How many pins does DDR RAM have?

  1. 168 pins

  2. 184 pins

  3. 240 pins

  4. 200 pins

The correct answer is: 184 pins

DDR RAM (Double Data Rate Random Access Memory) is a type of computer memory used for temporary storage of running programs and data. A common type of DDR RAM is DDR3, which has 184 pins. This is the type of DDR RAM used in most laptops and desktops. Option A, 168 pins, is the number of pins for older DDR RAM types such as DDR1 and DDR2, which are no longer widely used. Option C, 240 pins, is the number of pins for DDR4, which is the latest type of DDR RAM but is not as commonly used as DDR3. Option D, 200 pins, is the number of pins for DDR2 SO-DIMMs, which are used in some laptops but are not as common as DDR3. Therefore, the correct answer is B because it is the number of pins for the most commonly used type of DDR RAM.
