A technician is given a failed memory module with 184 pins and is told to order a replacement. Which of the following modules will the technician order?

The correct answer is A. DDR. The pin count is the key identifier for DIMM generations: DDR (DDR1) uses 184 pins, DDR2 uses 240 pins, DDR3 also uses 240 pins (with a different key notch position), and DDR4 uses 288 pins. SODIMM is a form factor used in laptops and has different pin counts depending on the…

Explanation

The pin count is the key identifier for DIMM generations: DDR (DDR1) uses 184 pins, DDR2 uses 240 pins, DDR3 also uses 240 pins (with a different key notch position), and DDR4 uses 288 pins. SODIMM is a form factor used in laptops and has different pin counts depending on the generation. Since the failed module has exactly 184 pins, the replacement must be DDR (first-generation DDR SDRAM).
