relationship between computer data and information

A lot of people believe that there is no difference between data and information in computer terms. Data can be a string of characters, numbers. Data processing is, generally, "the collection and manipulation of items of data to produce meaningful information." In this sense it can be considered a subset of information processing, "the The Census Bureau first made limited use of electronic computers for the United States Census, using a External links[ edit]. Key difference: Data and information are interrelated. Data usually refers to get information. In computing, it can be said that data is the computer's language.

Data is in an unorganized form, i. On the other hand, when the data is organised, it becomes information, which presents data in a better way and gives meaning to it. Data is based on observations and records, which are stored in computers or simply remembered by a person.

As against this, information is considered more reliable than data, as a proper analysis is conducted to convert data into information by the researcher or investigator. The data collected by the researcher, may or may not be useful to him, as when the data is gathered, it is not known what they are about or what they represent?

Conversely, information is valuable and useful to the researcher because it is presented in the given context and so readily available to the researcher for use. If you go to any tax collection department or municipal office you will find a high amount of files stacked here and there.

Modem rules, regulation and law requires every transaction to happen in a written form, may be an agreement, application, voucher, bill, letter, memo, order etc. Paper files require a high amount of storage space and paper storage creates several other problems like fire risk, spoilage and deterioration by way of aging microorganism and humidity etc. In modem days information is needed to run man's own livelihood to run a system or process or to command a business.

The amount of information is growing very rapidly. The current age of information demands computer literacy to be accompanied by information literacy as employers' dependence is. The impact of information revolution has been extended to each individual in the society and it is much faster than industrial revolution. The migration from industrial age to an information age has ended the repetitive effort of workers by replacing them with computer software, robots with artificial intelligence have replaced the humans, and multiprocessing computers have replaced office workers with typewriters.

Computer Data and information

The knowledge is derived from the information contained in fundamental science derived from experiments, rules, regulations commonly agreed by experts. A program is a set of step-by-step instructions which tells the computer exactly what to do with input in order to produce the required output.

Processing The instructions about what to do with the input are contained in a program. During the processing stage the computer follows these instructions using the data which has just been input. What the computer produces at the end of this stage is called output. Output This stage of computing is concerned with producing the processed data as information in a form that is useful to the user. Output devices are used to do this.
