Understanding Understanding is a psychological process related to an abstract or physical object, such as a person, situation, or message whereby one is able to think about it and use concepts to deal adequately with that object. Understanding is a relation between the knower and an object of understanding. Understanding implies abilities and dispositions with respect to an object of knowledge that are sufficient to support intelligent behaviour.[1] Understanding is often, though not always, related to learning concepts, and sometimes also the theory or theories associated with those concepts. However, a person may have a good ability to predict the behaviour of an object, animal or system—and therefore may, in some sense, understand it—without necessarily being familiar with the concepts or theories associated with that object, animal or system in their culture [...More...]  "Understanding" on: Wikipedia Yahoo 

Loop (computing) In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language. Within an imperative programming language, a control flow statement is a statement the execution of which results in a choice being made as to which of two or more paths to follow [...More...]  "Loop (computing)" on: Wikipedia Yahoo

Calculator An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid state electronic calculator was created in the early 1960s. The pocket sized devices became available in the 1970s, especially after the first microprocessor, the Intel Intel 4004, developed by Intel Intel for the Japanese calculator company Busicom. They later became used commonly within the petroleum industry (oil and gas). Modern electronic calculators vary: from cheap, giveaway, creditcardsized models to sturdy desktop models with builtin printers. They became popular in the mid1970s (as integrated circuits made their size and cost small) [...More...]  "Calculator" on: Wikipedia Yahoo 

Algorithm In mathematics and computer science, an algorithm (/ˈælɡərɪðəm/ ( listen) ALgəridhəm) is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks. An algorithm is an effective method that can be expressed within a finite amount of space and time[1] and in a welldefined formal language[2] for calculating a function.[3] Starting from an initial state and initial input (perhaps empty),[4] the instructions describe a computation that, when executed, proceeds through a finite[5] number of welldefined successive states, eventually producing "output"[6] and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.[7] The concept of algorithm has existed for centuries and the use of the concept can be ascribed to Greek mathematicians, e.g [...More...]  "Algorithm" on: Wikipedia Yahoo 

Computer A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, and also general purpose devices like personal computers and mobile devices such as smartphones. Early computers were only conceived as calculating devices. Since ancient times, simple manual devices like the abacus aided people in doing calculations. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms [...More...]  "Computer" on: Wikipedia Yahoo 

Undergraduate Undergraduate education is the postsecondary education previous to the postgraduate education. It includes all the academic programs up to the level of a bachelor's degree.

Monoid In abstract algebra, a branch of mathematics, a monoid is an algebraic structure with a single associative binary operation and an identity element. Monoids are studied in semigroup theory, because they are semigroups with identity. Monoids occur in several branches of mathematics; for instance, they can be regarded as categories with a single object. Thus, they capture the idea of function composition within a set. In fact, all functions from a set into itself form naturally a monoid with respect to function composition. Monoids are also commonly used in computer science, both in its foundational aspects and in practical programming. The set of strings built from a given set of characters is a free monoid. The transition monoid and syntactic monoid are used in describing finitestate machines, whereas trace monoids and history monoids provide a foundation for process calculi and concurrent computing [...More...]  "Monoid" on: Wikipedia Yahoo 

Cash Register A cash register, also referred to as a till in the United Kingdom United Kingdom and other Commonwealth countries, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a drawer for storing cash and other valuables.

Number Theory Number Number theory, or in older usage arithmetic, is a branch of pure mathematics devoted primarily to the study of the integers. It is sometimes called "The Queen of Mathematics" because of its foundational place in the discipline.[1] Number Number theorists study prime numbers as well as the properties of objects made out of integers (e.g., rational numbers) or defined as generalizations of the integers (e.g., algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (e.g., the Riemann zeta function) that encode properties of the integers, primes or other numbertheoretic objects in some fashion (analytic number theory) [...More...]  "Number Theory" on: Wikipedia Yahoo 

Data Compression In signal processing, data compression, source coding,[1] or bitrate reduction involves encoding information using fewer bits than the original representation.[2] Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information.[3] The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted.[4] Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signal. Compression is useful because it reduces resources required to store and transmit data [...More...]  "Data Compression" on: Wikipedia Yahoo 

Prime Number A prime number (or a prime) is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 6 is composite because it is the product of two numbers (2 × 3) that are both smaller than 6. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple but slow method of checking the primality of a given number n displaystyle n , called trial division, tests whether n displaystyle n is a multiple of any integer between 2 and n displaystyle sqrt n [...More...]  "Prime Number" on: Wikipedia Yahoo 

Memorization Memorization Memorization is the process of committing something to memory. Mental process undertaken in order to store in memory for later recall items such as experiences, names, appointments, addresses, telephone numbers, lists, stories, poems, pictures, maps, diagrams, facts, music or other visual, auditory, or tactical information. The scientific study of memory is part of cognitive neuroscience, an interdisciplinary link between cognitive psychology and neuroscience. Development of Memorization Within the first 3 years of a child's life, they begin to show signs of memory that is later improved into their adolescent years. This includes short term memory, long term memory, working memory, and autobiographical memory. Memory Memory is a fundamental capacity that plays a special role in social, emotional, and cognitive functioning [...More...]  "Memorization" on: Wikipedia Yahoo 

Affect (psychology) Affect is a concept used in psychology to describe the experience of feeling or emotion. The term affect takes on a different meaning in other fields.[1] In psychology, affect mediates an organism's interaction with stimuli. The word also refers sometimes to affect display, which is "a facial, vocal, or gestural behavior that serves as an indicator of affect" (APA 2006). The affective domain represents one of the three divisions described in modern psychology: the cognitive, the conative, and the affective. Classically, these divisions have also been referred to as the "ABC of psychology",[citation needed] in that case using the terms "affect", "behavior", and "cognition". In certain views, the cognitive may be considered as a part of the affective, or the affective as a part of the cognitive; [2] it is important to note that "cognitive and affective states … [are] merely analytic categories". [3] Affective states are psychophysiological constructs [...More...]  "Affect (psychology)" on: Wikipedia Yahoo 

Repeating Decimal A repeating or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitelyrepeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of ⅓ becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.333…. A more complicated example is 3227/555, whose decimal becomes periodic at the second digit following the decimal point and then repeats the sequence "144" forever, i.e. 5.8144144144…. At present, there is no single universally accepted notation or phrasing for repeating decimals. The infinitelyrepeated digit sequence is called the repetend or reptend [...More...]  "Repeating Decimal" on: Wikipedia Yahoo
