Which file allocation method stores blocks of a file in an ordered sequence linked together via pointers, eliminating external fragmentation but making random access slow?
Explanation:
Linked allocation chains blocks together using pointers, allowing dynamic size expansions but requiring linear scanning to read a specific internal offset.
What mechanism does an operating system use to simulate an environment where multiple processes run concurrently on a single CPU core by switching between them rapidly?
Explanation:
Time-slicing leverages rapid, scheduled context switching to give users the illusion of smooth, concurrent application execution on a single core.
