A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in the natural sciences and engineering disciplines, but also in the social sciences; physicists, engineers, statisticians, operations research analysts and economists use mathematical models most extensively.

Mathematical economics
Mathematical economics is the application of mathematical methods to represent economic theories and analyze problems posed in economics. It allows formulation and derivation of key relationships in a theory with clarity, generality, rigor, and simplicity. By convention, the applied methods refer to those beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, and mathematical programming and other computational methods.

Computer science
Computer science or computing science (abbreviated CS or CompSci) designates the scientific and mathematical approach in information technology and its applications, notably computer software and sometimes hardware. A computer scientist is a scientist who specialises in the theory of computation and the design of computers. Its subfields can be divided into practical techniques for its implementation and application in computer systems and purely theoretical areas.

Algorithm
In mathematics and computer science, an algorithm Listen/ˈælɡərɪðəm/ (originating from al-Khwārizmī, the famous mathematician Muḥammad ibn Mūsā al-Khwārizmī) is a step-by-step procedure for calculations. Algorithms are used for calculation, data processing, and automated reasoning. More precisely, an algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function.

Internet
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.

Frontier
A frontier is a political and geographical term referring to areas near or beyond a boundary. It was absorbed into English from French in the 15th century, with the meaning "borderland"—the region of a country that fronts on another country. The word "frontier" also means a region at the edge of a settled area, especially in North American development. It is a transition zone where explorers, pioneers and settlers were arriving.
