Q1.How long will it take to transmit a 1-GB file from one VSAT to another using a hub as shown in Figure below? Assume that the uplink is 1 Mbps, the downlink is 7 Mbps, and circuit switching is used with 1.2 sec circuit setup time.

Q2. Calculate the transmit time in the previous problem if packet switching is used instead. Assume that the packet size is 64 KB, the switching delay in the satellite and hub is 10 microseconds, and the packet header size is 32 bytes

(I want Q2 )

How long does it take to send a 15 MiB file from Host A to Host B over a circuit-switched network, assuming: - Total link transmission rate = 49.7 Gbps. - Network is FDM, with 7 permitted users, each with an equal bandwidth share. - A link connection requires a setup time of 84.5 ms. Your answer should be in miliseconds (ms) with one decimal place, and without the unit (e.g. "140.6" without the quotes)

The C++ program below simply copies the contents of one file to another file using standard in and standard out. Do a line-by-line conversion of the complete program into a closely equivalent C program that produces the same output given the same input. Note that the underscores are used solely to force indentation in Canvas. #include using namespace std; int main(void) { char symbol; cin.get(symbol); while (!cin.eof()) ___ { ___ cout.put(symbol); ___ cin.get(symbol); ___ } return 0; }

How long will it take her to rotate the sphere one time, starting from rest?

There is a girl pushing on a large stone sphere. The sphere has a mass of 8200 kgand a radius of 90 cm and floats with nearly zero friction on a thin layer of pressurized water. Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 30N and that the pressured water provides a frictionless support. 1) How long will it take her to rotate the sphere one time, starting from rest?...

A 50 inch long belt is used to transmit power from a motor to a working...

A 50 inch long belt is used to transmit power from a motor to a working shaft. The two sheaves involved are both the same size, hence the belt is not being used to reduce or increase speed or torque, but simply to “couple” two shafts. The motor’s rated power is 50 hp and the required service factor is 1.25. The motor speed is 1160 rpm and the sheave diameters are 7.9”. How many 5V belts are required here? What...

Step 1: Your program will now take its input from this file instead of from the user. Here's what you want to do: Remove the call to getUserInput(). You can also remove its definition and prototype if you like. For reasons that will become clear later, don't close the file until just before the return statement at the end of main. Run your code to make sure that the file is opened and read correctly. Hint: you may test the...
