Memory management
Operating system function allocating and deallocating memory to processes. Efficient memory management is critical for system performance. Techniques: paging, segmentation, virtual memory.
Real World
When you open Chrome with dozens of tabs, Windows allocates separate memory regions for each tab process — if one tab crashes, the others survive because the OS kept their memory isolated.
Exam Focus
Compare paging and segmentation by stating fixed vs variable sizes, then link each to its fragmentation type.
