What is the difference between stereo and mono?

There are different ways to extract sound. One method is mono, which is used for mainly talk shows or AM stations etc.. The mono extraction has one wave and sends sound through one channel. It can be identified by one black band on the tip of the silver or gold male end of the connections. Stereo runs through two channels and is mainly used in films and FM stations etc. Stereo has two waves usually labeled left to right. Stereo connections can be identified with two black bands on the tip of the silver or gold male end of the connection.
