Both. You could, for example, take away a teenagers cell-phone (no!) or enforce a curfew.
introducing something unpleasant

consequence.
Punishment involves adding an undesirable consequence to decrease the likelihood of a behavior occurring again, whereas negative reinforcement involves removing an aversive stimulus to increase the likelihood of a behavior being repeated. Punishment aims to decrease behavior, while negative reinforcement aims to increase behavior. Negative reinforcement strengthens a behavior by removing something unpleasant, while punishment weakens a behavior by adding something unpleasant.
A consequence is something that results from an action.An action results in a consequence.
When you enjoy doing something or something is pleasurable to you. such as "I like to dance" or if you want to do something such as "I would like to eat" :)
Addiction is when a person becomes so accustomed to the pleasurable sensation of doing something that he or she continues to do it over and over, even after it has ceased to be pleasurable.
Punishment is any event that decreases the likelihood of something to occur while reinforcement is any event that increases this likelihood. Now negative reinforcement is going to increase the likelihood of something occurring by taking away an aversive stimuli. For example, if you do your homework now, you won't have to take out the trash later.Exploring Psychology by David Myer
It depends on the context but it's typically not something that you announce when introducing yourself.
Punishment is a moral concept; someone has done something wrong and therefore deserves to suffer a punishment. Negative reinforcement is not a moral concept but a pragmatic concept; we do not want someone to do something, therefore we give them a reason not to do it, in the form of some undesired consequence. Of course, the actual process of either punishment or negative reinforcement could turn out to be exactly the same. Only the motive is different.
It can minimize the seriousness of something
It's not about you admitting, or feeling regret, about what you've done. It's about preventing you from doing it a second time. In my eyes, if one were to admit to something, and expect to be let-off without punishment, it shows that they really have no regret to their action.
