Copying is the duplication of information or an artifact based only on an instance of that information or artifact, and not using the process that originally generated it. With analog forms of information, copying is only possible to a limited degree of accuracy, which depends on the quality of the equipment used and the skill of the operator. With digital forms of information, perfect copying is not only possible, but is, almost by definition, the norm. Copy and paste is frequently used for information a computer user selects and copies to an area he or she wishes.

Most high-accuracy copying techniques use the principle that there will be only one type of possible interpretation for each reading of data, and only one possible way to write an interpretation of data.

manuscript culture

Prior to the invention of the printing press, the only way to obtain a copy of a book was to copy it out by hand. Throughout the Middle Ages, scribes copied entire texts as a way of disseminating and preserving religious texts.

In art

In visual art, copying the works of the masters is a standard way that students learn to paint.

Biological copying

Organically, copying of genetic information can take place using DNA replication, which is able to copy and replicate the data with a high degree of accuracy, but mistakes are common, and occur in the form of mutations. However, in the process of DNA repair, many of the mistakes are resolved by checking the copied data against the original data.

Digital copying

This principle is applied digitally, such as in hard disks, but in a different form. The magnetised data on the disk consists of 1's and 0's. Unlike DNA, it only has two types of information, rather than four types, however, it still has a polar concept of transfer. In this case, the read-write head acts as an intermediary. A data section reading "1", can only trigger one type of response, and "0" for the other. These responses from reading are converted into an electrical form that gets carried through the circuits. Although this can be later converted and processed for other ways of using the data, which can be modified, if a file were being copied from one hard disk to another, the principle ensures that the data is transferred with high fidelity, because only each type of signal can only trigger one type of data write, in this case a 1 or a 0. This excludes exceptions where the data was written incorrectly or the existing data has been corrupted while on the disk such that no distinction can be made, but usually the hard disk returns the area as unreadable. The other concept that using digital copying is website copy[1], digital copying has more interpretation than just the basic concept of disk read and write itself. Digital Copy is a sample of interpretation of digital copying.

Copying rights

The concept of copying has a particular significance in certain areas of law. In each of the primary areas of intellectual property law, a number of cases have refined the question of what exactly constitutes the kind of copying prohibited by law, especially in areas such as copyright law.

A related concept is plagiarism, copying others' work and passing it off as one's own.
