The term sentence in law refers to punishment that was actually ordered or could be ordered by a trial court in a criminal procedure. A sentence forms the final explicit act of a judge-ruled process as well as the symbolic principal act connected to their function. The sentence can generally involve a decree of imprisonment, a fine, and/or punishments against a defendant convicted of a crime. Those imprisoned for multiple crimes usually serve a concurrent sentence in which the period of imprisonment equals the length of the longest sentence where the sentences are all served together at the same time, while others serve a consecutive sentence in which the period of imprisonment equals the sum of all the sentences served sequentially, or one after the other. Additional sentences include intermediate, which allows an inmate to be free for about 8 hours a day for work purposes; determinate, which is fixed on a number of days, months, or years; and indeterminate or bifurcated, which mandates the minimum period be served in an institutional setting such as a prison followed by street time period of parole, supervised release or probation until the total sentence is completed.
