Question

7. Consider a user who needs to transmit 1.5 gigabytes of data to a server. The user lives in a small town where only dial-up access is available. A bus visits the small town once a day from the closest city, located 150 km away, and stops in front of the user’s house. The bus has a 100-Mbps WiFi connection. It can collect data from users in rural areas and transfer them to the Internet through a 1 Gbps link once it gets back to the city. Suppose the average speed of the bus is 60 km/h. What is the fastest way the user can transfer the data to the server?

Answer 1

The fastest way the user can transfer the data to the server is at 2 Minute 3 seconds.

Step-by-step explanation:

Solution

Given that:

The time it takes by bus from Users house to Town = 150 km/60 km/h= 2.5h = 9000 seconds

Now,

The users data to be transmitted over to the server = 1.5 GB

= 1.5*1024 MB

=1.5 *1024*8 Mb=12288 Mb

The time taken by Bus WiFi connection to transmit data = 12288 Mb /100 Mbps = 122.88 Seconds

Thus,

The user/individual can sit in bus and transmit his data to server in 2 Minute 3 Seconds
