DDR PC3200 memory is a type of double data rate synchronous dynamic random access memory (DDR SDRAM) that is commonly used in personal computers. It has a high transferring rate of 3200 megabytes per second, represented by the "3200" in its name. DDR PC3200 RAM can store, process, and retrieve data for the central processing unit at a fast speed of 400MHz, but requires more power than slower memory types. It is considered volatile storage that is vulnerable to viruses and other threats.
