How is DDR2 RAM different from DDR RAM in terms of physical characteristics?

It has more pins
It operates at a higher voltage
It has fewer notches

The correct answer is: It has more pins

DDR2 RAM is different from DDR RAM in terms of physical characteristics because it has more pins. DDR2 RAM has 240 pins while DDR RAM has 184 pins. This is the main way to differentiate between the two types of RAM. Option B is incorrect because both DDR2 and DDR RAM operate at the same voltage of 1.8V. Option C is also incorrect because DDR2 RAM has the same number of notches as DDR RAM, which is one. Option D is incorrect because DDR2 RAM is actually smaller in size compared to DDR RAM.
