RAM (Random Access Memory) is a computer component for storing data sent from the computer, waiting to be processed by it.
There are several types of random access memories, here are the main types :
- SDRAM (Synchronous Dynamic RAM) 168-pin strips.
- DDR SDRAM (Double Data Rate Synchronous Dynamic RAM) 184-pin strips.
- DDR2 SDRAM (Double Data Rate Two SDRAM) 240-pin strips.
- DDR3 SDRAM (Double Data Rate SDRAM Three) 240-pin strips.
The most common memory is undoubtedly the DDR/DDR2/DDR3, the SDRAM is doomed to disappear in favor of faster memory.
The DDR is used on machines from generation Pentium III, 4 and AMD Athlon.
DDR2, when she was found on newer PC as the latest Pentium 4, the first generation of Core2Duo, Core2Quad, Phenom, Athlon.
DDR3, when her memory is faster than ever and is on the latest generation of machine based Core2Duo, Core2Quad, and the latest i3, i5, i7, Phenom II, Athlon II.
