They're ALL protection orders. For some reason, the legislature felt the need to rename the order from "restraining order" to "protection order" a few years ago, without changing much of anything else about them.
The way they work in Colorado (and most if not all of the rest of the US):
You (the "petitioner") petition the county court to issue a PO.
The court issues a Temporary PO and sets a hearing date. The order is valid and in force, upon being served until the hearing date.
The hearing is for you and the restrained party (the "respondent") to go in front of the judge and argue about whether the order should be made permanent. If the judge says "yes," then it becomes permanent (but can be challenged by the respondent every few years). If the judge says "no," then the order expires and ceases to be valid.
The petitioner can ask for a variety of terms to be included: no contact at all, no weapons, no alcohol, must stay 100' away, whatever. But the terms you ask for need to have some reasonable relationship to whatever threat you perceived that made you petition for the order.
The best way to go forward would be to contact the court clerk for the county court where you live. They can't give legal advice but should have some self-help information that you can use.
