Some important Questions of my today's paper friends!

1. Write two benefits of network design in which there are multiple machines for handling the task instead of a single large machine?

2. Number of bits effected by any type of error depends upon data rate and duration of noise. How many bits may effect if we are sending data at the rate of 2kbps per second of noise 1/200?

3. In Go-Back n-Lost suppose the time has expired and ACK has not been reecieved yetthen whaat will the sender do in that case?

4. Due to some network impaiments data sent from sender has been cahnged befor reaching its destination. In this situation the receiver does not actually receive what is actually sent by the sender. You are required to write the names and discuss types of bit errors.

5.Calculate capacity of T1 line which carries 8000 frames and 24 voice channels.

6. In data communication a term PDU is widely used especially in the content of OSI. Discuss its structure briefly.
