Introduction Computer skills are a special technology and therefore raise issues and specific ethical and legal considerations. It is therefore appropriate to characterize the ethics of Informatics and show why this field within professional ethics is an emerging subfield of particular importance to engineers (Brenner, 2007). Although in this topic include concepts of ethics and law is not to be confused terms. Professional ethics in principle a philosophical discipline, deals with the obligations and standards of man, not necessarily coded, which define the proper practice of the profession within the human values of higher order. To avoid confusion, try to distinguish moral ethics that has to do with religious values, while the concept of professional ethics that is what interests us is synonymous with the ethical rules (deontology is that part of philosophy that deals with the origin the nature and purpose of the duty, as opposed to ontology, which deals with the origin, nature and purpose of being) (Brenner, 2007). While the right has to do with the written laws governing human behavior to others, in a given society, applied ethics is manifested in the daily lives of people and their individual and social responsibilities from all dimensions social life. The balance can be achieved between moral rules (if you're religious) ethical and legal is the best guarantee for the effective control of a profession and as a whole to a coherent living within a society (Brenner, 2007). If all the rules were ethical, the person generally classify as unethical or immoral, would not feel affected by them and act with impunity and without any brakes. On the contrary, if everything is reduced to legal rules, we know from experience that you can get fatally to its breach, and that the sanction cannot be performed as often as needed apparently (Brenner, 2007). Therefore they must live together the legal system, which provides for the punishment of the worst situations, rules relating to the internal jurisdiction of the people, that is, there must be ethical standards. In our case we can say that there is no ethics of computing rather than to the extent that the technologies are perceived as constituting personal and social life, and when confronted with the values that guide social development. In terms of legislation, the computer world is essentially controlled by two types of rules: the law protecting individual freedoms (the new Penal Code and LORTAD, Spain), Intellectual Property law and the law of freedom of communications (provided the European and global release for 1997 and 1998). In the professions, ethics is in this intermediate zone where not all are absolute standards of right and exclusive ethical, not all are legal norms. A reflection on ethics and codes of conduct does not escape the perspective of the respective roles of ethics, law and codes themselves, and must wonder also about the sense of renewal of ethics in the domain of technology ...
