Answer:
I. Algorithms can be written using pseudocode.
II. Algorithms can be visualized using flowcharts.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
The two statements which are true about algorithms are;
I. Algorithms can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. Algorithms can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).

Answer:
Watermark
Explanation:
This is actually called a Watermark. It is usually used as a way of showing the name or logo of the author who owns the content that is underneath the watermark. This is done so that individuals cannot steal the owner's work and use it as their own. Usually, the owner has the original version of the content without any watermark, as well as individuals that have purchased the content or a licence to use the content for personal or commercial usage.
Answer:
import java.util.Scanner;
public class ArraysKeyValue {
public static void main (String [] args) {
final int SIZE_LIST = 4;
int[] keysList = new int[SIZE_LIST];
int[] itemsList = new int[SIZE_LIST];
int i;
keysList[0] = 13;
keysList[1] = 47;
keysList[2] = 71;
keysList[3] = 59;
itemsList[0] = 12;
itemsList[1] = 36;
itemsList[2] = 72;
itemsList[3] = 54;
/* Your solution goes here */
for ( i = 0; i < SIZE_LIST; i++){
if (keysList[i]>50){
System.out.println(itemsList[i] + " "); } }
System.out.println("");
}
}
Explanation:
I will explain the whole program flow.
- There are two arrays here
- The first list (keysList) contains the following elements:
13 element at first position of the array (0th index)
47 element at second position of the array (1st index)
71 element at third position of the array (2nd index)
59 element at fourth position of the array (3rd index)
- The other list (itemsList) contains the following elements:
12 element at first position of the array (0th index)
36 element at second position of the array (1st index)
72 element at third position of the array (2nd index)
54 element at fourth position of the array (3rd index)
- The size of the array elements is fixed which is 4 and is stored in the variable SIZE_LIST.
- Then the loop starts. The loop contains a variable i which is initialized to 0. First it checks if the value of i is less than the size of the list. It is true as SIZE_LIST=4 and i=0.
- So the program control enters the body of the loop.
- In first iteration, IF condition checks if the i-th element of the keysList is greater than 50. As i=0 So the element at 0th index of the keysList is 13 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i increments by 1 so now i becomes 1.
- In next iteration loop again checks if the value of i is less than the size of the list which is true again so the body of the loop executes.
- IF condition checks if the i-th element of the keysList is greater than 50. As i=1 So the element at 1st index of the keysList is 47 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i is incremented by 1 so now i becomes 2.
- In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 2 which is less than SIZE_LIST so the body of the loop executes.
- IF condition checks if the i-th element of the keysList is greater than 50. As i=2 So the element at 2nd index of the keysList is 71 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 2 so the value at the index 2 of the itemsList is displayed in the output which is 72. Next value of i is incremented by 1 so now i becomes 3.
- In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 3 which is less than SIZE_LIST so the body of the loop executes.
- IF condition checks if the i-th element of the keysList is greater than 50. As i=3 So the element at 3rd index of the keysList is 59 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 3 so the value at the index 3 of the itemsList is displayed in the output which is 54. Next value of i is incremented by 1 so now i becomes 4.
- In next iteration loop again checks if the value of i is less than the size of the list which is now false as i=4 which is equal to the SIZE_LIST= 4. So the loop breaks.
- So the output of the above program is:
72
54
Answer:
b) BIOS/UEFI
Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, virtualization must be enabled in the BIOS/UEFI for VM (virtual machine) software to work.
BIOS is an acronym for Basic Input/Output System while UEFI is an acronym for Unified Extensible Firmware Interface. BIOS/UEFI are low-level software that serves as an intermediary between the operating systems and the computer's firmware or hardware components. The UEFI is actually an improvement of the BIOS and as such is a modernized software.
Basically, the BIOS/UEFI is a software which is an essential tool or feature which must be enabled to link the virtual machine with the hardware components of the computer.
