Question

Which characteristic describes DDR3 SDRAM?

A) Higher data transfer rates than DDR2
B) Lower power consumption than DDR4
C) Greater capacity than DDR
D) Reduced latency compared to DDR4

Answer 1

DDR3 SDRAM is known for its higher data transfer rates compared to DDR2 and improved power efficiency due to its lower operating voltage. It does not, however, have lower power consumption or reduced latency when compared to DDR4, nor does it inherently offer greater capacity over original DDR RAM.

Step-by-step explanation:

DDR3 SDRAM is a type of RAM (Random Access Memory) that stands for Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory. Compared to its predecessor DDR2, DDR3 SDRAM offers various enhancements. One of the key characteristics of DDR3 is its higher data transfer rates compared to DDR2, allowing more bandwidth and better performance for memory-intensive applications. Moreover, it operates at a lower voltage (1.5 volts) than DDR2, which typically requires 1.8 volts, leading to improved power efficiency.

However, DDR3 doesn't necessarily have a lower power consumption than DDR4, the subsequent generation of RAM. Furthermore, DDR3 typically does not offer greater capacity over the original DDR, but it does support larger capacities than its predecessors within its generation. Lastly, it also doesn't have reduced latency compared to DDR4; instead, DDR4 often has improvements in this area over DDR3.
