What do you mean by data information and processing in your computer?

Answer 1

Data analysis

Data Analysis is the domain from which the data are harvested is a science or an engineering field. Data processing and information systems are considered terms that are too broad and the more specialized term data analysis is typically used. This is a focus on the highly-specialized and highly-accurate algorithmic derivations and statistical calculations that are less often observed in the typical general business environment. In these contexts data analysis packages like DAP,gretl or PSPP are often used. This divergence of culture is exhibited in the typical numerical representations used in data processing versus numerical; data processing's measurements are typically represented byintegers or by fixed-point orbinary-coded decimal representations of numbers whereas the majority of data analysis's measurements are often represented by floating-point representation of rational numbers.

[edit]Processing

Basically, data are nothing but facts (organized or unorganized) which can be converted into other forms to make it useful, clear and practically used. This process of converting facts to information is Processing. Practically all naturally occurring processes can be viewed as examples of data processing systems where "observable" information in the form of pressure, light, etc. are converted by human observers intoelectrical signals in the nervous system as the senses we recognize as touch,sound, and vision. Even the interaction of non-living systems may be viewed in this way as rudimentaryinformation processing systems. Conventional usage of the terms data processing and information systems restricts their use to refer to the algorithmic derivations, logical deductions, and statistical calculations that recur perennially in general business environments, rather than in the more expansive sense of all conversions of real-world measurements into real-world information in, say, an organic biological system or even a scientific or engineering system.

Computer data processing is anyprocess that a computer program does to enter data and summarise, analyse or otherwiseconvert data into usable information. The process may be automated and run on a computer. It involves recording, analysing, sorting, summarising, calculating, disseminating and storing data. Because data are most useful when well-presented and actually informative, data-processing systems are often referred to as information systems. Nevertheless, the terms are roughly synonymous, performing similar conversions; data-processing systems typically manipulate raw data into information, and likewise information systems typically take raw data as input to produce information as output.

Data processing may or may not be distinguished fromdata conversion, when the process is merely to convert data to another format, and does not involve any data manipulation.
