# Computer Science and Information Theory

Information can be regarded as the ultimate solution of uncertainty; it renders the question of who or what an entity is, and hence both its nature and its attributes, Answers to all these questions are provided by the concept of information. The theory of information is a very complex one, which cannot be understood by most of the people even after having a theoretical knowledge of it. However, the basic idea of this theory is that information is a definite kind of data, which can be grasped, understood and used in a particular context. This concept has various other implications too. For instance it has been seen that the concept of information can be applied in various fields, which are not related to the scientific world like economics, sociology and computer science. It is true that some of the theories of information may appear strange to the people, but after having a proper knowledge of them they can prove to be useful in their respective fields of study.

The theory of information also deals with the problem of designing a system that can solve a certain problem, like calculating the value of certain random variables like number of digits in a series of numbers, and solving a mathematical problem without any input data (as in the case of computing the square root of a number). In the case of computers, this concept has provided a much better methodology of computing, which is called, information theory. New information theory has proved to be extremely useful for the field of computers and also provided a simple and efficient way of designing and using computers, in contrast to the older methods used in computers, which were based on the concepts of memory and processing power.

There have been many developments in the field of information systems in the recent years. These developments have provided a better methodology of computing and also provided a simple and efficient way of designing and using computers in comparison to the older methods used in computers. New information systems and computer science have proved to be extremely helpful for all types of organisations and industries and have contributed greatly to the progress of mankind.
