Question from Operaring Systems 8th edition Chapter 8, 15, a. Can't understand delta 5 and 6 table. My solution is this; for example, delta 4 have four page frames. In line 9, 3rd frame that contains 3 is deleted because of 4th frame that contains 3. Other frames is not deleted now, but disappear every next line is coming. For that reason, line 10 don't have page number 2, and line 11 don't have page number 1. But this solution can't explain delta 5 and 6. So please can you give me the right solutions? Thanks :D
