IRC stands for which term?

• A. Internet Relay Chat
• B. Internet Remote Chat
• C. Internet Relay Code
• D. Interface Relay Chat

Answer: (A)

Understanding what each word in an acronym describes helps you decode these terms in networking. For IRC, the words are Internet, Relay, and Chat. Internet points to the global network it runs on, Relay indicates how messages are passed through servers to reach participants, and Chat tells you the service is for real-time text conversations. That makes Internet Relay Chat the correct expansion.

The other options don’t fit because they replace a key word with one that changes the meaning: Remote suggests distance rather than the relay of messages, Code isn’t used in this context at all, and Interface would imply something related to user interfaces rather than the messaging protocol.
