FIX is an open protocol that is used for the networking of financial transactions and information - in English that means that orders and quotes can be sent between computers without the computers having to be running the same software or operated by the same company.
FIX is only directly relevant if you are a developer wanting to write a program that uses FIX to send/receive orders. If you are not into writing lots of software yourself, it still may become useful through a 3rd-party app that allows you to enter your trading system and have it executed. This would be similar to how Omega will be tying in their TradeStation Pro to a broker to allow a trading system to actually execute orders (although I doubt their software uses FIX).
