What is the difference between Busy and Offline statuses of an agent?

An agent at a chat window can display the following statuses:

• Online - Agents can accept chats and start the conversation with the client only if they are online.
• Busy - Agents cannot accept new chats but they can continue and finish existing chats.
• Offline - Agents cannot work on any chat when they are offline.
