Windows 98 utilizes a memory management system based on the 32-bit Windows architecture, which allows for better multitasking and memory allocation than its predecessor, MS-DOS. It employs a virtual memory system that uses both RAM and disk space to extend the apparent amount of memory available to applications. The operating system can manage up to 2 GB of memory per process and supports a total system memory of up to 4 GB, although practical limits are lower due to hardware and software constraints. Additionally, Windows 98 incorporates features like memory protection and improved handling of multimedia applications, enhancing overall system stability and performance.
Unlike Windows 98, which ran on top of MS-DOS and had an external memory manager, Windows XP's memory manager is built into the kernel.
