A 1-km-long, 10-Mbps CSMA/CD LAN (not 802.3) has a propagation speed of
200 m/μsec. 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?
