A sender wants to transmit a 10-bit binary data (1101011011). The sender uses CRC for error detection and hence uses a bit pattern of 10011 as the divisor.

a) How many bits are actually transmitted by the sender?

b) If all bits are received correctly, what is the bit pattern that the receiver receives?

1-About bus topology, which of the following statements is wrong?

a- In a bus topology, all nodes share a collision domain

b- In a bus topology, frame sent by one node will be received by all nodes in the network

c- It is not difficult to detect faults in a bus topology

d- In a bus topology, adding or deleting nodes will disrupt the entire network

The distance between two stations M and N is L kilometers. All frames are K bits long. The propagation delay per kilometer is t seconds. Let R bits/second be the channel capacity. Assuming that processing delay is negligible, the minimum number of bits for the sequence number field in a frame for maximum utilization, when the sliding window protocol is used, is (select the closest one):
