You have 10 users plugged into a hub running 10Mbps half-duplex. There is a server connected to the switch running 10Mbps half-duplex as well. How much bandwidth does each host have to the server?
100 kbps
1 Mbps
2 Mbps
10 Mbps
Explanation:
Each device has 10 Mbps to the server.

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.

In the above question hub is the state of half duplex at a time one user can only send the data or receive the data. So user gets 10mbps bandwidth.

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

So how come 10mbps is the speed.

If halfduplex affect the speed then it may be 1 mbps !

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.

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.

Switch actually recreates the signal with same 10 Mbps speed as half duplex but chances of collision is high. But use of hub still ambiguous.

Revise the concept of half duplex and full duplex in networking. It will be easier to understand this logic then.

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.
