master slave flipflop and edge triggered flip flop
There is a lot of confusion regarding the differences here.  A master-slave flip flop is edge triggered.  Please don't confuse latches with flip flops -- it will make everything seem very arbitrary.  A FF is just two back to back latches with opposite phase clocks -- the first is the master and the second is the slave.  The transparency windows are near-mutually exclusive so a lock and dam type flow is created. 

See my previous answers for more in depth information.  Also please know that both answers here already are wrong and will simply lead to confusion.
