Virtual memory in OS
Virtual memory is a cornerstone of modern operating systems, enabling efficient use of physical memory while allowing processes to execute as if they have access to unlimited memory. It bridges the gap between a system’s limited RAM and the application’s memory demands by using secondary storage. This article explores the fundamentals of virtual memory, its…

Memory Hierarchy: Cache, Main Memory, and Secondary Storage
Memory hierarchy is a structured arrangement of storage systems in a computer, designed to bridge the gap between the CPU’s high processing speed and the slower memory units. This hierarchy ensures efficient data access by prioritizing faster, smaller, and costlier memory closer to the CPU, while larger, slower, and more economical memory resides farther away.…
