Which of the following memory modules uses a 240-pin connector?

The correct answer is C. DDR2. DDR2 SDRAM uses a 240-pin DIMM connector. This is a key distinguishing characteristic: DDR (A) uses 184 pins, SIMM (B) modules use either 30 or 72 pins, and RAMBUS (D) RIMM modules use 184 pins. DDR3 also uses 240 pins but has a different notch position, making it physically…

Explanation

DDR2 SDRAM uses a 240-pin DIMM connector. This is a key distinguishing characteristic: DDR (A) uses 184 pins, SIMM (B) modules use either 30 or 72 pins, and RAMBUS (D) RIMM modules use 184 pins. DDR3 also uses 240 pins but has a different notch position, making it physically incompatible with DDR2 slots despite the same pin count. Memorizing pin counts per memory generation is a common A+ exam objective.
