Q4: What is the total delay (latency) for a frame of size 6 million bits that is being sent on a link with 5 routers each having a queuing time of 5 us and a processing time of 2 us. The length of the link is 3000 Km. The speed of light inside the link is 2 × 10^8 m/s. The link has a bandwidth of 10 Mbps. Which component of the total delay is dominant? Which one is negligible? Q5: A periodic signal has a bandwidth of 20 Hz. The highest frequency is 60 Hz. What is the lowest frequency? Draw the spectrum if the signal contains all frequencies of the same amplitude. Q6: Discuss Data Rate Limits and its factors. Q7: Discuss the difference between Attenuation and Distortion. Q8: A signal with 200 milliwatts power passes through 10 devices, each with an average noise of 2 microwatts. What is the SNR? What is the SNRdB? Q9: What is the bit rate for each of the following signals? a. A signal in which 1 bit lasts 0.001 s b. A signal in which 1 bit lasts 2 ms c. A signal in which 10 bits last 20 µs Q10: Between a high SNR and a low SNR, which one is more desirable? Explain the reason.

What is the value of the totient function ? If 37 is assigned to public key, what is the value of the private key? Choose among 3171, 3197, 7319, 8173, 9491
Question 10 Match the data types on the left with range of values they can represent. The range depends on the number of bytes (8-bits per byte). Assume that a modern 64-bit operating system is being used.
