🧩 Fragmentation Visualizer
▼Internal Fragmentation
Occurs in fixed-size partition schemes when a process is smaller than the partition it's allocated. The leftover space *inside* the partition is wasted.
External Fragmentation
Occurs in dynamic-size partition schemes. Free memory gets broken into small, non-contiguous blocks. Total free space may be enough, but it's not usable.
A new process might not fit, even if total free space is sufficient.
