Virtual memory management is a system that allows a computer to compensate for shortages of physical memory by temporarily transferring data from random access memory to disk storage. This process creates an illusion of a large contiguous memory space, enabling efficient multitasking and application execution beyond the physical memory limits.

Physical memory, often referred to as RAM, is the hardware component in a computer that stores data temporarily for quick access by the CPU, enabling efficient processing of tasks. It differs from storage memory in that it is volatile, meaning it loses its contents when the power is turned off, allowing for faster read and write speeds compared to non-volatile storage like hard drives or SSDs.

Random Access Memory (RAM) is a type of volatile memory used in computers to store data that is actively being used or processed by the operating system and applications. It allows for fast read and write operations, which significantly enhances the performance and speed of computing tasks by providing quick access to data compared to other storage types like hard drives or SSDs.

Application execution refers to the process by which a computer program is run by a computer's operating system, translating high-level code into machine-level instructions that the hardware can execute. It involves various stages such as loading the program into memory, managing resources, and executing instructions in a sequence determined by the program's logic and control flow structures.

Data transfer refers to the process of moving data from one location to another, which can occur within a single device or across networks. It is crucial for enabling communication between systems and ensuring the accessibility and integrity of data across different platforms.
