Which of the following is a disadvantage of the Buddy System? A) Reduces fragmentation B) Requires all allocation units to be powers of two C) Fast allocation D) Efficient merging

B) Requires all allocation units to be powers of two

Fill in the blank: The ______ eliminates fragmentation caused by allocations and deallocations by retaining allocated memory for reuse.

Slab Allocation

True or False: Internal fragmentation occurs when a process is allocated a memory block larger than the amount requested.

True

Riddle: I split memory into fixed-size blocks of powers of two, allocating to processes as requested. What am I?

Buddy System

What is the primary advantage of using slab allocation in memory management?

No memory is wasted due to fragmentation because each unique kernel data structure has an associated cache.

Fill in the blank: The process of mapping from one address space to another address space is called ______.

Address binding

Which of the following methods is NOT a common partition allocation method? A) First Fit B) Best Fit C) Random Fit D) Worst Fit

C) Random Fit

True or False: The Slab Allocation technique immediately frees up memory space after an object is no longer needed.

False. The Slab Allocation technique retains allocated memory for reuse upon subsequent allocations.

What is coalescing in the context of memory management?

Coalescing is the process of merging adjacent free memory blocks to form larger segments.

Fill in the blank: The ______ is a hardware device that performs address translation from logical to physical addresses.

Memory Management Unit (MMU)
