The conventional $10$ Mbps Ethernet has a minimum frame size of $64$ bytes. As long as frames are longer than $64$ bytes, no padding is used. Now consider Gigabit Ethernet $(1$ Gbps$)$ which forces a minimum frame size of $512$ bytes by padding any smaller frames. Frames smaller than $512$ bytes waste usable bandwidth and hence reduce the effective bandwidth of the LAN. Calculate the effective bandwidth of Gigabit Ethernet where $50\%$ of the total frames transmitted on the LAN are $64$ bytes long and the rest are all $512$ bytes long. I Ignore any bandwidth waste due to Ethernet frame header. Consider only the waste due to the larger minimum frame size.$]$
