Answer:
Broadcast message
Explanation:
The network models like OSI and TCP/IP suites have standard layers and protocols that governs the communication of end devices in a network.
The TCP/IP suite model has four layers which are application, transport, internet and network access layers. The network access does the work of both the data-link and physical layer of the OSI model.
When the packet is encapsulated in a data-link header and trailer, and needs to be sent to another unknown host, a broadcast message is sent to all the computers in the network to retrieve the remote host address for a unicast transmission to take place.
Answer:
- import java.util.Random;
- import java.util.Arrays;
- public class Main {
-
- public static void main(String[] args) {
- int n = 10;
- int [] myArray = new int[n];
- buildArray(myArray, n);
- System.out.println(Arrays.toString(myArray));
- }
-
- public static void buildArray(int[] arr, int n){
- for(int i=0; i < arr.length; i++){
- Random rand = new Random();
- arr[i] = rand.nextInt(90) +10;
- }
- }
- }
Explanation:
Firstly, create a method buildArray that take two inputs, an array and an array size (Line 12). In the method, use random nextInt method to repeatedly generate a two digit random number within a for loop that will loop over array size number of times (Line 13-15). The expression rand.nextInt(90) + 10 will generate digits between 10 - 99.
In the main program, call the build array method by using an array and array size as input arguments (Line 8). At last, print the array after calling the buildArray method (Line 9).
Answer:
def cal(n):
s=0
while n>0:
r=n%10
if(r==0 or r==4 or r==6 or r==9):
s=s+1
elif r==8:
s=s+2
n=n//10
print(s)
n=int(input("enter number:"))
print(n)
cal(n)
Explanation:
- Create a function to calculate count of closed path
.
- Create a variable to store count of closed path
.
- While number is positive
, extract last digit of n
.
- Reduce number by truncating last digit
.
- Make a function call to compute count of path.
Answer:
def leap_year_check(year):
return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)
Explanation:
The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.
int ensures the argument is read as an integer and not a float.
The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.
If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)
the function leap_year_check returns a boolean ; true and false if otherwise.
