ECONOMICS

INTRODUCTION:
          The origin of the term 'economics' lies in the Greek words Oiken and nomos which means 'laws of households'.
          According to Alfred Marshall, economics is the study of mankind in the ordinary business of life.
          According to Lionel Robbins, economics is a social science concerned with allocation of scarce resources among competing ends.
          In modern meaning economics renders help in various matters of decision making like
a) Production decision : What to produce?
                                          How to produce?
b) Exchange decision : What price to                                                     charge?
                                         Whom to sell?
c) Consumption decision : What to                                                             consume?
                                               How much to                                                    consume?
CLASSIFICATION OF ECONOMICS:
          Ragnar Firsch has classified economic into two broad categories
1. Micro Economics
2. Macro Economics
Micro Economics:
          The term micro have been derived from the Greek words Mikros which means 'small' Micro economics deals with behaviour of individuals for example that of a consumer or a producer or a market.
Macro Economics:
          The term Macro have been derived from the Greek words Makros which mean 'Large'. Macro economics deals with the behaviour of aggregates for example national income, agricultural output, industrial output, total employment and unemployment etc.
SCOPE OF ECONOMICS:
          The scope of economics means the limits of the subject matter of economics. Economics studies how wealth is produced, distributed, exchanged and consumed. So the scope of economics is broadly classified as under
a) Consumption:
          Satisfaction of human wants is called Consumption. This explains how people behave in consumption of goods and services inorder to maximise their satisfaction.
b) Production:
          Goods and services have to be produced with the help of factors of production. Production is another branch of economic.
c) Exchange:
          Goods and services cannot be produced at one place or at one point of time. Goods produced by one are exchanged for the goods produced by the other.
d) Distribution:
          Goods and services produced have to be paid for or rewarded. i.e) The land gets rent, labour gets wage, Capital gets interest and the organizer gets profit.
e) Public finance: 
          This branch of study in economics studies about the sources of revenue to the government and the principles governing the expenditure for the benefit of the people.

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...

Mathematics

MATHEMATICS           Mathematics is the science that deals with shapes, quantities and arrangements. Archmedes is known as the father of Mathematics (287BC-212BC). Mathematics seek and use patterns to formulates new conjuctures.They resove truth or false by using mathematical proof. Mathematics developed by counting, calculation, Measurements, Shapes and motion of physical objects.  Definition Mathematics has no general accepted definition. Until 18th century Aristotle defined mathematics as "the science of quantity". Many mathematicans take no interest in definition they simply say "Mathematics is what Mathematican do". Three leading definition of mathematics today are logicist, intutionist, and formalist. Logicist - In terms of Benjamin peirce, the definition of mathematics in terms of logic are "the science that draws necessary conclusion" and also said that " All mathematics is symbolic logic" by Mathematician Rusell. Intutionist - L.E.J.Bro...
