help me find out the solution of the questions of computer network given below
Q: -1
The round propagation delay for a 100 Mbps Ethernet having 48-bit jamming signal is 64 micro-sec. What is min frame size?
1. 400 bytes
2. 600 bytes
3. 800 bytes
4. 1400 bytes

Q: -2
The distance b/w two microwave towers, with the link capacity 100 Mbps, is 24 km and the speed of the signal is 3 x 108 m/sec. If the frame size is 16 Kb in the stop-and-wait protocol, what is the approximate link utilization? Assume that the ACK packets are negligible in the size and there are no errors during communication.
1. 33%
2. 50%
3. 66%
4. 75%

Q: 3
Two ground station are connected by 10 Mbps satellite link. The altitude of satellite is 36,000 km and the speed of the signal is 3 x 108 m/sec. What should be the package size for the channel utilization of 50% using go-back-100 sliding windows protocol? Assume that the ACK packets are negligible in size and there are no errors during communication.
(A) 1.5 Kbytes
(B) 3 Kbytes
(C) 4.5 Kbytes
(D) 6 Kbytes

ETC,
Plz send me any link for this type of Question and solution.
Thanks
 
Hello Neetu
thanks for help.
Its give me some new question
but link is not enough for the Numerical questions:
i will also check the book for the same,

Amit, I'll try to find more numerical questions and post the links. Also, if you want the e-book for Kurose, then let me know.
