COMPTIA A+ Practice Exam

How many pins does DDR SDRAM use?

1. 184 pins

2. 200 pins

3. 240 pins

4. 288 pins

The correct answer is: 184 pins

DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory) uses 184 pins. This type of memory is commonly used in computers and other electronic devices. Option B, 200 pins, is incorrect because it is not a common pin count for SDRAM. Option C, 240 pins, is incorrect because that is the pin count for DDR3 SDRAM, not DDR SDRAM. Option D, 288 pins, is incorrect because that is the pin count for DDR4 SDRAM, not DDR SDRAM. Hence, option A is the only correct answer.
