It is very common for a layman to confuse between the words IT and ICT. IT stands for Information Technology and ICT stands for Information and Communication Technology. It is of no shock that colloquial use of the word IT and with the same full form, ICT is also assumed to be the same as IT. But, here lies the catch, they are not the same.
Information Technology pertains to the hardware, software, and user skills associated with a stand-alone computer or laptop, while Information Communications Technology relates to networked equipment (LAN/WAN) that allows for intra-network and inter-network communication via email and the Internet. In short, IT refers to an entire industry that uses computers, networking, software and other equipment to manage information. ICT is an integration of information technology with communication technology.
Any process involving information exchange over the internet uses ICT. For example voice calls, e-mails, video conferencing, processing business data via applications, etc. Recently there has been a drastic change in the ways data is gathered, archived, and used in the businesses and government institutions. Gone are the days when the workplace was filled with papers and files. Gone are the days when one had to spend hours evaluating sheets of business data manually and was too prone to errors. That also meant error in one page could create in the succeeding pages too.
