Explanation & Hint:
DDR SDRAM (Double Data Rate Synchronous Dynamic RAM) typically refers to the original DDR memory, which has been superseded by newer generations. It generally has a 184-pin connector for DIMMs and operates at 2.5 volts.
DDR2 SDRAM improves upon the original DDR by using less power and providing higher speeds. It typically comes with a 240-pin connector and operates at 1.8 volts.
DDR3 SDRAM further improves upon DDR2 with even higher speed and lower power consumption. It also has a 240-pin connector but operates at 1.5 volts.
GDDR SDRAM (Graphics Double Data Rate SDRAM) is often used in graphics cards. It is optimized for high bandwidth and is not typically used for general-purpose computing in PCs.
DDR4 SDRAM is the most recent generation of DDR memory. It has a 288-pin connector and includes features like improved data rates, increased transfer rates, and more efficient power consumption compared to DDR3. It operates at a lower voltage of 1.2 volts but can also be found in variants that use 1.35 volts for low-power operations.
