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.
I would use a biometric machine that scans a fingerprint and a eye retina then calls up my bank information from the scan. Who wants to carry a card around anyway?
The answer is D) Projector because with a projector, its in the name project so it can anything u put on their, and put it on a virtual screen that can be put on a wall, so everyone can see.
Answer:
In a function prototype the heading is followed by a semicolon, whereas in a function definition the heading is followed by a function block.
Explanation:
As the function prototype only declares the function and the function definition defines the operations in the function.
e.g:
add(int x, int y); is the prototype
add(int x, int y)
{
int sum;
sum 
x
y;
} is the function definition.
