Q85 MCQ GATE CS Medium 2 Marks 2024

CN → Network Routing

Consider a network path P-Q-R between nodes P and R via router Q. Node P sends a file of size 10^6 bytes to R via this path by splitting the file into chunks of 10^3 bytes each. Each of the links P-Q and Q-R has a bandwidth of 10^6 bits/sec, and negligible propagation latency. Router Q immediately transmits every packet it receives from P to R, with negligible processing and queueing delays. Router Q can simultaneously receive on link P-Q and transmit on link Q-R. Assume P starts transmitting the chunks at time t=0. Which one of the following options gives the time (in seconds) at which R receives all the chunks of the file?

Choose One:

A) 8.000

B) 8.008

C) 15.992

D) 16.000
