Ques:What is the difference between data & information?

The difference between data & information is given below:

There are three answer.You can accept one or all of them.


                                                      Answer No:1
1.The concept of data: numbers, text, pictures, sound and moving images.

The concept of information: the information is useful data.

2. Data is the part of information.

Information contains data.

3. But data is unprocessed material.

Information is the results of data processing.

4.Data isn’t relative and timeliness.

But Information is relative and timeliness.

                                          

                                                                Answer No:2

                                               
1.The information is a reflection of the objective things property. Impact is after data processing and objective of human behavior manifestations.

The data reflect the objective things, property records, is concrete manifestation of information.

2. Anything properties are expressed through data. Data become information after intensive processing.
The information must be spread through the data in order to influence on human.

3. For example: Data 1, 3, 5, 7, 9, 11, 13, it is a set of data, if we analyze it can be drawn that it is an arithmetic sequence, we can easily know the figures behind it is a message. It is useful data 1,3,2,4,5,1,41 data. It can not tell us anything, so it is not information.

                                                         Answer No:3

1. Information: objective world and a state of movement, and its state changes reflect, can be passed, is useful.

Data: is the recording of the objective facts of the physical symbol or a combination of these physical symbols.
2.The data itself has no specific meaning, just record the nature of things, shape, number of features abstract symbols.

Information is obtained after the useful data processing and it has specific meaning.

3.Example: Data  is like a someone’s poker face, information is like someone’s smiling face. 

Ques: What do you mean by operator and operand? What are unary operators? How many operands are associated with a unary operator?

The definition of operator ,operand and unary operator is given below.

Solution:

Operator: C is very in built-in operators.An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations.

Operand: The data items that operators used are called operand.

Unary operator: C includes a class of operators that act upon a single operand to produce a new value.Such operators are known as Unary operator.

Unary operator are below:

+ + ( Increment).
- - (Decrement).
- (unary minus ).

How many operators are associated with a unary operator: Only one operator is associated with a unary operator.Such as....


a++ ......here is one operand.
++a .....here is one operand.
