Memory Management Basics Quiz

The memory manager's role is to efficiently manage memory by keeping track of which parts of memory are in use, allocating memory to processes when they need it, and deallocating it when they are done.

The memory hierarchy consists of cache (fast), main memory (medium), and disk (slow). It is important because it represents the different levels of memory with varying speeds and the operating system needs to abstract this hierarchy into a useful model and then manage the abstraction.

Having no memory abstraction means every program simply sees the physical memory. This limits the system to only have one program in memory at a time and does not allow for the possibility of having two running programs in memory simultaneously.

<p>In a system with no memory abstraction, if the first program writes a new value to a memory location, it would erase whatever value the second program was storing at that location, making it impossible to have multiple programs running in memory simultaneously.</p> Signup and view all the answers
