receive data at the same time. This means a modem can be receiving a data packet while acknowledging the receipt of another.

Hubs always provide the entire speed what it is having to entire system that's 10mbps and since half duplex only it use the bandwidth for either sending or receiving both in switch and in hub and collision problem will occur in hub but this can be solved by switch so 10mbps bandwidth is provided for each system. But chance for collision is little high as of known to me.

Bandwidth sharing on the hub

Since the hub runs at 10 Mbps total, that 10 Mbps is shared between all users.
So, if only one user is communicating with the server → they can get the full 10 Mbps.
But if all 10 users try to communicate at the same time → the bandwidth is divided.
That means each user would get approximately 1 Mbps.

Switch provides the bandwidth of 10mbps to each node however hub divides it to 10 users by 1 mbps.

So when switch is connected to server, bandwidth from each host to the server will be 10 mbps i.e. Hub provide 1mbps to PC but switch provide 10 mbps to server.

Switch manages the bandwidth to 10mbps to each node. But hub divides it in 10 users by 1 mbps.

So when switch is connected to server so bandwidth from each host to the server is 10 mbps, its like hub provide 1mbps to PC but switch provide 10 mbps to server.

Hub sends traffic for all node so bandwidth is divided 10 mbps to 1 mbps each node.

And switch creates MAC Table so send traffic to one node to check specific node MAC address and then after sending traffic so 10 mbps speed to access node also 10 mbps.

I believe it is 10mb.

However, with half duplex, it is shared access CSMA/CD. Since only one person can successfully transmit at one time, it is still 10 mb.

If it was full duplex, the throughput would be 20mb with multiple collision domains.

According to the question 10 users are connected to the hub. The bandwidth is divided in to equal to the all hosts he he will give 10 Mbps it will divided in to equal to all hosts. I want explanation for this please give me.
