Kids Encyclopedia Facts

Welcome to the world of IRC clients! Imagine you want to chat with friends or join online communities, but not through typical social media apps. That's where IRC comes in!

Internet Relay Chat (IRC) is a way to chat online using text. It's like a big chat room system where people connect to different servers and channels (which are like specific chat rooms). To join these chats, you need a special program called an IRC client.

This article helps you compare different IRC clients. Think of them as different apps you can use to connect to IRC. Some are simple, some have lots of features, and some work on different types of computers. Let's explore some of the most popular ones!

What are IRC Clients?

IRC clients are software programs that let you connect to IRC networks. Once connected, you can chat with other people in real-time. You can join public channels to talk about specific topics or send private messages to friends.

  • IPv6: A newer way for computers to connect on the internet.
  • SSL and TLS: These are like secret codes that keep your messages private and safe when you send them over the internet.
  • SASL: Helps you log in securely to an IRC server.
  • OTR: Adds an extra layer of privacy to your direct chats.
