Jargon and Argot

What is the difference between this two words? The first one can be defined as "the vocabulary peculiar to a particular profession or group". In the other hand, argor means "specialized vocabulary to a class or group, especially one devised for private communication". Some examples of argot may be:

• Sport language: any sports specifical vocabulary. For example, in golf the words "par", "bogey" or "birdie" can be considered sports argot, as its definition isn't known by everyone.
• Legal language: all the vocabulary used by lawyers and judges, specially the one used it trials.
• Scientific language: the words scientists use, technical words. For example, doctors; when they talk about some deseases or about particular instruments. Common people doesn't understand anything of this.
