It is like ASCII Code. By using ASCII, we- can represent limited number of characters. But using Unicode we can represent all of the characters used in the written languages of the world. 

Eg:- Malayalam, Hindi, Sanskrit,….

L.H.S. contains 2 & 8, so a 2 and a ≠ 8. 

R.H.S. contains 4 and 5, so b ≠ 2. 

L.H.S. < R.H.S. so a > b and a ≠ b also.

The possible values of a and b are given below.

Case I: 

a = 16 and b = 8 

(128)₁₆ = (296)₁₀ 

(450)₈ = (296)₁₀ 

So, a = 16 and b = 8. 

Then (16) = 1 × 16 + 6 × 16⁰ = (22)₁₀

The base of hexadecimal number system is 16 Hexadecimal number system .

Correct option: ii. b,d,c,a

1110.01011 = 1 × 23 + 1 × 22 + 1 × 21 + 0 × 20 + 0 × 2 – 1 + 1 × 2 – 2 + 0 × 2 – 3 + 1 × 2 – 4 + 1 × 2 – 5 

= 8 + 4 + 2 + 0 + 0 + 0.25 + 0 + 0.0625 + 0.03125 

= (14.34375)10

The correct answer is 16.

• Being a Base-16 system, the hexadecimal numbering system, therefore, uses 16 (sixteen) different digits with a combination of numbers from 0 through to 15.
• In other words, there are 16 possible digit symbols. 
• However, there is a potential problem with using this method of digit notation caused by the fact that the decimal numerals of 10, 11, 12, 13, 14, and 15 are normally written using two adjacent symbols.
• For example, if we write 10 in hexadecimal, do we mean the decimal number ten, or the binary number of two (1 + 0). 

• The base of some other important decimal numbers:
  • Octal number - 8
  • Decimal number - 10
  • Binary number - 2

Correct option: a. 19

Most Significant Digit

The base of Hexadecimal number system is 16.

Answer is 10

Convert each into decimal number system multiply and sum it up. 

(10)₂ = (2)₁₀ 

(11010)₂ = 1 × 2⁴ + 1 × 2³ + 0 × 2² + 1 × 2¹ + 0×2¹ 

= 16 +8 + 0 +2 + 0 

= (26)₁₀ 

(1010)₂ = 1 × 2³ + 0 × 2² + 1 × 2¹ +0 × 2⁰ 

= 8 + 0 + 2 + 0 

= (10)₂ 

(10100)₂ = 1 × 2⁴ + 0 × 2³ + 1 × 2² +0 × 2¹ + 0×2⁰ 

= 16 + 0 + 4 + 0 + 0 

= (20)₂ 

therfore 2 × 26 + 10 × 20 

= 52 + 200 

= 252 

So Mr. Geo has to pay Rs. 252/-

Exponent and Mantissa

Insert command is used to insert/add a tuple in a table.

Example: INSERT INTO Student 

VALUES (101,"Ananya", "Grover", 'F', '1984-08-11', 1);

DELETE

FROM Student

WHERE admno=101;

The base of decimal number system is 10

XOR is not a Basic Gate

There are three types of constructors.

1. Namely Default constructor.
2. Parameterized constructor.
3. Copy constructor.

1. Default Constructor:
A constructor which does not take any arguments is called a zero argument constructor. It is also called zero-argument constructor.

Features of default constructor are:

• All objects of a class are initialized to same set of values
• These constructors has no arguments
• These constructors are automatically called when every object is created.

The disadvantages of default constructor are:

• Different objects cannot be initialized with different values.
• Declaring a constructor with arguments hides default constructor.

2. parameterized constructor:
A constructor that takes one or more arguments is called a parameterized constructor.

The features of parameterized constructors are :

• parameterized constructors can be overloaded
• parameterized constructors can have default arguments and default values.

The different methods through which constructors can be invoked are implicit call and explicit call and using operator.

a. Explicit call:
It is a method of invoking a function where the declaration of object is followed by assignment operator followed by a constructor followed by argument list enclosed within parentheses.

b. Implicit Call:
It means the declarationof the object is followed by argument list enclosed in parentheses used with constructors The is used for the parameterized constructor which has exactly one argument.

3. Copy Constructor:
It is a parameterized constructor using which one object can be copied into another object. The copy constructor takes an object as argument and is used to copy values of data members of one object into other object.

The data manipulation commands are used for retrieval (view) of data, insertion of new data, modification of data or deletion. The DML commands include insert, delete and update.

1. INSERT command :
It is used to inserts new rows into the table.
Syntax:
INSERT INTO tablename (columnname1, columnname2,…) VALUES (value1, , value2, ..);
Example:
INSERT INTO student (Regno, name, Combn, fees) VALUES (1234, ‘Hemanth’, ‘PCMCs’,15000);

2. UPDATE command:
It can be used to change row values from a table. The SET keyword takes the column in which values need to be changed or updated. The WHERE keyword is used to filter the records in some conditions.
Syntax :
UPDATE tablename SET columnname = values WHERE Condition; Example: UPDATE student SET combn = ‘PCMCs’ where combn=’pcmc’;

3. DELETE Command :
It is used to delete/remove the tuples/rows from the table. All the rows will be deleted if WHERE clause is not used in the statement otherwise it selects the rows for delete which satisfies the condition.
Syntax:
DELETE from tablename WHERE Condition;
Example:
DELETE from student;
DELETE from student WHERE regno=1234;

Boolean Algebra

The base of octal number system is 8.

The statement is True

(100 0001)₂ = 65

Convert all numbers into decimal 

1. (1001)₂ = 1 × 2³ + 0 × 2² + 0 × 2² + 1 × 2⁰ 

= 8 + 0 + 0 + 1 

= (9)₁₀

2. (A)₁₆ = (10)₁₀ 

3. (10) = 1 × 8¹ +0 × 8⁰ 

= (8)₁₀ 

So the largest number is 4 . (11)₁₀

In manual data processing human beings are the processors. Our eyes and ears are input devices. We get data either from a printed paper, that can be read using our eyes or heard with ears. Our brain is the processor and it can process the data, and reach in a conclusion known as result. Our mouth and hands are output devices. In electronic data processing the data is processing with the help of a computer. In a super market, key board and hand held scanners are used to in. put data, the CPU process the data, monitor and printers (Bill) are output devices.
