Information technology (IT) refers to anything related to computing technologies, such as hardware, software, networking, the internet, and the people who work with these technologies. IT is used for storing, protecting, processing, securing, transmitting, receiving, and retiring information. Advances in IT and the advent of personal computers in the 1980s moved the world into the information age and changed lifestyles. Networks connect computers globally, and cloud computing allows access to information from anywhere via the internet without needing large local storage. While IT provides benefits, it also presents risks like reduced employment and impacts on health from overuse. The future of IT remains uncertain but it is advancing rapidly.
