In mathematics and computer science, an algorithm is a finite sequence of rigorous well-defined instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. By making use of artificial intelligence, algorithms can perform automated deductions and use mathematical and logical tests to divert the code execution through various routes. Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus".
Computer programming is the process of performing a particular computation, usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms. The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.
In computing, a compiler is a computer program that translates computer code written in one programming language into another language. The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a lower level language to create an executable program.
In imperative programming, a computer program is a sequence of instructions in a programming language that a computer can execute or interpret. In declarative programming, a computer program is a set of instructions.
An essay is, generally, a piece of writing that gives the author's own argument, but the definition is vague, overlapping with those of a letter, a paper, an article, a pamphlet, and a short story. Essays have been sub-classified as formal and informal: formal essays are characterized by "serious purpose, dignity, logical organization, length," whereas the informal essay is characterized by "the personal element, humor, graceful style, rambling structure, unconventionality or novelty of theme," etc.
Whole language is an educational method originally developed for teaching literacy in English to young children. The method became a major model for education in the United States, Canada, New Zealand, and Great Britain in the 1980s and 1990s, despite there being no scientific support for the method's effectiveness. It is based on the premise that learning to read English comes naturally to humans, especially young children, in the same way that learning to speak develops naturally.
The Intel 8008 is an early byte-oriented microprocessor designed by Computer Terminal Corporation (CTC), implemented and manufactured by Intel, and introduced in April 1972. It is an 8-bit CPU with an external 14-bit address bus that could address 16 KB of memory. Originally known as the 1201, the chip was commissioned by Computer Terminal Corporation (CTC) to implement an instruction set of their design for their Datapoint 2200 programmable terminal. As the chip was delayed and did not meet CTC's performance goals, the 2200 ended up using CTC's own TTL-based CPU instead. An agreement permitted Intel to market the chip to other customers after Seiko expressed an interest in using it for a calculator.
A storyboard is a graphic organizer that consists of illustrations or images displayed in sequence for the purpose of pre-visualizing a motion picture, animation, motion graphic or interactive media sequence. The storyboarding process, in the form it is known today, was developed at Walt Disney Productions during the early 1930s, after several years of similar processes being in use at Walt Disney and other animation studios.
Roland Gérard Barthes was a French literary theorist, essayist, philosopher, critic, and semiotician. His work engaged in the analysis of a variety of sign systems, mainly derived from Western popular culture. His ideas explored a diverse range of fields and influenced the development of many schools of theory, including structuralism, anthropology, literary theory, and post-structuralism.
Bloom's taxonomy is a set of three hierarchical models used for classification of educational learning objectives into levels of complexity and specificity. The three lists cover the learning objectives in cognitive, affective and psychomotor domains. The cognitive domain list has been the primary focus of most traditional education and is frequently used to structure curriculum learning objectives, assessments and activities.
A technical writer is a professional information communicator whose task is to transfer information between two or more parties, through any medium that best facilitates the transfer and comprehension of the information. Technical writers research and create information through a variety of delivery media. Example types of information include online help, manuals, white papers, design specifications, project plans, and software test plans. With the rise of e-learning, technical writers are increasingly becoming involved with creating online training material.
Ecocomposition is a way of looking at literacy using concepts from ecology. It is a postprocess theory of writing instruction that tries to account for factors beyond hierarchically defined goals within social settings; however, it doesn't dismiss these goals. Rather, it incorporates them within an ecological view that extends the range of factors affecting the writing process beyond the social to include aspects such as "place" and "nature." Its main motto, then, is "Writing Takes Place".
Technical writing is writing or drafting technical communication used in technical and occupational fields, such as computer hardware and software, engineering, chemistry, aeronautics, robotics, finance, medical, consumer electronics, biotechnology, and forestry. Technical writing encompasses the largest sub-field in technical communication.
The megahertz myth, or in more recent cases the gigahertz myth, refers to the misconception of only using clock rate to compare the performance of different microprocessors. While clock rates are a valid way of comparing the performance of different speeds of the same model and type of processor, other factors such as an amount of execution units, pipeline depth, cache hierarchy, branch prediction, and instruction sets can greatly affect the performance when considering different processors. For example, one processor may take two clock cycles to add two numbers and another clock cycle to multiply by a third number, whereas another processor may do the same calculation in two clock cycles. Comparisons between different types of processors are difficult because performance varies depending on the type of task. A benchmark is a more thorough way of measuring and comparing computer performance.
In software engineering, profiling is a form of dynamic program analysis that measures, for example, the space (memory) or time complexity of a program, the usage of particular instructions, or the frequency and duration of function calls. Most commonly, profiling information serves to aid program optimization, and more specifically, performance engineering.
An annotated bibliography is a bibliography that gives a summary of each of the entries. The purpose of annotations is to provide the reader with a summary and an evaluation of each source. Each summary should be a concise exposition of the source's central idea(s) and give the reader a general idea of the source's content.
ITK is a cross-platform, open-source application development framework widely used for the development of image segmentation and image registration programs. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Typically the sampled representation is an image acquired from such medical instrumentation as CT or MRI scanners. Registration is the task of aligning or developing correspondences between data. For example, in the medical environment, a CT scan may be aligned with an MRI scan in order to combine the information contained in both.
The rhetorical modes are a long-standing attempt to broadly classify the major kinds of language-based communication, particularly writing and speaking, into narration, description, exposition, and argumentation. First attempted by Samuel P. Newman in A Practical System of Rhetoric in 1827, the modes of discourse have long influenced US writing instruction and particularly the design of mass-market writing assessments, despite critiques of these classification's explanatory power for non-school writing.
The following article is a supplement to the article Turing machine.
In computer engineering, computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. The architecture of a system refers to its structure in terms of separately specified components of that system and their interrelationships.
