TSCII (Tamil Script Code for Information Interchange) is the first coding system to handle our Tamil language in an analysis of an encoding scheme that is easily handled in electronic devices, including non-English computers. This encoding scheme was registered in IANA (Internet Assigned Numbers Authority) unit of ICANN.

Sellinam and Ponmadal - are familiar Tamil keyboard layouts that works on Android operating system in Smart phone using phonetics.

Cracking is where someone edits a program source so that the code can be exploited or modified. "Cracking" means trying to get into computer systems in order to steal, corrupt, or illegitimately view data.

Multilevel Inheritance	Multiple Inheritance
In multilevel inheritance, the constructors will be executed in the order of inheritance.	If there are multiple base classes ,then it starts executing from the left most base class.

Function overloading is not only implementing polymorphism but also reduces the number of comparisons in a program and makes the program to execute faster. It also helps the programmer by reducing the number of function names to be remembered.

Structure is a user-defined which has the combination of data items with different data types. This allows to group of variables of mixed data types together into a single unit. The structure provides a facility to store different data types as a part of the same logical element in one memory chunk adjacent to each other.

Arguments or parameters are the means to pass values from the calling function to the called function. The variables used in the function definition as parameters are known as formal parameters. The constants, variables or expressions used in the function call are known as actual parameters.
Types : Default arguments and Constant Arguments.

Given Code	Corrected Code
if (x = 1) p = 100; else p = 10;	if (x ==1) p =100; else p = 10;

Null statement
The "null or empty statement" is a statement containing only a semi colon. It takes the following
form:
;// it is a null statement.
Null statement are commonly used as place holders in iteration statements or as statements on which to place labels at the end of compound statements or functions.
Compound statement
C++ allows a group of statements enclosed by pair of braces (). This group of statements is called as a compound statement or a block.
The general format of compound statement is:
{
statement 1;
statement 2;
statement 3;
}
for example:
{
int a,b;
a-8;
b=a+8;
}

Both the statements are equivalent as they declare 'ch' to be char and initialize it with the value of 67. Since this is the ASCII code for 'C', the character constant also can he used to initialize 'ch' to 67.

Character data type accepts and returns all valid ASCII characters. Character data type is often said to be an integer type, since all the characters are represented in memory by their associated ASCII Codes. If a variable is declared as char, C++ allows storing either a character or integer value.

(i) 39 - Decimal
(ii) 032 - Octal
(iii) 0XCAFE - Hexadecimal
(iv) 04.14 - Decimal

C++ program statements are constructed by many different small elelments such as commands, variables, constants and many more symbols called as operators and punctuators. Individual elements are collectively called as Lexical units or Lexical elements or Tokens. C++ has the following tokens:
(i) Keywords
(ii) Identifiers
(iii) Literals
(iv) Operators
(v) Punctuators

1. Recursion is a method of solving problems that involves breaking a problem down into smaller and smaller sub problems until user gets in to a small problem that it can be solved trivially.
2. Usually recursion involves a function calling itself. While it may not seem like much on the surface, recursion allows us to write elegant solutions to problems that may otherwise be very difficult to program.

No, the loop condition do not affect the loop invariant. Because the loop invariant is true at four points.
(i) at the start of loop
(ii) at the start of each iteration
(iii) at the end of each iteration
(iv) at the end of the loop

1. --minimum (a,b)
2. -- inputs: a, b are real numbers.
3. --output: result: minimum (a,b)

By choosing an option logout through the session indicator on the far right side of the top panel.

Advantages:
(i) It is free of cost
(ii) Accessible to everybody.
(iii) Not belongs to particular vendor.
(iv) It can be modified, for requirements.

File Extension is the second part of the file name. It succeeds the decimal point in the file name. It is used to identify the type of file and it is normally upto 3 to 4 characters long.
Ex. 1. exe,2. html.

Security Management features:
File access level security, System level security, Network level security.

(i) Keeping track of which portion of memory are currently being used and who is using them.
(ii) Determining which processes (or parts of processes) and data to move in and out of memory.
(iii) Allocation and de-allocation of memory blocks as needed by the program in main memory. (Garbage Collection).

HDMI (High Definition Multimedia Interface) is an audio/video interface which transfer the uncompressed video and audio data from a video controller, to a compatible computer monitor, LCD projector, digital television, etc.

Memory enables the computer to store the program. The memory unit is of two types:
(i) Primary memory
(ii) Secondary memory
The primary memory is used to store data temporarily and secondary memory stores the data permanently.

The ALU is a part of CPU where various computing functions are performed on data. ALU performs arithmetic operations such as addition, subtraction, multiplication, division and logical operations.

Data Information Data is a collection of facts from which the information may be derived. It is an unprocessed collection of facts in a manner suitable for communication, interpretation or processing. Information is a collection of facts from the conclusions can be drawn. Information is a processed facts, active, Business based and transformed from data. Eg. 134, 16, Kavitha Does not give meaning. Eg. Kavitha is 16 years old.
Conveys meaning.
