If you want to know more about the difference between jail and prison and what a bail bondsman does, it would be a good idea for you to watch this video.
Most of the time, jails are much smaller than prisons. They are usually run by local governments.
Most of the time, jails are populated by people who have been arrested for minor offenses, such as misdemeanors. Most of the time, the sentences will be for less than a year. A lot of the time, they will hold individuals who are not able to post bail.
Prisons are very different, and there are no people who only have misdemeanors here. Generally, prisons are full of hardened criminals. They have been convicted of felonies, which are much more severe crimes. Prisons are generally run by state or even federal governments. Federal governments often hold people who have robbed banks and committed similar crimes, making state prisons more dangerous, as these tend to be home to more violent offenders. Both federal and state facilities can have minimum or maximum security, depending on the specific facility. Minimum security prisons often have more amenities and are said to be more like adult camps than prisons.
