It seems like your question is incomplete. However, I can provide some common classifications of systems. Two types of systems often referenced in various fields include:

1. **Open Systems**: These systems exchange energy, matter, or information with their environment. Examples include ecosystems, organizations, and the human body.

2. **Closed Systems**: These systems do not exchange matter with their surroundings, although they may exchange energy. An example of a closed system is a sealed container of gas.

If you were referring to a different classification or specific context (like in technology, mathematics, etc.), please provide more details.
