Which statement is true regarding single and double sided memory?

1. Single sided memory has a higher capacity.

2. Double sided memory uses more power.

3. Single sided memory uses half the number of memory modules as double sided memory of the same capacity.

4. Double sided memory is faster than single sided memory.

The correct answer is: Single sided memory uses half the number of memory modules as double sided memory of the same capacity.

The statement that single sided memory uses half the number of memory modules as double sided memory of the same capacity is accurate because of the way memory modules are designed. Single sided memory modules have memory chips on only one side, while double sided memory modules have chips on both sides. When two memory modules have the same total capacity, the double sided module typically can hold the same amount of memory in fewer physical modules compared to using single sided modules. For example, if you had a total of 8GB of memory, you could achieve this with a single double sided module or use two single sided modules, effectively illustrating that in this context, single sided memory modules would require twice as many to match the same total capacity as a single double sided module. This design aspect translates into practical considerations, such as fewer slots used on the motherboard and potentially better compatibility in some scenarios where space is a concern. Furthermore, using fewer memory modules can simplify installation and increase the number of available slots for future upgrades. Other statements either make generalizations about power consumption or performance that do not universally apply, making the chosen answer the most accurate in describing the relationship between single and double sided memory capacities.
