Information and Communication Technology (ICT) is a broader term covering information processing and communication technologies. It includes hardware, software, telecommunications, and internet services. ICT professionals integrate these technologies for effective communication within organizations and between individuals.

While IT and ICT are closely related, IT focuses on managing information through technology, while ICT extends to technologies enabling communication and collaboration.
