> Yes. A computer can be in an infinite loop, lose power, and then stop functioning.

Ok. Are these claims accurate?

1. All physical systems must eventually halt.

2. In many cases physical systems correspond to formal computational systems.

> Infinite Loop: A system is in an infinite loop when that system keeps returning to the same state making it unable to progress

A system is called deterministic if all future states can be calculated from complete knowledge of any particular state.

So then because the system is deterministic, we know that if it returns to a previous state it must keep returning to this state forever?

> Forever: A time period that ranges from t=now to t=infinity.

Right, it’s a period of time, but the word “infinity” is not clarifying for me. Maybe, a period of time with no end?
