Describe a deep
and systematic
understanding of
Computer

principles, models
and technologies.
Question One
2 Marks
Consider a network with a data rate of 10 Mbps. Messages sent on this
network have a maximum size of 1000 bits, including a 16-bit control field.
1.
What is the number of messages required to send a file F of 4 Mbits
from one station to another?
2.
Assuming that a station cannot send a new message until it receives an
acknowledgment of the successful reception of the previously sent message.
The acknowledgment takes the form of a 16-bit message. A timer is set to a
duration T after the sending of each message. If time T expires before
receiving an acknowledgment, the sending station resends the same message.
The distance between the two farthest stations in the network is 1 km. The
signal propagation speed is v = 200,000 km/s. What is the minimum value of
T? (You ignore the queuing time and the processing time and use only the
propagation time and the transmission time)
