Operating Systems

THE FOLLDWING TABLES IN MEMORY ARE CURRENTLY BEING USED BY PROCESS 'A'. ANSWER THE FOLLOWING OUESTIONS USING THE INFORMATIO GIVEN.

      A) V=(6,00,0F0)        R=

      B) V=(3,00,ABC)        R=

      C) V=(2,03,00F)        R=

      D) V=(1,01,123)        R=

      E) V=(7,01,456)        R=

EXAMPE:
     V=(3,01,D5F) Translates to R=(015D5F)
