Computer data is information processed or stored by a computer.

Data are units of information , often numeric, that are collected through observation. Although the terms "data" and "information" are often used interchangeably, these terms have distinct meanings.

There is a subtle difference between data and information. Data are the facts or details from which information is derived. Individual pieces of data are rarely useful alone. For data to become information, data needs to be put into context. Data are simply facts or figures — bits of information, but not information itself.

Data processing

A data processing system is a combination of machines , people, and processes that for a set of inputs produces a defined set of outputs. The inputs and outputs are interpreted as data , facts , information etc. A term commonly used synonymously with data or storage codes processing system is information system. The first machines used for data processing were punched card machines , now computers are used. Scientific data processing "usually involves a great deal of computation arithmetic and comparison operations upon a relatively small amount of input data, resulting in a small volume of output. Commercial data processing "involves a large volume of input data, relatively few computational operations, and a large volume of output. Information Systems IS is the field that studies such organizational computer systems.

Data procesing refers to the transformating raw data into meaningful output. Data Input - the collected data is converted into machine-readable form by an input device, and send into the machine. Processing is the transformation of the input data to a more meaningful form information in the CPU. Output is the production of the required information, which may be input in future. Data capture is the process of obtaining data in a computer-sensible form for at the point of origin the source document itself is prepared in a machine-sensible form for input.

Research process starts with the collection of data, which plays a significant role in the statistical analysis. However, in general, it indicates the facts or statistics gathered by the researcher for analysis in their original form. While data is an unsystematic fact or detail about something, information is a systematic and filtered form of data, which is useful. In this articl, you can find all the important differences between data and information. Basis for Comparison Data Information Meaning Data means raw facts gathered about someone or something, which is bare and random. Facts, concerning a particular event or subject, which are refined by processing is called information.

Data processing system

Data processing , Manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing. In the commercial world, data processing refers to the processing of data required to run organizations and businesses. Data processing Article Media Additional Info.

The words Data and Information may look similar and many people use these words very frequently, But both have lots of differences between them. It is not enough to have data such as statistics on the economy. Data themselves are fairly useless, but when these data are interpreted and processed to determine its true meaning, they becomes useful and can be named as Information. Information is data that has been processed in such a way as to be meaningful to the person who receives it. Data is the term, that may be new to beginners, but it is very interesting and simple to understand. It can be anything like name of a person or a place or a number etc. Data is the name given to basic facts and entities such as names and numbers.

Data vs. Information

Data is a raw and unorganized fact that required to be processed to make it meaningful. Data can be simple at the same time unorganized unless it is organized. Generally, data comprises facts, observations, perceptions numbers, characters, symbols, image, etc. Data is always interpreted, by a human or machine, to derive meaning. So, data is meaningless.

Data and information are similar concepts, but they are not the same thing. The main difference between data and information is that data are a part and information is the whole. Explore how data and information differ through definitions and examples. The word data can be used for a singular fact or a collection of facts.

 Н-ну, - заикаясь начал он, и голос его внезапно задрожал.

Difference between Information and Data

Он смотрел на нее с нескрываемым любопытством.  - Что ты сказала. Чем ты занята. - Я ничего не говорила, - ответила Сьюзан.

Члены группы будут уверены, что производят облаву на наркодельцов. Стратмор, несомненно, постарается проверить все лично и найти пароль из шестидесяти четырех знаков. Затем он его уничтожит, и Цифровая крепость навсегда исчезнет из Интернета. - Действуй своим маячком очень осторожно, - сказал Стратмор.  - Если Северная Дакота заподозрит, что мы его ищем, он начнет паниковать и исчезнет вместе с паролем, так что никакая штурмовая группа до него не доберется.

Difference Between Data and Information

Коммандер не спешил с ответом: - Автор алгоритма - частное лицо. - Как же так? - Сьюзан откинулась на спинку стула.  - У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста.

Сьюзан слушала его безучастно, от воя сирены у нее закладывало уши. Хейл же все время старался высвободиться и смотрел ей прямо в. - Как люди смогут защитить себя от произвола полицейского государства, когда некто, оказавшийся наверху, получит доступ ко всем линиям связи. Как они смогут ему противостоять.
