What is the difference between a denomination and a movement?

I grew up raised in an Apostolic(Oneness-)Pentecostal church that affirmed O.S.A.S., I was always told our denomination was Pentecostal, but I see some refer to Pentecost as a movement, and U.P.C. as a denomination. What is the difference? Is one an umbrella term for all who affirm a particular title in the name of their doctrinal beliefs group? e.g. Would a Southern Baptist Church and a Calvary Baptist both be called: baptist in movement, but Southern Baptist for the denomination and Calvary Baptist for the denomination?
