When a court suspends imposition of sentence and places a defendant on probation but later revokes probation, but later imposes sentence, what is the difference?

When a court initially suspends imposition of sentence and places a defendant on probation, but later revokes probation and imposes sentence, "two separate and distinct decisions are involved in its sentencing choice: (1) [t]o revoke probation; and (2) to sentence to state prison rather than place the defendant on probation on new or modified conditions." (People v. Cotton (1991) 230 Cal.App.3d 1072, 1080-1081.) "Once a probation violation occurs, the trial court has broad discretion in deciding whether to continue or revoke probation. [Citation.] However, due process principles require the trial court to articulate sufficient reasons supporting its revocation of probation." (People v. Jones (1990) 224 Cal.App.3d 1309, 1315.)
