The dictionary of the Turkish Language Institution defines informatics as "the science of processing of information used by humankind in communication in technical, economic and social fields, especially through electronic machines, in a regular and rational way and which is the basis of science, informatics" or "the science of processing of information used by humankind in communication in technical, economic and social fields, especially through electronic machines, in a regular and rational way and which is the basis of science." Applied science that examines the phenomenon of information, information retention, access systems, processing, transmission and use of information with the benefit of society and humanity in mind. IT, which is an interdisciplinary teaching and service sector, includes the design, development and production of various tools used in informatics and information access systems, including computers. Furthermore, many topics within the field of automatism, which include techniques for the automatic regulation of all kinds of industrial production, are broadly within the scope of informatics.
Although there is no common definition of cybercrime, the most widely accepted definition is the one made at the Paris Meeting of the Commission of Experts in the European Economic Community in May 1983: “ Any kind of behavior performed illegally, unethically or unauthorized in a system that automatically processes information or transmits data.”
Difficulty in obtaining complete and accurate statistics of crimes committed in the field of informatics and the failure to calculate the real damage caused by them, and the developments and expansions in this field that cannot be followed prevent from defining cybercrimes sufficiently. Since it is not possible to draw a framework on cybercrimes, these crimes are called "unlined frame crimes.” According to Karagülmez, a cybercrime is defined as the crime aimed at information systems or committed using the information system.
Cybercrimes are classified in various ways by various sources according to criteria such as whether the computer was a purpose or a means in crime, violation of property rights, connection with information systems, use of computers, and perpetrator of the crime.
