Question

A 1-km-long, 10-mbps csma/cd lan has a propagation speed of 200m/sec. repeaters are not allowed in this system. data frames are 256 bits long, including 32 bits of header, checksum, and other overhead. the first bit slot after a successful transmission is reserved for the receiver to capture the channel in order to send a 32-bit acknowledgement frame. what is the effective data rate, excluding overhead, assuming that there are no collisions?

Answer 1

Explanation:

bytes of data (not including the 18 bytes of header & trailer). Data. 24. Ethernet ... At 10Mbps it takes 0.1μs to transmit one bit so 512 bits.

Answer 2
