18: For a 10Mbps Ethernet link, if the length of the packet is 32bits, the transmission delay is ____________ (in microseconds)3.2320.32320

The question seems to be incomplete. However, I can guide you on how to calculate the transmission delay given the data rate and packet size.

The transmission delay (d_trans) can be calculated using the formula:

d_trans = packet size / data rate

Given a data rate of 10 Mbps and a packet size of 32 bits, you can substitute these values into the formula:

d_trans = 32 bits / 10 Mbps

Remember that 1 Mbps = 1,000,000 bits per second, so you can rewrite the formula as:

d_trans = 32 bits / 10,000,000 bits per second

Solving this will give you the transmission delay in seconds. To convert this to microseconds, multiply the result by 1,000,000 (since 1 second = 1,000,000 microseconds).
