Answer:C) PEAP(Protected Extensible Authentication Protocol)

Explanation: PEAP(Protected Extensible Authentication Protocol) is the protocol that is used in point-to-point network connection and wireless network connection.It is the version of EAP(Extensible Authentication Protocol) with the advantage of protection to maintain the security.

Other options are incorrect because EAP-FAST is the EAP protocol with that has flexible authentication through secure tunneling, EAP-TLS is the EAP protocol with the transfer layer security and EAP is used for the expansion of authentication method for the network between internet and computer system.Thus, the correct option is option(c).

java Two smallest numbers Write a program that reads a list of integers, and outputs the two smallest integers in the list, in a
SashulF [63]

Answer:

The code to this question can be defined as follows:

import java.util.*;//import package for user input

public class Main //defining a class

{

public static void main(String[] args)//defining main method  

{

   int m1,m2,num,t,i;//defining integer variable

   Scanner incx = new Scanner(System.in);//creating Scanner class object

   m1 = incx.nextInt();//input value

   m2 = incx.nextInt();//input value  

   if (m1 > m2)//use if block to check m1 greater than m2  

   {//swapping value

       t = m1;//holding m1 value in t

       m1 = m2;//defining m1 that take m2

       m2 = t;//holding m2 value  

   }

   for (i = 2; i < 6; i++)//defining for loop  

   {

       num = incx.nextInt();//input value  

       if (num < m1) //defining if block to smallest value

       {

           m2 = m1;//holding m2 value in m1

           m1 = num;//holding num value in m1

       }  

       else if (num < m2)//defining if block to smallest value  

       {

           m2 = num;//holding num value in m2

       }

   }

       System.out.println(m1 + " " + m2);//print two smallest values

   }

}

Output:

5

10

5

3

21

2

2 3

Explanation:

In the above code, five integer variable "m1, m2, num, t, and i" is declared, in which it creates the scanner class object for inputs the value and use m1 and m2 use to the input value.

In the next step, if a block is used to swap the value and pass into the for loop that use if block to find the two smallest values and hold its value into the m1 and m2 and print its value.

Assuming a computer has a single processor and a single core with no support for parallel execution, explain why running a multi
IRISSAK [1]

Answer:

Explanation:

Before we go deep into this question lets have some brief knowledge on parallel execution, parallel processing and multi tasking.

Parallel Execution : in this two or more tasks or program can be executed parallel or simultaneously.

For example if there are two processors and four programs to be executed then it executes two at a time.

Multi tasking: in this two or more tasks can be performed simultaneously switching between them without exiting any application.

For example we use notepad, word pad, excel sheet, chrome all at a time switching between each other.

Multi Threading: It is splitting up the program into different threads.If the contents in the program are independent on each other then the program can be split into multi threads and can be processed.

Multi threading in multi core or processing unit : In this threads are executed parallel or simultaneously in different processes.

For example if there are two processors then one multi threaded program can execute two threads in two different processors.

Multi threaded program in single core unit : In this, program is multi threaded where as threads cannot execute parallel or simultaneously. they sholud be executed by the same processor. So they should wait in queue

Ex: consider three tasks of 6 secs each and multi threaded each into three threads of two seconds.

Task1 3secs > task2 3secs > task3 3 secs it repeats until each task is completed

Total time taken is 3+3+3+3+3+3+3+3+3 is 18seconds...

If they are executed one by one without multi threading total execution time has no change..

Where as multi threading program has its advantages if different threads are executed at different place..

If one thread executes at network, another at printer and other processor then these three can execute at same time at different processors. Multi threading has its advantages but in single core systems it doesn't affect the performance.

Inter process communication consists of

Information Sharing, message passing, Modularity.

In shared memory inter process communication processes shares the memory between each other.

In message passing communication process communicates like request and replies for information and resources.

Interlocking is due to error in resource sharing and information sharing. It results in system collapse.

Al these process communication is required if there are two or more.processes but in single core it is not much useful and advisable.

In single core there will be a single processor, processing multi threaded program as it can access all the memory contents there will be no problem of process communication. Where as in multi core systems different processes may compete for same memory or resource.

In single core systems inter process communication makes things complex and these complexity is not much useful in any of the improvement in performance.
