Slide 3 Text vs Binary Files (review) 8/25/2013 1:19 PM

Slide 4 Binary Files – A Brief Introduction Reading and writing to and from binary files is more efficient than processing text files since no conversion (from internal machine level representation to characters) is necessary The fields you write are written directly, in sequence, one at a time, without conversion 8/25/2013 1:19 PM
