Give brief comparison of Broadcast, Unicastand Multicast?

Computers and Technology
1 answer:
Alex Ar [27]3 years ago
4 0

Answer:

In broadcast the message is transmitted from one to all , in uni cast we have one to one transmission and in multicast we have transmission from one to many.

Explanation:

If we take the example of a simple messaging application it will be clear. If a message is exchanged between one person to another, then it is uni casting. If a person sends a message to all the persons in his contact list then it is broadcasting and  if a person sends messages to select persons in his contact list then it is multi casting. In multi casting management of the group is required regarding who can receive messages which is not required in broadcasting.

Write a recursive method called lengthOfLongestSubsequence(a, b) that calculates the length of the longest common subsequence (l
kompoz [17]

Answer:

Explanation:

The following code is written in Java and creates the recursive function to find the longest common substring as requested.

 static int lengthOfLongestSubsequence(String X, String Y) {

       int m = X.length();

       int n = Y.length();

       if (m == 0 || n == 0) {

           return 0;

       }

       if (X.charAt(m - 1) == Y.charAt(n - 1)) {

           return 1 + lengthOfLongestSubsequence(X, Y);

       } else {

           return Math.max(lengthOfLongestSubsequence(X, Y),

                   lengthOfLongestSubsequence(X, Y));

       }

   }

Design and implement an algorithm that gets as input a list of k integer values N1, N2,..., Nk as well as a special value SUM. Y
satela [25.4K]

Answer:

Follows are the code to this question:

def FindPair(Values,SUM):#defining a method FindPair  

   found=False;#defining a boolean variable found

   for i in Values:#defining loop for check Value  

       for j in Values:#defining loop for check Value

           if (i+j ==SUM):#defining if block that check i+j=sum

               found=True;#assign value True in boolean variable

               x=i;#defining a variable x that holds i value

               y=j;#defining a variable x that holds j value

               break;#use break keyword

       if(found==True):#defining if block that checks found equal to True

           print("(",x,",",y,")");#print value

       else:#defining else block

           print("Sorry there is no such pair of values.");#print message

Values=[3,8,13,2,17,18,10];#defining a list and assign Values

SUM=20;#defining SUM variable

FindPair(Values,SUM);#calling a method FindPair

Output:

please find the attachment:

Explanation:

In the above python code a method, "FindPair" is defined, which accepts a "list and SUM" variable in its parameter, inside the method "found" a boolean variable is defined, that holds a value "false".

  • Inside the method, two for loop is defined, that holds list element value, and in if block, it checks its added value is equal to the SUM. If the condition is true, it changes the boolean variable value and defines the "x,y" variable, that holds its value.
  • In the next if the block, it checks the boolean variable value, if the condition is true, it will print the "x,y" value, otherwise, it will print a message.
