• Internal Fragmentation
• With each block of equal size.
• A process, no matter how small, will get allocated an entire
block.
• There are often spaces left in the block.
• Sum of all unused space may equal one or more unused
blocks.
• These unused space are wasted and cannot be used by other
process since the entire block is reserved for the process
owner already.
• Solution — Unequal-size (reduce) or Dynamic Partitioning (fix)
