CCITT (International Telegraph and Telephone Consultative Committee)
The CCITT (now part of the ITU-T) was an international organization responsible for developing standards for telecommunications, such as fax, telephony, and data transmission. It ensured different devices and networks worldwide could work together smoothly by setting technical guidelines. By creating these standards, CCITT helped improve the reliability, efficiency, and compatibility of global communication systems. It played a key role in coordinating progress as telecommunication technology evolved, making it easier for different countries and companies to connect through common technical rules.
