Communications systemA communications system is a collection of individual telecommunications networks systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole. Communication systems allow the transfer of information from one place to another or from one device to another through a specified channel or medium.
Programming languageA programming language is an engineered language for expressing computer programs, typically allowing software to be written in a human readable manner. Execution of a program requires an implementation. There are two main approaches for implementing a programming language – compilation, where programs are translated ahead-of-time to machine code, and interpretation, where programs are directly executed.
SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.
Technical standardA technical standard is an established norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices.
CommunicationTransmission of information"Communicate" redirects here. For other uses, see Communicate (other).There are many forms of communication, including human linguistic communication using sounds, sign language, and writing as well as animals exchanging information and attempts to communicate with intelligent extraterrestrial life.Communication is commonly defined as the transmission of information.
Computer hardwareComputer hardware, commonly shortened to hardware, includes the physical parts of a computer, such as the central processing unit (CPU), random-access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. By contrast, software is a set of written instructions that can be stored and run by hardware.
Error detection and correctionIn information theory and coding theory with applications in computer science and telecommunications, error detection and correction (EDAC) or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver.
InformationInformation is an abstract concept that refers to something which has the power to inform. At the most fundamental level, it pertains to the interpretation (perhaps formally) of that which may be sensed, or their abstractions. Any natural process that is not completely random and any observable pattern in any medium can be said to convey some amount of information.
SynchronizationSynchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time. Systems that operate with all parts in synchrony are said to be synchronous or in sync—and those that are not are asynchronous. Today, time synchronization can occur between systems around the world through satellite navigation signals and other time and frequency transfer techniques.Semantics (programming languages)Semantics ofprogramming languagesLanguageLinguisticsIn programming language theory, semantics is the rigorous mathematical logic study of the meaning of programming languages. Semantics assigns computational meaning to valid strings in a programming language syntax. It is closely related to, and often crosses over with, the semantics of mathematical proofs. Semantics describes the processes a computer follows when executing a program in that specific language.ImplementationImplementation is the realization of an application, execution of a plan, idea, model, design, specification, standard, algorithm, policy, or the administration or management of a process or objective.SyntaxIn linguistics, syntax ( SIN-taks) is the study of how words and morphemes combine to form well-formed larger units such as phrases and sentences. Central concerns in this area of linguistics include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, cross-linguistic variation, and the relationship between structure and meaning (semantics).*As an Amazon Associate I earn from qualifying purchases.
