IT or ICT?

Some people interchange IT (information technology) with ICT (information and communications technology), mainly because they do not know the real difference between the two terms.

IT, on the one hand, is the branch of engineering that deals with the use of computers and telecommunications to store, retrieve and transmit information. It spans a wide variety of areas that include computer software, information systems, computer hardware, and programming languages. (

ICT, on the other hand, is IT plus CT (communications technology). It is therefore IT with emphasis on telephony, broadcast media, and all types of audio and video processing and transmission. Moreover, ICT puts emphasis on society, on equal access to knowledge and technology vs. digital divide.

Introduction of the IT concept came way ahead, having been in mainly academic use in the 50s. While ICT was introduced in the 90s.

So which between the two must be used? Either of the two, but we like ICT more as it puts emphasis on human and social development.
