💡 Hint

Common Mistakes

Confusing internal fragmentation with external fragmentation.

Thinking fragmentation happens outside the allocated block.

Internal fragmentation happens when the memory allocated to a process is larger than what it actually needs, leaving unused space inside the allocated block.

2fill in blank

medium

Complete the sentence to define external fragmentation.

Operating Systems

External fragmentation happens when free memory is split into small [1] scattered around, making it hard to allocate large blocks.

💡 Hint

Common Mistakes

Mixing up blocks with processes or files.

Assuming external fragmentation is inside allocated blocks.

External fragmentation occurs when free memory is divided into small pieces scattered throughout, preventing allocation of large contiguous memory blocks.

Fix the error in the sentence describing internal fragmentation.

Operating Systems

Internal fragmentation wastes memory outside the allocated [1].

💡 Hint

Common Mistakes

Saying fragmentation happens outside the block.

Confusing internal with external fragmentation.

Internal fragmentation wastes memory inside the allocated memory block, not outside.

4fill in blank

hard

Fill both blanks to complete the sentence about fragmentation types.

Operating Systems

Internal fragmentation wastes space [1] the allocated block, while external fragmentation wastes space [2] allocated blocks.

💡 Hint

Common Mistakes

Mixing up inside and outside.

Using 'under' which is not correct in this context.

Internal fragmentation is unused space inside allocated blocks. External fragmentation is free space scattered between allocated blocks.

5fill in blank

hard

Fill all three blanks to complete the explanation of fragmentation effects.

Operating Systems

Internal fragmentation occurs due to [1] allocation sizes, causing wasted space [2] blocks. External fragmentation happens when free memory is [3] into small pieces.

💡 Hint

Common Mistakes

Confusing fixed and variable allocation sizes.

Mixing up inside and outside wasted space.

Not understanding how free memory is divided.

Internal fragmentation happens because of fixed allocation sizes, leaving wasted space inside blocks. External fragmentation occurs when free memory is split into small scattered pieces.
