<title>Overview of instant messaging</title>
<p>
Instant messaging, sometimes abbreviated to IM, is a text-based means to
communicate instantly over the internet and the local network. While some
IM applications work with only one type of account, others, including
<link xref="introduction">Empathy</link>, provide IM facilities by using
<link xref="add-account">accounts</link> from different service providers.
Some of these even support audio and video calling.

Some instant messaging applications can be used to connect to chat rooms,
online places where like-minded people meet to talk. One popular means to
connect to several chat rooms is the Internet Relay Chat, also known as
<link xref="irc-manage">IRC</link>. IRC provides
<link xref="irc-join-room">public</link> chat rooms, which are open to
anyone who creates an account on the IRC Server, and private chat rooms,
which are <link xref="irc-join-pwd">password protected</link>
and open only to a select few.
