A broadcast channel has 10 nodes and total capacity of 16Mbps. It uses polling for medium access. Once a node finishes transmission, there is a polling delay of 100 µseconds to poll the next node. Whenever a node is polled, it is allowed to transmit a maximum of 1500 Bytes. The maximum throughput of broadcast channel is: 8 Mbps 14 Mbps 100/11Mbps 750/85 Mbps

Consider a 8Mbps token LAN with a ring latency of 256µsec. A host need to transmit seizes the token, and then it sends a frame of 1024 bytes removes the frame after it has circulated all around the ring and finally releases the token. This process is repeated for every frame. Assuming that only a single host wishes to transmit, then the effective data rate (in Mbps) is? 4.53 5.36 6.7 9.4

A heavily loaded $1$ km long, $10$ Mbps token ring network has a propagation speed of $200$ meter per micro-second. Fifty stations are uniformly spaced around the ring. Each data packet is $256$ bits long, including $32$ bits of header. The token is of $8$ bits. What is the effective data rate of the network assuming the stations always have packets to transmit?
