A 2km long broadcast LAN has 10^7 bps bandwidth and uses CSMA/CD.The signal travels along the wire at 2x10^8 m/s.What is the minimum packet size that can be used on this network?(in bytes)

# Ethernet....CSMA/CD

**poonamk**#2

As we know

Transmission Time = 2(Length of packet/Bandwith)

According to question ,equation will be 2(2000/2×108) …*equation 1*

Now, we have Length of packet = equation 1 * 107

= 25 bytes
