Immersion and Interaction are the two most important features of virtual reality.
What is Immersion?
Immersion, also known as presence, refers to the degree of reality in which the viewer exists as the protagonist in the virtual environment. By wearing interactive devices such as helmet-mounted displays and data gloves, viewers can immerse themselves in a virtual environment and become a part of it.
What is Interaction?
Interaction refers to the user's ability to manipulate objects in the simulated environment as well as the natural degree of feedback from the real world. Human-computer interaction in VR technology is similar to natural interaction. There are two kinds of interactions: three-degree-of-freedom (3DoF) interactions and six-degree-of-freedom (6DoF) interactions.
What is Virtual reality (VR)?
Virtual reality (VR) is a simulated experience that uses pose tracking and 3D near-eye displays to immerse the user in a virtual world. A computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person wearing special electronic equipment, such as a helmet with a screen inside or gloves with sensors

Below you can see stringSize, which is implemented in Java
Answer:
(a): Yes, it is logically correct as the code does a loop through the all characters of the string and outputs the total amount of them within the string.
(b): It is poorly designed because it is not the most efficient way to get the size of the string. There is a much better way in obtaining it through s.length() and it also accounts for spaces as characters as well.
Explanation:
Hello! Let's help you with your question here!
Now, it is split up into two parts so I will explain them both as such.
Part A:For this part of the question. Yes, it would be logically correct. When the size is returned, it will return the number of characters in s. Let's break down the code step by step:
Code Rundown:int size = 0; (Initializing a size variable of type int and setting it to 0)for (int i = 0; i < s.length(); i++): We create what is known as an index i and have it loop until it reaches the length of the string (This is where we loop through the characters).size++; (For every loop, it'll just add 1 to size, essentially making it a counter).return size; (This returns the number within size after the loop is finished.)As you can see from the rundown, it initializes a counter and loops through each character of the string and increases the counter as it goes. So for this part, it is logically correct as it does give us the total amount of characters within a string which is considered the string size.
Part B:It is poorly designed under two reasons, one is more important than the other as the second one isn't really a requirement, it's just quality of life.
Reason 1 (The Important One):
The main reason why this is poorly designed is that it is not optimized. What it does here is going through the entire string and adds 1 to the counter every time there is a character. However, s.length() achieves the same thing. Instead of creating a counter and having it loop through the entire string and adding 1 to the counter for every character and then returning the counter. s.length() is a method that returns the length of a specified string. In this case, it returns the size of the string. To put it simply, the code in the example can be simplified to just:
private static int stringSize(String s) {
return s.length();
}
This would still give us the same result as the example without having to go through a loop. In programming and algorithms, we learn about time complexity. To put it simply, it is the time it takes for the program to complete. The faster it does without any errors, the more efficient and optimal it becomes. For the code example above, we have time complexity O(n). What this means is that the program needs to run through a loop (multiple checks) before finishing the code, this is the second fastest time. However, with the code I showed you above, it has a time complexity of O(1). For this code, it doesn't need to run any checks, it can just finish the code immediately. Therefore, the code in the example is not efficient.
Reason 2 (Quality of Life One):While the code does work well and does give you an accurate total size of the string every time, it however accounts for spaces as well. If you were to have a space in your string, it would bump the counter up as in Java, as spaces are considered a character because of this you won't get an accurate string size count if you want letters and symbols only. A way to improve it is to create a check within the loop that tells us if the character we are looking at, in the index, is a space or not. If it is a space, we subtract the size counter by 1 and move on. So the modified code would look like this:
public static int stringSize(String s) {
int size = 0;
for (int i = 0; i < s.length(); i++) {
size++;
char c = s.charAt(i);
if (c == ' ') {
size--;
}
}
return size;
}
Explanation:In the code, I am still adding 1 to the size counter still. However, in the bold. I create a variable c of type char and take the character of the string where the index is currently and use an if statement to determine if it is a space or not. If it is not, then the code repeats until the loop is done and then returns the size of the string. However, if it is a space, it'll subtract 1 from the size counter and will loop through the entire string doing this check and then returns the size of the string when it is done.

