Reliability (computer Networking)
In computer networking, a reliable protocol is a communication protocol that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for assurance, which is the term used by the ITU and ATM Forum, and leads to fault-tolerant messaging. Reliable protocols typically incur more overhead than unreliable protocols, and as a result, function more slowly and with less scalability. This often is not an issue for unicast protocols, but it may become a problem for reliable multicast protocols. Transmission Control Protocol (TCP), the main protocol used on the Internet, is a reliable unicast protocol; it provides the abstraction of a reliable byte stream to applications. UDP is an unreliable protocol and is often used in computer games, streaming media or in other situations where speed is an issue and some data loss may be tolerated because of the transitory nature of the data. Often, a reliable unicast protocol i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reliability (semiconductor)
Reliability of a semiconductor device is the ability of the device to perform its intended function during the life of the device in the field. There are multiple considerations that need to be accounted for when developing reliable semiconductor devices: # Semiconductor devices are very sensitive to impurities and particles. Therefore, to manufacture these devices it is necessary to manage many processes while accurately controlling the level of impurities and particles. The finished product quality depends upon the many layered relationship of each interacting substance in the semiconductor, including metallization, chip material ( list of semiconductor materials) and package. # The problems of micro-processes, and thin films and must be fully understood as they apply to metallization and wire bonding. It is also necessary to analyze surface phenomena from the aspect of thin films. # Due to the rapid advances in technology, many new devices are developed using new materials a ...

Reliability (statistics)
In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 (much error) and 1.00 (no error), are usually used to indicate the amount of error in the scores. For example, measurements of people's height and weight are often extremely reliable.The Marketing Accountability Standards Board (MASB) endorses this definition as part of its ongoinCommon Language: Marketing Activities and Metrics Pr ...

Reliability Engineering
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time. The ''reliability function'' is theoretically defined as the probability of success. In practice, it is calculated using different techniques, and its value ranges between 0 and 1, where 0 indicates no probability of success while 1 indicates definite success. This probability is estimated from detailed (physics of failure) analysis, previous data sets, or through reliability testing and reliability modeling. Availability, testability, maintainability, and maintenance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Reliability
In the field of human factors and ergonomics, human reliability (also known as human performance or HU) is the probability that a human performs a task to a sufficient standard. Reliability of humans can be affected by many factors such as age, physical health, mental state, attitude, emotions, personal propensity for certain mistakes, and cognitive biases. Human reliability is important to the resilience of socio-technical systems, and has implications for fields like manufacturing, medicine and nuclear power. Attempts made to decrease human error and increase reliability in human interaction with technology include user-centered design and error-tolerant design. Factors Affecting Human Performance Human error, human performance, and human reliability are especially important to consider when work is performed in a complex and high-risk environment. Strategies for dealing with performance-shaping factors such as psychological stress, cognitive load, fatigue inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reliabilism
Reliabilism, a category of theories in the philosophical discipline of epistemology, has been advanced as a theory both of justification and of knowledge. Process reliabilism has been used as an argument against philosophical skepticism, such as the brain in a vat thought experiment. Process reliabilism is a form of epistemic externalism. Overview A broadly reliabilist theory of knowledge is roughly as follows: Given that ''p'' stands for any proposition (such as, ''the sky is blue''), then one knows that ''p'' if and only if ''p'' is true, one believes that ''p'' is true, and one has arrived at the belief that ''p'' is true through some ''reliable process.'' A broadly reliabilist theory of justified belief can be stated as follows: One has a justified belief that ''p'' if, and only if, the belief is the result of a reliable process. Moreover, a similar account can be given (and an elaborate version of this has been given by Alvin Plantinga) for such notions as 'warrante ...

Unreliable Narrator
In literature, film, and other such arts, an unreliable narrator is a narrator who cannot be trusted, one whose credibility is compromised. They can be found in a wide range from children to mature characters. While unreliable narrators are almost by definition first-person narrators, arguments have been made for the existence of unreliable second- and third-person narrators, especially within the context of film and television, but sometimes also in literature. The term “unreliable narrator” was coined by Wayne C. Booth in his 1961 book ''The Rhetoric of Fiction''. James Phelan expands on Booth’s concept by offering the term “bonding unreliability” to describe situations in which the unreliable narration ultimately serves to approach the narrator to the work’s envisioned audience, creating a bonding communication between the implied author and this “authorial audience.” Sometimes the narrator's unreliability is made immediately evident. For instance, a st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
