ⓘ Data ..



Data are characteristics or information, usually numerical, that are collected through observation. In a more technical sense, data is a set of values of qualitative or quantitative variables about one or more persons or objects, while a datum is a single value of a single variable. Although the terms "data" and "information" are often used interchangeably, these terms have distinct meanings. In popular publications, data is sometimes said to be transformed into information when it is viewed in context or in post-analysis. In academic treatments of the subject, however, data are simply uni ...


Big data ethics

Big data ethics also known as simply data ethics refers to systemizing, defending, and recommending concepts of right and wrong conduct in relation to data, in particular personal data. Since the dawn of the Internet the sheer quantity and quality of data has dramatically increased and is continuing to do so exponentially. Big data describes this large amount of data that is so voluminous and complex that traditional data processing application software is inadequate to deal with them. Recent innovations in medical research and healthcare, such as high-throughput genome sequencing, high-re ...


Data acquisition

Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the initialisms DAS or DAQ, typically convert analog waveforms into digital values for processing. The components of data acquisition systems include: Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values. Analog-to-digital converters, to convert conditioned sensor signals to digital values. Sensors ...


Data politics

Data politics encompasses the political aspects of data including topics ranging from data activism, open data and open government. The ways in which data is collected, accessed, and what we do with that data has changed in contemporary society due to a number of factors surrounding issues of politics. An issue that arises from political data is often how disconnected people are from their own data, rarely gaining access to the data they produce. Large platforms like Google have a "better to ask forgiveness than permission" stance on data collection to which the greater population is large ...


Data redundancy

In computer main memory, auxiliary storage and computer buses, data redundancy is the existence of data that is additional to the actual data and permits correction of errors in stored or transmitted data. The additional data can simply be a complete copy of the actual data, or only select pieces of data that allow detection of errors and reconstruction of lost or damaged data up to a certain level. For example, by including additional data checksums, ECC memory is capable of detecting and correcting single-bit errors within each memory word, while RAID 1 combines two hard disk drives HDDs ...


Definitive diagnostic data

Definitive diagnostic data are a specific type of data used in the investigation and diagnosis of IT system problems; transaction performance, fault/error or incorrect output.
