Answer:

a. The process has done something wrong (segmentation fault, etc.)

Explanation:

Events that cause signals to be generated by kernel and sent to childless foreground process is the process has done something wrong(segmentation fault), as Hardware exceptions generate signals,for example, divide by 0 or invalid memory reference. These conditions are usually detected by the hardware, and the kernel is notified. The kernel then generates the appropriate signal for the process that was running at the time the condition occurred.

Write a program that sorts an array of 20 random numbersin the range from 0 through 1000.
Nuetrik [128]

Answer:

#include<iostream>

#include<stdlib.h>

#include<time.h>

#include <algorithm>

using namespace std;

//main function program start from here

int main(){

   //seed the rand() function

   srand(time(NULL));

   //initialization

   int arr[20];

   //generate the 20 random number

  for(int i=0;i<20;i++){

   arr[i]=rand()%1000;   //store in array

  }

  sort(arr,arr+20); //sort the array by inbuilt function

  cout<<"The sorted array is."<<endl;

  //for display the each element in the array

  for(int i=0;i<20;i++){

   cout<<arr[i]<<endl;

  }

}

Explanation:

Create the main function and declare the array with size 20.

Take a for loop and generate the random number 20 times. For generating a random number, use the function rand();

rand() function which defines in the library stdlib.h, generate the random number within the range.

for example:

rand() % 20: generate the number between 0 to 19 ( Exclude 20).

for generating the random number different for every time, then we have to use srand() function and time function which defines in time.h library.

After that, store the number in the array.

Finally, take another loop and print all elements one by one.

NISA [10]

Answer:

Explanation:

Given, total payload is: 2000 bytes

 MTU is: 1500 bytes

 Header is: 20 bytes

 Base header is: 40 bytes

Total number of fragments = Total Payload / MTU

                                            = 2500 / 1500

                                            = 2 fragments

Fragment     Base header    Fragmentation header     Authentication  

                                                                                                     header + Data

1                  40 bytes                  8 bytes                              20 bytes +772bytes

2                 40 bytes                   8 bytes                                 792 bytes

Rasheed is memorizing his multiplication tables by using flash cards. He does this frequently enough that eventually he does not
slavikrds [6]

Answer:

Long-term memory

Explanation:

There are two common types of memory - Long-term and short-term.

In short-term memory, information are stored just for a very short time before they are eventually discarded or transferred to the long-term memory. It is sometimes called working memory. For example, short-time memory can be used to remember that a particular event is going to be by 12pm today. After the event, the information might either be discarded or pushed to the long-term memory.

In long-term memory, information are stored for a very long term, almost permanently. For example, long-term memory enables you to remember an event that has taken place in the past. In the case of Rasheed, he has so much learned the multiplication tables in such a way that information on the tables have been stored indefinitely in a part of his brain called hippocampus. Every time he needs the multiplication tables, they are always available. So he is already taking advantage of the long-term memory.
