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.
Answer:
import random
print("Hello! I have a random number from 1 to 100! It is your job to try and guess it!")
number = random.randint(1,101)
guess = int(input("start to guess: "))
num_guesses = 1
while guess != number:
if guess > number:
print("lower")
guess = int(input("try again: "))
num_guesses +=1
elif guess < number:
print ("higher")
guess = int(input("start to guess: "))
num_guesses +=1
print("congrats it took you", num_guesses, "tries")
Explanation:
<span>Word can pull data from a variety of data sources to perform a mail merge. As part of the Microsoft Office suite, Word easily accepts data from Outlook, Excel, and Access, and other data sources such as web pages, OpenDocument text files, and delimited data files stored as plain text. And if you don't have an existing data source, you can create a new one in Word.
ALL OF THE ABOVE