Write a program whose inputs are four integers, and whose outputs are the maximum and the minimum of the four values.
Ex: If the input is:
12 18 4 9
the output is:
Maximum is 18
Minimum is 4
The program must define and call the following two methods. Define a method named maxNumber that takes four integer parameters and returns an integer representing the maximum of the four integers. Define a method named minNumber that takes four integer parameters and returns an integer representing the minimum of the four integers.
public static int maxNumber(int num1, int num2, int num3, int num4)
public static int minNumber(int num1, int num2, int num3, int num4)
import java.util.Scanner;
public class LabProgram {
/* Define your method here */
public static void main(String[] args) {
/* Type your code here. */

How computer networks help in storage capacity and volume
Answer:
Having a network of computers (especially a server) allows you to store things on the network instead of your own computer's drive.
Explanation:
A network is a grouping of computers. Some of these computers are usually servers, especially in medium-sized companies. An example is having a server unit (usually with something like an Intel Xeon processor, and with at least 64GB of RAM) with the main feature being mass storage. It's like your own personal cloud! You'll often see a couple of 10TB drives stashed into one. Everything anyone could need to access is on there, as well as everything they need to save. This really helps if you give your employees basic laptops for WFH.
As a cool anecdote, I have 5.5TB of storage and am using 90% of it. You can never have enough! The cost adds up too, with 2TB of typical Hard Drive storage being a $50 expense. With laptops, you usually need an external HDD, which is slightly more expensive. Hence, cloud/network.

Given an array of distinct positive integers. Which of the following can be used to find the longest consecutive sub-sequence of integers? (Note that the consecutive numbers need not be sorted.)
For example, if the given array is [1 , 7, 3, 2, 8], the longest consecutive subsequence is [1 , 3, 2] as 1 , 2,3 are consecutive integers.
A Naive approach can be used to find the longest consecutive sub-sequence of integers.
What do you mean by Integers?Integers may be defined as whole numbers that can be positive, negative, or zero. It does not include any functional number or the numbers in the form of p/q. Examples of integers may include -5, 1, 5, 8, 97, etc.
The idea for finding the longest consecutive sub-sequence of integers is to sort or filter the array and find the longest subarray with consecutive elements. After sorting the array and eliminating the multiple occurrences of elements, run a loop and keep a count and max.
Therefore, a Naive approach can be used to find the longest consecutive sub-sequence of integers.

Product Cycle is all the stages games go through when being developed.
What's product cycle?
The product cycle is the period of time from the morning of processing to the finished product during which stocks( raw accoutrements , accoutrements ,semi-finished corridor, and finished factors) live in the manufacturing process. It takes up some of the manufacturing time and comprises of processing and halting phases.
Product cycle for developing a game :
Stage 1 of the game development process :
Although each step in the game development process is important, the original planning cycle has a direct impact on all posterior cycles. It's critical to begin the process of creating a computer game by gathering details about the willed end product, similar as technological specifications.
Stage 2 The product :
The product stage, which is broken down into multiple internal stages, is the stage that takes the longest and requires the topmost labor.
Stage 3 Quality control :
A game of any complexity needs to be tested to insure that it's error-free and bug-free. This is due to the fact that a single issue can have a negative impact on both the stoner experience and the overall enjoyment of a game. As a result, functional,non-functional, and beta testing are constantly carried out.
Stage 4 Launch :
The final stage of game product is the product debut, which is largely anticipated by all. But the story does not end with launch. Indeed after a game is finished, there are generally still enough bugs and faults, thus the game development platoon keeps adding new features and perfecting the game coincidently with its release. At the same time, testers gather the first stoner feedback to help inventors make significant adaptations.
Stage 5 Post-production :
Fixes and upgrades need to be continually covered after a game is released on the request to insure that it's stable and performing as intended. Studios should immaculately release updates constantly to cleave to the evolving specialized specifications of platforms.
