What is the difference between a misdemeanor and a felony?

A:
These words take on diffferent meaning in various states and the federal system.  In Virginia, Misdemeanors are generally defined as criminal charges that may carry no more than 12 months in jail for each count.  Felonies are all criminal charges that might carry more than 12 months in jail or prison, although many felonies will result in probation and no actual prison time if the client is successful on probation.
