Which DDR type is PC2-5300?

  1. DDR

  2. DDR2

  3. DDR3

  4. DDR4

The correct answer is: DDR2

PC2-5300 refers to DDR2 memory. The designation "PC2" indicates that it is a version of Double Data Rate 2 (DDR2) memory, as opposed to other generations like DDR, DDR3, or DDR4. The number "5300" signifies the peak bandwidth of the memory, which corresponds to a data rate of 533 MHz. DDR2 memory was introduced as a successor to DDR and features improvements in speed, power efficiency, and performance, making it a distinct type compared to earlier and later DDR generations. Each DDR type has unique characteristics and specifications, so knowing the appropriate designation helps in identifying the correct memory type for compatibility with a motherboard or system.
