First Fit vs Best Fit vs Worst Fit - Memory Allocation Methods in Operating Systems

Learn three fundamental memory allocation algorithms used in operating systems through a detailed comparison of First Fit, Best Fit, and Worst Fit methods. Explore how each algorithm approaches the problem of allocating memory blocks to processes, examining their respective advantages, disadvantages, and performance characteristics. Understand the trade-offs between allocation speed and memory utilization efficiency as you analyze how First Fit selects the first available block that fits, Best Fit chooses the smallest suitable block to minimize waste, and Worst Fit allocates the largest available block. Gain insights into when each method is most appropriate and how they impact system performance, fragmentation, and overall memory management in operating systems.
