Answer: 5 Frames

Explanation: When the data packet is transferred from sender to receiver , it forms frame.If there are five networks through which the data packets travels then there are five frames as well because packet moves one by one from every frame.

Other options are incorrect because the number of frame in network from source to destination will be equal to the number of networks .So, it cannot be 1 ,2 and 6 frames.Thus the correct option is 5 frames.

Consider the following code segment, where num is an integer variable.int[][] arr = {{11, 13, 14 ,15},{12, 18, 17, 26},{13, 21,
Setler79 [48]

Answer:

c. 16 17

Explanation:

Given

num = 14

The above code segment

Required

The output

In the code segment, we have the following iterations:

for (int j = 0; j < arr.length; j++) and for (int k = 0; k < arr[0].length; k++)

The above iterates through all the elements of the array.

The if condition is true, only on two occasions

(i) When i = 0; j = 2

(ii) When i = 3; j = 0

i.e.

arr[0][2] = 14

arr[3[0] = 14

So, the result of the print statement is: j + k + arr[j][k]

(i) When i = 0; j = 2

j + k + arr[j][k]  = 0 + 2 + 14 = 16

(ii) When i = 3; j = 0

j + k + arr[j][k]  = 3 + 0 + 14 = 17

<em>Hence, (c) 16 17 is true</em>

Write a program that reads the data from rawdata_2004.txt into a dictionary whose keys are country names and whose values are pe
san4es73 [151]

Answer:

import re

def country_capita():

   #opens file

   file=open("inputfile.txt", "r")

   dictionary=dict()

   #reads line by line

   for line in file.readlines():

       # substitutes for multiple space a single space

       line = re.sub(r"[\s]{2, }", ' ', line)

       list=[]

       #splits line on space

       list=line.split(" ")

       #put into dictionary

       dictionary[list[1]]=list[2]

#   get input

   while True:

       choice=input("Enter the country name or quit to exit: ")

       if choice=="quit":

           break

       elif choice in dictionary.keys():

           print(dictionary[choice])

       else:

           print("Invalid Country")

country_capita()

Explanation:

Using python to code this program. First we, (line 1) import the re module which offers us a set of functions that allows us to search a string for a match. ((line 2) Next we define a function country_capita() that will open rawdata_2004.txt, read the information within line by line and create a dictionary list. The we create a while loop with conditional statements that prompt the user to enter country names, print the corresponding values and stops when the user enters quit.
