understanding pc memory
Understanding Computer Memory. Understanding computer memory is very important because memory is what enables your PC to operate. Sure, your computer's CPU (central processing unit) is the computer's brain, but a brain is useless without memory.ew systems use a type of memory that can access data on the rising and falling edges of the system clock pulses. This means your computer can access the data in memory at twice the normal speed, hence the term Double-Data-Rate SDRAM (DDR-SDRAM). DDR-SDRAM is available in a 168-pin DIMM.
