EDO RAM, or Extended Data-Out Random Access Memory, is a type of computer memory commonly used in personal computers during the 1990s. It is an improvement over conventional DRAM, allowing faster data access by overlapping memory read cycles, which increases overall system performance.
For photographers and digital artists working on older PCs, EDO RAM provided better performance when handling large image files, running photo-editing software, or multitasking between applications. Although largely obsolete today, understanding EDO RAM is useful for historical context and for working with legacy computer systems.
