1. Internet is the best information technological device, through which we get know everything from the Internet.
2. In 2017 a study conducted by KPMG a Singapore-based organization along with, google, reported that, Tamil topped the list, among the most widely used languages in India where 42% are using the Internet in Tamil.
3. Moreover in 2021 onwards, 74% of people in India will access the internet using Tamil and it will be in the top usage of Internet in India.

The ability of the function to process the message or data in more than one form is called as function overloading. It implies that two or more functions in the same scope share the same name but their parameters are different. In this situation, the functions that share the same name are said to be overloaded and the process is called function overloading. The number and types of a function's parameters are called the function's signature.

Objects:
Represents data and its associated function together into a single unit. Objects are the basic unit of OOP. Basically an object is created from a class. They are instances of class also called as class variables. An identifiable entity with some characteristics and behaviour is called object.

#include< iostream.h >
using namespace std;
int main ( )
{
int i=1,num,avg,sum=0;
while(i < =5)
{
cout << "Enter the number :";
cin>>num;
sum=sum+num;
i++;
}
avg=sum/5;
cout << "The sum is" << sum << endl;
return 0;
}
Output
Enter the number: 1
Enter the number: 2
Enter the number: 3
Enter the number: 4
Enter the number: 5
The sum is 15

toupper(): This function is used to convert the given character into its uppercase. This function will return the uppercase equivalent of the given character. If the given character itself is in upper case, the output will be the same
Syntax:
char toupper( char c);
The following statement will assign the character constant 'K' to the variable c.
char c = toupper('k');

Need for operating system:
Operating System has become essential to enable the users to design applications without the knowledge of the computer's internal structure of hardware. Operating System manages all the Software and Hardware. Most of the time there are many different computer programmes running at the same time, they all need to access the Computers, CPU, Memory and Storage. The need of Operating System is basically- an interface between the user and hardware

Operating System works as translator, while it translates the user request into machine languagetfsinary language), processes it and then sends it back to Operating System. Operating System converts processed information into user readable form.

1. minimum(a,b)
2. --a,b
3. ifa
4. result:=a
5. else
6. result=b
7. --result=a \(\downarrow\) b

Recursion is another algorithm design technique, closely related to iteration. Using recursion, we solve a problem with a given input, by solving the same problem with a part of the input, and constructing a solution to the original problem from the solution to the partial input.

(i) RISC stands for Reduced Instruction Set Computers. They have a small set of highly optimized instructions.
(ii) Complex instructions are also implemented using simpler instructions, thus reducing the size of the instruction set.
(iii) Examples of RISC processors are Intel P6, Pentium IV, AMD K6 and K7.

(i) The opening screen of Windows is called "Desktop".
(ii) The desktop of your computer may look different
(iii) This is because Windows allows you to change the appearance of the desktop.
(iv) The desktop is the opening screen which consists of the icons as well as the Start button.
(v) The desktop can be used to store information temporarily or to move around documents and windows.

The inputs and outputs are passed between an algorithm and the user through variables. The values of the variables when the algorithm starts is known as the initial state, and the values of the variables when the algorithm finishes is known as the final state.

The state represented in a algorithm is set of variables. At any place the value of the variables are substituted and evaluation is done.

(i) Ubuntu has less hardware support for commercial/industrial/medical/ logistical therefore its less voted for use in big time backends.
(ii) Ubuntu doesn't support middlewares such as C panel, cloud linux and a plethora of other infrastructure or monitoring tools.
(iii) Hard to install graphic drivers especially for old hardwares. It is not possible to play the modern games, because of poor graphics quality.
(iv) The user switching from windows will not like the user experience on Ubuntu and will have difficulty in operating the OS.
(v) Ubuntu is not capable of playing MP3 files by default.

Impact printers:
(i) Impact printer refers to the class of printers that work by banging a head or needle against an ink ribbon to make a mark on the paper.
(ii) Impact printers are very noisy.
(iii) These printers can print on multi-part.
Eg: Dot Matrix, Line printers.

Input Device:
It is a peripheral device used to provide data and control signals to an information processing system. Eg: Keyboard, Mouse, Scanners, Digital cameras, Joysticks.
