Files and email messages sent over the internet are broken down into smaller pieces called packets
Answer:
five types of pointing devices
Explanation:
Ponting devices
Pointing means point something and the pointing devices are the input /peripheral devices those are used to point the pointer on the screen. We do move cursor on the screen to open the files or any icon.
There are many types of pointing devices but these are quite common which are given below
- Computer mouse
- Finger on touch screen.
- Joystick.
- Leap Motion.
- Light pen (pen)
1.Mouse
Mouse is most common type of input device that is used for pointing the data on the screen. We press it with our hands and keep pointing the things.
There are three types of mouse
- optical mouse
- wireless mouse
- trackball mouse.
2. Finger on touch screen
In this type of movement the fingers are input devices those we use to see the movement of pointer on the screen and this is most common in this century.
3.Joystick.
Joystick is another input device to point the cursor but it is mostly used in games. Children can use it smartly so it is inculcated in games usually.
4. Leap Motion
The Leap Motion (LM) controller is a latest 3D sensing device for hand posture interaction with a computer. It is having the capability sense the location of the fingers of the hands, as well as the palm position.
5.Light Pen
this is another pointing device which is mostly used to highlight and select the data on the screen.
Note: All of these above pointing devices are most common used now a days. These devices are having new conventions day by day for the ease of user. This era is basically the era of IT ,so the use of computer must be so easy and conventional for the user so, the innovations and improvement in such devices is made side by side.

Please Help! Unit 6: Lesson 1 - Coding Activity 2
Instructions: Hemachandra numbers (more commonly known as Fibonacci numbers) are found by starting with two numbers then finding the next number by adding the previous two numbers together. The most common starting numbers are 0 and 1 giving the numbers 0, 1, 1, 2, 3, 5...
The main method from this class contains code which is intended to fill an array of length 10 with these Hemachandra numbers, then print the value of the number in the array at the index entered by the user. For example if the user inputs 3 then the program should output 2, while if the user inputs 6 then the program should output 8. Debug this code so it works as intended.
The Code Given:
import java.util.Scanner;
public class U6_L1_Activity_Two{
public static void main(String[] args){
int[h] = new int[10];
0 = h[0];
1 = h[1];
h[2] = h[0] + h[1];
h[3] = h[1] + h[2];
h[4] = h[2] + h[3];
h[5] = h[3] + h[4];
h[6] = h[4] + h[5];
h[7] = h[5] + h[6];
h[8] = h[6] + h[7]
h[9] = h[7] + h[8];
h[10] = h[8] + h[9];
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
if (i >= 0 && i < 10)
System.out.println(h(i));
}
}
