정보통신용어사전 (ICT Terminology Dictionary) is an educational and reference program developed by TTA. It aims to standardize and provide explanations for terms related to communication, broadcasting, computers, the internet, and information security.

The program offers a wide range of ICT terms along with detailed explanations to help users understand their meanings. It also allows users to propose new terms that are not yet included in the dictionary. These proposed terms are reviewed and, if approved, added to the dictionary.

정보통신용어사전 is supported by the Ministry of Science and ICT and developed by the Korea Information and Communication Technology Association (KICTA) with funding from the Korea Information and Communication Technology Promotion Agency (NIPA).
