Asad Malik 1.       ABSTRACT: Radio Frequency Identification (RFID) uses radio waves to track the movement of products. The item is identified by a unique number that is passed on easily to a pc. Middle size companies are experiencing RFID execution limitations.   The limitations are poor processing power, limited computational resources; poor data management etc., because of these issues RFID is not able to deliver what it is capable of, hence businesses are finding it difficult to adopt it. In this paper I have proposed a cloud platform for RFID system which will help RFID solution providers to meet RFID limitations and provide solutions which can meet the requirements of the businesses. Our platform will help meet the challenges which are un-answered yet and are affecting the reputation of radio frequency identification. Our platform wi

This is indeed the most asked question in object oriented world. After sometime i came to final conclusion and now i am able to define these 2 concepts precisely 1- Abstraction: Abstraction allows you to focus on what the object does, instead of going into its implementation details For example: var string = 5; int number = convert.toint32(string); Now you know that using convert.toint32 method, you can convert string to int, you know what this object does, but at the same time you don't know its implementation details. Implementation details of this object is hidden from the user, this is abstraction. 2- Encapsulation: It means hiding the implementation or internal details of how object does something. For example: if you look at the abstraction example, convert.toint32 implementation is hidden from outside world. This is very simple example of encapsulation.
