How is memory management done using bit maps?

A bit map is here in this we signify the bit value as 0 or 1.

1-hole

0-process

In this we are able to represent the process and hole separately. In one line of this bit map will have eight spaces

!!!

!!!!

!!!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

Here the red colored shows free holes in he bit map we are able to represent this as follows

1	1	1	1	1	0	0	0
1	1	1	0	0	0	1	1
1

1-represents a process

0-repressents a hole
