CLON
Question 3:
(Marks : 5+5= 10)
A 1-km-long, 100 Mbps CSMA/CD Local Area Network (LAN) has a propagation speed
200 m/usec. Repeaters are not allowed in this system. Data frames are 512 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. Correlate the effective data rate, excluding
overhead, assuming that there are
a) no collisions
b) collisions​

Answer 1

Answer:

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.
