Basic Strategies
Explore basic free space management strategies used in virtualization to allocate memory efficiently. Understand how best fit, worst fit, first fit, and next fit algorithms work and learn their advantages and performance trade-offs. This lesson helps you grasp foundational allocation policies critical for optimizing memory usage in operating systems.
Now that we have some machinery under our belt, let’s go over some basic strategies for managing free space. These approaches are mostly based on pretty simple policies that you could think up yourself; try it before reading and see if you come up with all of the alternatives (or maybe some new ones!).
