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.
Answer:
Java in JavaScript does not correspond to any relationship with Java programming language.
Explanation:
The prefix Java in Javascript is there for historical reasons.
The original internal name of Javascript when it was created by Brendan Eich at Netscape was Mocha. This was released to public as Livescript in 1995. The name Livescript was eventually changed to Javascript in Netscape Navigator 2.0 beta 3 release in December 1995 after Netscape entered into an agreement with Sun Microsystem. The primary purpose of change of name seemed to be as a marketing aid to benefit from the growing popularity of Java programming language at that time.
Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialize the variables
int side;
//print the message
cout<<"Please enter the side of square: ";
cin>>side; //read the vale and store in the variable.
// for loop
for(int i=1;i<=side;i++){ //lop for rows
for(int j=1;j<=side;j++){ //loop for column
cout<<"$"; //print the '*'
}
cout<<endl;
}
}
Explanation:
Create the main function and declare the variable side.
print the message on the screen for the user and then store value enter by the user on the variable side.
take the nested for loop for print the pattern.
nested for loop means, loop inside another loop it is used for print the pattern having rows and columns.
the first loop updates the row number and the second the loop print the character '$' in the column-wise.
in the code,
if i = 1, for loop check the condition 1 <= 5 if the value of side is assume 5.
condition is true and the program moves to the second for loop and starts to print the character '$' five times after that, print the new line.
then, the above process repeat for different rows and finally, we get the pattern in square shape.

The question is a bit unclear. Are you asking how to add these values in this 2D array?
Explanation:
There are three main service models of cloud computing – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). There are clear differences between the three and what they can offer a business in terms of storage and resource pooling, but they can also interact with each other to form one comprehensive model of cloud computing.
aaS (Infrastructure as Service)
This is the most common service model of cloud computing as it offers the fundamental infrastructure of virtual servers, network, operating systems and data storage drives. It allows for the flexibility, reliability and scalability that many businesses seek with the cloud, and removes the need for hardware in the office. This makes it ideal for small and medium sized organisations looking for a cost-effective IT solution to support business growth. IaaS is a fully outsourced pay-for-use service and is available as a public, private or hybrid infrastructure.
PaaS (Platform-as-a-Service)
This is where cloud computing providers deploy the infrastructure and software framework, but businesses can develop and run their own applications. Web applications can be created quickly and easily via PaaS, and the service is flexible and robust enough to support them. PaaS solutions are scalable and ideal for business environments where multiple developers are working on a single project. It is also handy for situations where an existing data source (such as CRM tool) needs to be leveraged.
SaaS (Software as a Service)
This cloud computing solution involves the deployment of software over the internet to variousbusinesses who pay via subscription or a pay-per-use model. It is a valuable tool for CRM and for applications that need a lot of web or mobile access – such as mobile sales management software. SaaS is managed from a central location so businesses don’t have to worry about maintaining it themselves, and is ideal for short-term projects.
