WebIn programming language theory and type theory, polymorphism is the provision of a single interface to entities of different types or the use of a single symbol to represent multiple different types. The concept is borrowed from a principle in biology where an organism or species can have many different forms or stages. The most commonly recognized major …

WebIn programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions. Operationally, a closure is a record storing a function together with an environment. The environment is a mapping associating each free variable of the function (variables that …

WebA computer language is a formal language used to communicate with a computer.Types of computer languages include: Construction language – all forms of communication by which a human can specify an executable problem solution to a computer. Command language – a language used to control the tasks of the computer itself, such as starting …

WebInstallation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution.Installation refers to the particular configuration of a software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install it.

WebThe seven standard Unix file types are regular, directory, symbolic link, FIFO special, block special, character special, and socket as defined by POSIX. Different OS-specific implementations allow more types than what POSIX requires (e.g. Solaris doors).A file's type can be identified by the ls -l command, which displays the type in the first character …

WebHistory. The software quality metrics of coupling and cohesion were invented by Larry Constantine in the late 1960s as part of a structured design, based on characteristics of “good” programming practices that reduced maintenance and modification costs.Structured design, including cohesion and coupling, were published in the article Stevens, Myers & …

WebIn information technology and computer science, a system is described as stateful if it is designed to remember preceding events or user interactions; the remembered information is called the state of the system.. The set of states a system can occupy is known as its state space.In a discrete system, the state space is countable and often finite.The system's …

WebComputer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system.The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict.

WebTypes Data hazards. Data hazards occur when instructions that exhibit data dependence modify data in different stages of a pipeline. Ignoring potential data hazards can result in race conditions (also termed race hazards). There are three situations in which a data hazard can occur: read after write (RAW), a true dependency

WebIn computer science, synchronization refers to one of two distinct but related concepts: synchronization of processes, and synchronization of data. Process synchronization refers to the idea that multiple processes are to join up or handshake at a certain point, in order to reach an agreement or commit to a certain sequence of action. Data synchronization …
