Today i'm going to discuss about internet relay chat(irc). Most of us are familiar with instant messaging. The main difference between IM and IRC is that in irc users on channels normally see everything other users talk i.e. it is real-time nd public conversation area.(although most IM also supports irc style group chat as well). IRC is actually a network of servers that are connected to each other, creating an interconnected network between these servers.
So what is the significance of irc in hacking? Well it is place where most of the hackers meet. There will be group discussions on hacking and many other things you need to learn. Just join a group and learn through the group discussions. It also supports file transfers between connected users, using a method called DCC to transfer data. So you can share resources also in irc.
You can do internet relay chatting by downloading an irc client. There are different irc clients for different operation systems. For windows its mirc, ircll for linux, snak for mac etc. Download one of the clients and start chatting with hacker.
