Question details

OSI Model and Basics of Networks 1. A client sends a packet to a server through a satellite, which is 40,000 km above the earth. What is round up latency of sending such a packet 2. A message with 1024bits is sent in packets. Each packet has 128bits, 96bits of which is used to carry information and the rest for the header and error detection. What is the overhead of the packet? How many packets are needed to send the message for a node to another node? 3. If a packet could be corrupted in a probability of P/ = 10%. How many packets is needed to send the above message succesfully in average, averagely? 4. What are the channels, data rates and bandwidths of a WiFi system and a celluar system, such as Verizon in service in Dearborn? 5. Three hosts send packet over a shared bus. Each host takes p = 0.35 probability to send its packet, indepdently, what is the probability of the collisi which is defined as the probability of the case that more than 2 hosts send packet 101 isport nuapy as np print(d/c4) 1824 -96 pt.Ο. 1 print (1-96/128) print (np.ceit(sz/10)) print (np.ceit(sz/100)r) p9.35 .5333333333333333 0.25 11.0 2-222222222222223 0.4436249999919994
