Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
well not a note but here are some few points
Explanation:
1 Computers can have the huge impact on employment of people like job and other stuff.
2 lots of human can be jobless or unemployed
3 it can cuz impact on the health of peoples
4 it also can make us lazy and and lack of self knowledge
3D printing helps to reduce the time it takes for a manufacturer to create the product. This lets manufacturers invest their time to make flawless products because the production cycle time is reduced.
