1 answer:
Dennis_Churaev [7]3 years ago
4 0

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:

Have a talk with your teacher. Ask why she doesn't believe you, and if it still doesn't work, have a talk with someone that can physically help you - a principle or another teacher may be the best solution.

Answer:

Following are the function to the Python Programming Language.

#define a function to read or crates the list

def GetUserValues():

 my_list=[]

 n=int(input("Enter range: "))

 for i in range(n):

   my_list.append(int(input(" :")))

 return my_list

#define a function to check the elements of the list

def IsListEven(mylist):

 #set the for loop

 for i in range(len(mylist)):

   #set if condition to check odd number

   if mylist[i]%2 !=0:

     #if condition is true retun false

     return False

 #otherwise return true

 return True

#define a function to check the elements of the list

def IsListOdd(mylist):

 #set the for loop

 for i in range(len(mylist)):

   #set if condition to check even number

   if mylist[i]%2==0:

     #if condition is true retun false

     return False

 #otherwise return true

 return True

#set variable to store list

l=GetUserValues()

#set if condition to check the function is true

if IsListOdd(l)==True:

 #then, print the message

 print("all odd")

#set elif condition to check the function is true

elif IsListEven(l)==True:

 #then, print the message

 print("all Even")

else:

 #otherwise print message.

 print("not even or odd")

<u>Output:</u>

Enter range: 5

:2

:4

:6

:8

:10

all Even

Explanation:

Here, we define a function "GetUserValues()" and inside the function.

  • Set the list data type variable "my_list" then, get input from the user in the variable "n".
  • Set the for loop which starts from 0 and end at the variable "n" then, get input from the user and appends inputs in the variable "my_list".
  • Then, we return list and close the function.

Then, we set a function "IsListEven()" and pass an argument "mylist" to check the elements is even or not, if the list elements is even then, return true otherwise, return false.

Then, we set a function "IsListOdd()" and pass an argument "mylist" to check the elements is odd or not, if the list elements is odd then, return true otherwise, return false.

Finally, we call and store the function in the variable "l" then, set conditions to check the list is even print "all even", if the is odd "all odd" otherwise, print "not even or odd".
