External Fragmentation

How much external fragmentation $($in bytes$)$ does this current state of the heap have? Don't include units.

Incorrect

Question $3$

SUBMITTED

Internal Fragmentation

How much internal fragmentation $($in bytes$)$ does this current state of the heap have? Don't include units.

Correct

Explanation

Non$-$payload portions of the allocated blocks count as internal fragmentation, so it's the sum of $($total size $-$ payload size$)$ of blocks $1,3,$ and $5.$

Question $4$

SAVED

First Fit

Assume that block $5$ is the most recently allocated block. If we use a first fit policy, which block will be used for malloc$(1)?$

Tip: Enter just the block's number in the list, e$.$g$.,3.$

Question $5$

Next Fit

Assume that block $5$ is the most recently allocated block. If we use a next fit policy, which block will be used for malloc$(1)?$

Tip: Enter just the block's number in the list, e$.$g$.,3.$

Question $6$

Best Fit

Assume that block $5$ is the most recently allocated block. If we use a best fit policy, which block will be used for malloc$(1)?$

Tip: Enter just the block's number in the list, e$.$g$.,3.$
