Though IT often refers to computer networks and computers, it refers to all layers of the comprehensive system of an organization. This includes operating systems, hardware, databases, servers, applications, storage, etc. The other aspects which are a part of IT infrastructure include; business phones, Internet phones, etc. IT is essentially the application of computers for the purposes of storing, retrieving, transmitting, and manipulating data, generally in the context of an enterprise. IT is regarded as a subcategory of Information and Communications Technology (abbreviated as ICT).
The term IT is usually used synonymously with the computer as well as computer networks, however, it also covers other various information distribution technologies, such as software, electronics, semiconductors, telecom, the internet, computer hardware, healthcare, engineering, e-commerce, computer services, and telecom equipment. IT is something that has been an inseparable part of human civilization. Humans have, for ages, stored, retrieved, manipulated, and communicated information since the time as far as that of Mesopotamia and Sumerians.
However, the term IT was first used in its modern context in a 1958 article written by Thomas L. Whisler and Harold L. Elavitt and published in the Harvard Business Review. Ever since then, the use of IT has become rampant. With the universal utility of IT, some ethical issues have been raised. Some of them include infringements of copyright by enabling download of files without due permission of such copyright holders; the rise of unsolicited emails; the presence of hackers; convenience in the access of personal data; the rise of websites that automatically install spyware or cookies for monitoring the online activities of a user, etc. These issues have attracted international attention and many international bodies and associations have laid down guidelines to prevent the unwarranted use of IT.
