Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.
Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.
Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.
Answer:
Option E Components that interact to produce information
Explanation:
Information system is a system to collect, analyze and disseminate information. An information system consists of five components that work with each other to produce information:
- Computer hardware - physical machine that works with information
- Computer software - a set of computer instructions that tell computer hardware how to perform a task
- Telecommunications - components that connect a group of hardware as to establish a network. This usually includes WiFI technology.
- Databases and data warehouses - the place where the digital data are kept and retrieved.
- Human resources and procedures - human expertise that run the system by following some standard procedures.
favorite_color = input("Enter favorite color:\n")
pet = input("Enter pet's name:\n")
num = input("Enter a number:\n")
print("You entered: "+favorite_color+" "+pet+" "+num)
password1 = favorite_color+"_"+pet
password2 = num+favorite_color+num
print("First password: "+password1)
print("Second password: "+password2)
print("Number of characters in "+password1+": "+str(len(password1)))
print("Number of characters in "+password2+": "+str(len(password2)))
This works for me.
