Imagine you're in a big room with your friends, and you all want to talk to each other. But instead of using your voices, you type what you want to say on a computer. That's what IRC is. It's a big virtual room where people can talk to each other by typing.
Now, let's say you have a robot friend who can join you in this virtual room. This robot friend is called an IRC Bot. It can do things like help people find information or play games with them.
For example, if someone wanted to know what the weather is like outside, the IRC Bot could look up the current weather for them and tell them in the chat. Or, if someone wanted to play a game of trivia, the IRC Bot could host the game and keep track of the scores.
IRC Bots are really useful because they can do tasks that humans might not have the time or ability to do. Plus, they can work 24/7 without getting tired or needing a break.
Overall, an IRC Bot is like a helpful robot friend that can join you in a virtual room and do things for you.
