What year did Imfomation communication technonlgy start in?

Information and communication technology (ICT) has roots that date back to the 19th century. The telegraph, invented in the early 1800s, allowed for the transmission of information over long distances. In the late 1800s, the invention of the telephone enabled instantaneous voice communication over wire. The development of radio technology in the early 20th century made it possible to transmit information without the use of wires. The first computers, developed in the mid-20th century, revolutionized the way information was processed and stored. The integration of these various technologies in the late 20th century led to the emergence of ICT, which has continued to evolve rapidly in the 21st century.
